Wayne, thank you so much for the MCOR-4 part #. Love your videos. First time golf cart owner with a 2002 club car DS. Your videos are by far the most helpful for a 61 year old cancer survivor with what my wife calls kemo brain, I call CRS (can’t remember shit) Keep the videos coming. Hope your well.
Hello! What does jumping the 2 wire connector on MCOR do? I have a 2017 club car precedent with intermittent moving issues. It’ll work fine then stop working and work again. Saw other videos of bypassing the MCOR. Wondering if i can do that for a cheap fix.. just fixed a rattling loose brake pedal and a shorted horn. Thanks for the video and help !!!!!
I have used both, and I will only use the OEM mcor for a customer. Although it costs alot more, it is worth it. I tried using the Chinese mcors for awhile, and they would fail in less than a year. Then I had customers that thought I was using "used" parts since they did not last And it was a hassle having ho back and replace them with the good ones ( OEM). So the only time I will use a cheap Chinese mcor, now, is on my own personal cart.
Having a club car precedent myself, finding your channel has been great. Thanks for taking time to make these videos. Is there a video for testing the MCOR 2 ? I recently picked up my cart from a repair shop after determining the technician was a parts changer that just keep replacing parts until the cart runs again . That’s not my method. Surely there is a way to test resistance on the MCOR to confirm if it is faulty . Thanks
yes I have the original MCOR and today after doing some common sense resistance testing determined the MCOR was not likely my problem . I used the two pin female plug receptacle to determine if the micro switch was activating by turning the potentiometer counter clockwise . I then tested the three pin receptacle for the accelerator function and it also seemed fine by gradually showing a resistance change as the potentiometer was manually turned. After reinstalling the MCOR and solenoid that the previous repair shop claimed to be faulty I found they both worked fine. I found my problem to be a bad control module. Luckily I found a used controller for testing purpose at a different golf cart repair shop. I installed the controller and the cart functioned as it should! I’m now faced with the decision of upgrading the motor and controller for added torque since the controller has to be replaced anyway. I’ve been unhappy with the torque when using on gradual to steep grades. This cart was purchased to use as a quiet and comfortable way to move about while hunting , working and joy riding . The hills have always been an issue even when the cart was new. It is lifted with a rear mounted seat and extra long roof to cover the back seat . For lack of a better description the cart kinda has the look of a Bad Boy buggy minus the camo. I’m also considering changing the 4-12v battery system to 6-8 volt batteries for better capacity. I’m researching now how to modify the battery compartment to accommodate. Thanks for the reply. If I can locate a phone number I may call you later to discuss any options you may have. This is the first actual breakdown I have had on this cart so I am very happy with its reliability. After learning some about the possible upgrades this looks like a good time to figure out the best recipe to better suit my needs from this cart.
Usually when dealing with motors , you need to make a decision if you want speed or torque. Normally when 1 goes up the other goes down. They do have controllers that have adjustable settings on them so you can switch on the fly. But they are pricey.
I have been able to fit 6 batteries in a n older 4 battery precedent before. I ended up cutting rectangular holes in the front of the battery bucket, so the front 2 batteries would protrude into that dead space between the body and the battery bucket.
Hi Wayne, do appreciate your video/ sharing, it is fruitful :) Speaking of MCOR4, the reliability is not good (cars start hesitating/ shaking during acceleration), and I am seriously considering putting MCOR2 through a conversion connector. May I learn any suggestion from you? Thank you in advance for your advice!
Trompie, your mcor is a mcor 1 and it is mounted under the cart, underneath the pedals. The only mcors that are made anymore for your cart, are aftermarket cheap ones. You can find them all over the internet for less than 75.00. The only other solution is a conversion kit, that costs about 300.00. You should be ok for awhile with the aftermarket mcor.
Hey Wayne, great videos! Can you do one on how to detect the problem. For example where do you start first key switch, or f/r button etcetera. I have a 2010 CC precedent
Craig, Are you trying to troubleshoot a precedent ? Do you have a particular issue with your cart ? Or are you asking the sequence of how the voltage travels? Im not sure im following you exactly. Thank you
wayne martin Thanks Wayne, I did the push the cart test and get the beeping sound, I assumed it was the mcor. I replaced my mcor4 with anew one and still nothing. Batteries take a charge, and the buzzer in reverse sounds healthy
First , if the batteries are charged, make sure tow switch is in Run, turn key On, put in Forward, and step down on Go pedal, 3 times! If it does not Run at this point, Then try resetting the OBC. Do this by disconnecting Both the main positive and main negative wires, and let it sit for 10 minutes. After sitting for 10 minutes, hook the wires back up, then go thru the above sequence i layed out. Tell me what happens.
Alan, you wont need an adapter , unless your pedal group is gen 2. Look at the color of the pedals, are they silver or black? Does the gas pedal curve or is it straight?
Hello...mcor prices range from $45-$225 for a 2007 club car precedent. What's your recommendation on which one to buy and where? Thank you. Your awesome!!
Hi David. I'm from Knysna, Western Cape, South Africa and recently bought a previously owned club car. Not sure of model 18780? It is in fairly good condition but when I used it the first, and only time so far, it ran ok but the speed varied quite a bit from relatively fast to very slow. It looks and sounds like the MCOR as per your video. What must I do to remove the old one and can I purchase a new part or conversion kit from you to be sent to SA and at what cost? Regards.Trompie Barnard
I have decided to replace the MCOR 2 on my 2008 Precedent with pedal group 1. I see a big difference in prices of the Chinese while the Mexican part is over twice the money. What are your thoughts?
@@waynemartin.waynesgolfcart4900 Am I stuck. Do I have to try and replace the current system. I looked at your website. Looks like you are very experienced in the golf cart business. My cart is in great shape. Not sure if it would be worth trying to convert to a 48 v system with all new parts to make it work
Am I right to assume my 2018 precedent i2 uses an MCOR 4? I have some hesitation/shuttering at full throttle. My batteries are new, my original curtis controller had the same issue, my new alltrax XCT is having the same issue, I have a brand new solenoid and newer motor. I can't think of what else it can be??? Hopefully I ordered the right part!
Wayne, great video. Got a question. Can you recommend a place on line where I can purchase a “OEM” MCOR 2? Got a friend with a Club Car whose micro switch in the MCOR of a Precedent is bad. Would just replace the switch but not sure if I can get the MCOR open without damaging it. Don’t want China knockoffs. Thanks, Ron Hirsch
yes, buy it from David at Revolution Golf Cars. I buy all my mcors from him. Tell him Wayne in calif sent you! Also, meanwhile unplug the 2 pin connector from the mcor, then bend a paperclip into a u shape, then push the paperclip into the 2 holes in the loose connector. Leave the connector loose then drive cart to see if that helps. By doing that you are by passing the microswitch.
wayne if it’s the switch which I suspect, would you jumper it out and run it that way or is that dangerous? Thanks for the recommendation as to where to buy an OEM. If it was my cart I would just replace the MCOR though the part is pricy. It’s an old cart and putting a lot of money into it would probably be foolish. I am a retired electrical engineer so working on this stuff is fun.
I have a 2013 Precedent gas cart that needs an MCOR. The MCOR 4 doesn't fit, the current wire harness has 1 plug (with 7 prongs) into the MCOR, do I need a conversion kit? The conversion kit doesn't look like it has 1 plug either.
My cart doesn’t really shudder, or hesitate. It intermittently just doesn’t go when I depress the pedal. Nothing. So I just press and release until it finally just takes off. Or I can turn the key off and then on, and that seems to get it operating again. Then it operates normally. One round last year it did this multiple times, then worked fine for many rounds. Then did the same thing a few more times the rest of the year. Very intermittent. Your thoughts on what the culprit may be?
I do not have a video on that. The kit comes with very detailed instructions. It is a fun project, and if you are good with your hands, you shouldn't have trouble.
Hello Sir. I have a 2003 Club Car DS IQ model. You are the only guy that seems to know how to get to the root of issues with electric carts. I replaced my batteries. Soliniod speed control is good. . The cart goes and will stop under load. Like going up a hill. Press the pedal again and she goes.rinse and repeat. I took it to a credible shop and they could not fix it. The Mcore has the upgrade. I’m baffled. Any advice for what to look for next? Have you ever encountered this. Your my last hope. Best, Bruce Johnson
IF your batteries are NEW , not 4 years old, AND you replaced the mcor with a conversion kit, NOT a aftermarket mcor, then that really narrows it down. However my first guess is you replaced the mcor with aftermarket crap, and that is your issue. They no longer make oem mcors for DS carts, so if you buy a replacement mcor, it will be junk. The aftermarket junk wont last longer than a about a year. So i think you are gojng to waste alot time going on circles with this. If your mcor was good, then i would say either a loose connection, ( on motor, or key switch, etc ) or forward reverse switch needs replacing.
@@waynemartin.waynesgolfcart4900 Wayne. I have not replaced the MCor. It evidently had a conversion put in it before I bought it. I had it for 2 years before it started doing this. Is it possible the conversion failed? I ve checked all connection and cleaned. Made sure they are secure.
Yes that sounds like the mcor. One thing to try, is turn the key off, stomp the go pedal to the floor about 10 times. Turn key back on and drive at full throttle and see if it temporarily got better for a minute. If it did, then definitely replace the mcor.
If it won't move at all, it's not the mcor. Either batteries, solenoid, loose or bad connection, tow switch, or the fuse that is back by the controller.
I think I have the same one as you mike please post the part number or a link I can’t find this thing anywhere it’s defiantly not ether of the two he showed
I noticed from trial and error and research. The linkage from my go pedal to the MCOR is sloppy so I figured I’d just replace it all. I did put a rubber washer between the go pedal arm and the little pin it pushes to turn the arm to the MCOR and it helped speed up the cart. Don’t really like it being jerry rigged. Would rather replace the whole damn thing and have it done right.
Alan, it is the mcor. Replace it, and it will fix your problem. The hesitation in an mcor, is the 3 wire side of it, the "swiper, or rheostat" part of it. The intermittent stop and go is the 2 wire part of it, that is the microswitch is failing. Again replace it, and all should be good. Wayne
Thanks Wayne! My Precedent was built the 31st week of 2010. So I’m thinking I should upgrade to the newest Mcor, with the adapter kit? After your video I feel fine just doing it myself. Again, you do a great job of explaining everything in your videos. I think you will gain a strong following, keep at it.
Do you know why the Chinese / Mexican MCOR4's go bad so quickly? I took a hot knife, and disassembled one to find out why. The hesitation/bumping/rough riding/etc. is not a mechanical failure and While not necessarily easy to do, this problem is fixable. After taking the flat topside off the MCOR4 carefully, all you need is a small flat blade and paper towel or small piece of rag.
Good morning Wayne I hope all is well well thus far I've changed my receptacle which I needed to do but we still have a power problem with our Club Car DS model. I had my daughter take it for a ride using my GPS and she got it to about 8 mph, she was on a slight downhill grade and got it up to 12 mph. Reverse is real slow and to try to back up a hill it's like non-existent. So I'm thinking emcor does this sound logical to you? Thank you in advance
I find it almost impossible to tell the difference on the mcor4's. Even when I order them from a club car dealer, they still say "Mexico" on them. Also. they are pretty inexpensive compared to the OEM 2's, so I wouldn't spend alot of effort over it, and just go ahead and buy one.I think I sell both of the 4s, OEM, and aftermarket.
Ok. I load tested all six 8 volts and 2 of them showed bad. I’m pricing new ones now. It seems weird that reverse works normal even with 3 people in the cart, but forward barely moves, just shudders and creeps along.
I need more info. What do you have ? A resistor cart? Vglide? Potentiometer? How old are the batteries? What is or is not the cart doing? How long has the problem been noticed? Describe what is happening?
Trompie. I need to know what model of club car do you have? Is it DS or a Precedent? Is it an electric cart? Please answer, and if you will email me, it will be easier to communicate. Wayne lemwert@sbcglobal.net

When my pedal reaches full throttle the electric motor cuts off and on. Would this be my MCOR worn at top throttle? Mid throttle works fine.

Only would need to go to the conversion kit, when your mcor 1 fails.
I noticed from trial and error and research. The linkage from my go pedal to the MCOR is sloppy so I figured I’d just replace it all.

Do you know why the Chinese / Mexican MCOR4's go bad so quickly? I took a hot knife, and disassembled one to find out why.

Any idea if the MCOR4's off amazon are worth a poop? I had a hard time finding OEM

There really is no such thing as a code 5, that is not true.
Call any dealer and they can hook you up with code 4.
I hate to disagree, but Club Car's first carts were not the DS. I have a 79 Club Car Caroche which pre-dates the DS.
are the mcor the same on a carryall 500 2015?
yes if it is an electric cart.
Ds hill brake repair video .
How can I test to see if my mcor 1 is bad on my 2002 48v DS?
You should be able to tell when you step on the go pedal.
Does the car move right away.
Do you feel any hesitation at any point when pedal is pushed?
It shudders in forward when I step on the pedal. But in reverse it runs fine when stepping on the pedal.
sounds like a battery problem
Ok. I load tested all six 8 volts and 2 of them showed bad. I’m pricing new ones now. It seems weird that reverse works normal even with 3 people in the cart, but forward barely moves, just shudders and creeps along.
reverse is half speed, only uses half the voltage
What is the mcor4 part #
The oem part number for an mcor 4 is :
105116301
Where is the MCOR located on a 94 club car?
Is it a 48 volt cart?
@@waynemartin.waynesgolfcart4900 36 volt
You don't have one. Only on 48 volt
@@waynemartin.waynesgolfcart4900 Thanks, having symptoms of a bad MCOR. Any ideas?
I need more info. What do you have ? A resistor cart? Vglide? Potentiometer? How old are the batteries? What is or is not the cart doing? How long has the problem been noticed?
Describe what is happening?
Sorry Wayne. Don't know where the David came from, Trompie

Trompie. I need to know what model of club car do you have?
Is it DS or a Precedent?
Is it an electric cart?
Please answer, and if you will email me, it will be easier to communicate.
