Resistive load bank only load test the engine, not the generator. It takes verry little excitation to make rated voltage no power factor. Put 8% lag load and you will see the nameplate excitation. I worked for Michigan Cat for 43 years as a E P G Field tec. Those things are bullet profe. But you should see about 12 volts no load @ reted voltage to make sure all is good in the excitation system. Glad you are back.
Hey Mike, Good to see you posting again! Always enjoy watching you put those big gensets through their paces! I'm already looking forward to the next one!
Inductive Load bank. These are reacter equipped and expensive and much larger then a restive load bank, but we'll load the engine and generator. I have had generators with a bad roter that tested good with on load bank test, but would not start the motors in his saw mill.
Good to see you, Mike! Excellent presentation here. Always enjoy your videos. Recently retired from 36 years Operating Engineer at a major OKC hospital. We ran mostly Waukesha Pearce units, Onan's and a few Cats, for a total of 7,500 KW. Was exciting work, HOT, but exciting. I miss it already! Will be watching for your next presentation.
It's good to see you again! And, it's good to see that you can get replacements for obsolete electronics on these machines. I must say, it's an impressive result, and considering the load that's being switched on and off, that engine barely flinched at all. That's going to be a good genset for someone.
Nice to have you back. Sometimes life just gets in the way. Your knowledge of the voltage control circuitry and substitute regulation systems is mighty impressive.
Glad you're back, Mike. Happy new year. Looking forward to more great work in 2023. Looks like you've got the old Cat genset all straightened out. Also I always love the cleanliness of your wiring.
Im currently doing a full controller upgrade on an old 60kw Generac, went up in smoke on me during a diagnoses for no remote start. The entire generator control harness was melted and fused together. It needed a new governor controller and actuator, as the original Generac stepper motor needed inputs from the original control module, which is obsolete. So I have a new deep sea controller installed, engine running at 60hz, and the next step is to get the new Generac AVR working. It also requires ballast resistors, and in the schematic it shows a rectifier in the field circuit as well, so Im assuming the AVR does not put out a straight DC voltage for the field.
The other commenters have said it well and I too, have certainly missed you interesting videos. This one is no exception with this new regulator installation and run up. I was looking at the exhaust stack to see what colour the smoke was, looks good now, as you pointed out. That CAT seems to be healthy and is up to the work. I am mostly looking forward to when you can get back to your big CAT Gen-Set, I was very interested in that work. Time is precious I know, as you pointed out here, you are "on the clock". I'd say this customer is getting his money's worth if you're on the job. Thanks for this one!
Great to see your back, I was getting kinda worried you were well. I watch James Condon every week and got your link from his recommendations . More videos soon I hope. Many thanks Tony Quinn.
Basslet are very good regulators. I replaced an old contact point regulator to a new modern Bassler. The Genset I was working on was a 6 clynder Detroit 2 cycle diesel. Wire for 480 volt 3 phase. It originally would only run one 75 hp well motor. There were 3 wells at this site. After I installed and adjusted the Bassler I was able to start one at a time and get all three well motors to stay running. These were used at my old job working for the Suffolk County water Authority on Long Island. Management was thrilled to get full emergency power back.
Very nice wiring job! Very neat clean transition! Shoutout to John Dean who I worked with at Mi Cat for 30 years. John is one of the brightest electronics Tech I have ever run into. The 3306 engine was one of the best and simplest engines Cat ever made.( before the government got involved with emissions.) That electro mechanical Redco control panel still going strong after being around since the 70’s. Hope all is well John! H. Lyle Ocala Fl.
G'day, Mike! Happy New Year to you, and your family, too! Hope you know, it's very good to see you! We all have missed you! By the way... Enjoyed the video!! I really appreciate your wonderful expertise and knowledge! (Cat VR1 voltage regulator replacement, with a new Basler AVC63-12) Thank you! 'Well done!!' Cheers! ❤🛠✌🏻😊
Hey Mike, welcome back! I don't understand anything about electronics or generators but I enjoy watching you troubleshoot and retrofit these old machines. Hope to see you again at the show this summer.
Your distorted voice, caused by overpressured microphone membrane and mixed with powerful cat roaring, is just wonderful combination of your enthusiasm and brute force of big combustion engine. Thank you, for another interesting video. Best regards from viewer from the other side of the globe.
GOOD fix! Sweet genset. I was arond that engine in D6-C' and 7-F's. Fine setup and it has the hand throttle like the old genset the crusher had with a D-8 or 9 pony start engine. Slow speed but STRONG! Glad you're back!
Just found your channel, i'm almost 2 years into my career in the genset maintainence/repair field so your channel is a nice resource! I'm much more comfortable with the mechanical side of things rather than the electrical and i always have been, but i hope that changes with time, watching your videos will certainly help haha. Super tidy job with the wiring, love to see it 🙌👌
Worked on wellhead gens and compressors. So many 3306 out in the oilfields. We would top end em at 30k and inframe at 60k. They usually lasted 80-95k before being swung and rebuilt.
I was wondering if you had already posted a video of an AVR retrofit. What a coincidence that you posted this one today. Thank you for the new video, it was just what I wanted to see!
Impressive and interesting as ever. I think I would have used all the mounting screws on those metal clad resistors rather than one each as far as I could see, their full rating only applies when fully bolted down to a defined heat-sink.
Hi Mike, sure good to see ya again!!! Hope there will be some more from you shortly. Whatever your circumstances, keep up the great work!!! Thanks for the great content!!! I've always enjoyed your efforts. I did 30 years with the phone company doing their power and battery plants, so I love to watch your projects and see you save some of these old machines.
Friend of mine fitted a 500 kva ex military trailer generator at a farm grain drier it was 1955 vintage with 50 hours, was cheaper than the line charge for the install that was 15 years ago, just needs it's oil changed every year before it's started for the harvest
Excellent video as always. I just snagged some DJI wireless mics, check them out they might fit your needs. As for the video, the info in this video couldn't come at a better time for some of us. 😁 Glad to see you're back.
Hey Mike, it is great to have you post a vid again and as usual, a great vid. Glad to see you back, thanks for your efforts as we all love to be your apprentices, looking over your shoulder.
😃 Hey!! Mike, it's great to see you post again! I think I've watched most of your vids 5 times! I typed this even before watching your new vid. 😆 Gonna go watch it now. Anyway, great to see you back. Ken G.
Recently discovered your channel. Really great content on some heavy iron! Thanks! Hoping to see a future video on that old Onan you grabbed from the farm!
Great to see you back again, I am sure I am not alone in my thoughts, missed your excellent content. So awesome to see 10K views in 1 day. The numbers do not lie.
It was there for suppression. The power block has a SCR, and a diode. The diode is an exciter field suppression diode that maintains the field through the next 2 cycles after the S C R is fired.
@@johndean7618 thanks for the explanation of the function of the diode. My surprise is because i've not seen any equipment built in the 70's or later that used selenium rectifiers, after silicon diodes were in mass production.
You need the connector and the software. Takes like 10 mins to set up an AVR. Looks good tho. Did a deep sea AVR, comap controller, and GAC governor. It's satisfying to give older gens new life.

But you should see about 12 volts no load @ reted voltage to make sure all is good in the excitation system. Glad you are back.
How is the non-resistive load created?
You need some reactance, so either inductors or capacitors. If memory serves you’d need an inductive load to make a lagging load.
What do you mean 8% lag load will make excitation volt?@sstorholm

good to see you back agen mike, intersting vid,, thank you. regards richard.
Great to see you back! Can't wait till the next project.
Glad to see you back online, hope everything’s been ok!
It Is so comfortiable To Watch this video when someone knowes what their talking about . You are the best. Mike Makowsky

That was great! It's always good to see someone who knows what they're doing working on these machines.
Glad you're back Mike....from another Mike LOL. That CAT's not even breaking a sweat and sounds great. Great explanations as always.
good to see a new video, your wiring is always good looking
Careful with fuses in the sensing lines, if one of them blows voltage will go up until smoke comes out everywhere, lots of collateral damage.
Correct. They are internally fused also.
Nice to have you back. Sometimes life just gets in the way. Your knowledge of the voltage control circuitry and substitute regulation systems is mighty impressive.
Thanks for checking it out Paul!
Missed yer buddy! All best to You and Your family for 2023, Great vid as per usual
Wow! I was just thinking, just 2 hours ago, that Mike hasn't put out a video in some time. Awesome.
My favorite channel! You deserve a lot more subs.
Beautiful workmanship in that panel.
UK Glad to see you. as long as your OK that's what matters most.
good to see you back

@@montey1017 So perfect so simple.
I hate the heui POS motors 3126 C7 s .
CAT went down hill now sells Chinese parts at dealership.
Sad .
Hey Mike welcome back fella .. we all got a little worried that we were gonna lose ANOTHER great channel!!
Looking forward to the next video

I always enjoy your videos, and wish I had your knowledge of these old gensets.
Good to see you back. I do love your videos. They are so informative.
Mike, great to see your back. Hope all is well and look forward to more vidios.
Welcome back! Enjoyed the video. Nice wiring job on the new regulator wiring. If it looks good it will work good.
It's been a while. Thanks for posting another video, they're always enjoyable.
Hey Mike, it is great to have you post a vid again and as usual, a great vid. Glad to see you back, thanks for your efforts as we all love to be your apprentices, looking over your shoulder.
