Delco 10si, 12si Alternator Voltage Regulator Testing - zeketheantiquefreak

- With a variable voltage DC power source (adjustable from at least 13 to 16 VDC) and a 12VDC bulb socket with pigtails, (or a simple test light) you can easily test these durable voltage regulators. Cutout should occur at ~14.8 VDC.
Do you plan on posting any more videos?
how to determine , do I have pushrod tick, rocker arm or valve lifter ticking ?
Thanks
Thanks for this info, great help! Will this work for "1 wire" VRs as well?
Sorry, no. I tried to 'crack' the mystery of the one wire, (rev up the engine to self-excite the alternator) and failed. I don't know how they work and would appreciate testing info on these. Thanks for the comment.
Sir is there any posibility that I culd manuali control when and how much that voltage regulator wuld charge me baterry???
I have unusual problems many times I use hv ceramic capacitors on me ignition coil so me alternator is constantly back feading true alternator buld unless I give it bigger engine rpm also I have problems when running centrain engine aplications I go as low as 300-500rpm with me engine Its Opel engine typical GM lay out systems.
So I try to figure out when useing plasma ignition or amplifier ignition to not mess up me charging system or I wuld like to control me alternator charging manuali if posibel.
So do there exist any circuets that I culd use to fix that problem some peopel mentioned voltage deviders some say cloosed loop regulation systems Im realy confused honestly .
So hoppe to see advice what I culd do to make at least some what that thing manuali programabel.
Let me think on this for a day or so... A 'backfeed' problem is usually corrected with a diode at terminal 2.
@@zeketheantiquefreak8518 I will be honest with you.
Some of those effects are great for fuel economi and engine power.
Me alternator pin 1 is bulb pin 2 sense is bend inside the case of the alternator .
There is diode in the dashboard but its conected to engine warning light who isnt even used .
Besides the alternator I have other unusual effect who acure in different event like self acelerating carburetor metalic springs get contrapted that happened due to blinker relay I found out the back side bulb holder who has dual filament bulbs they all share common ground wire the wire was green corroded and black wire on me key switch started to burn tge effect was engine dont want to shut off when all 4 blinkers are engaged the engine worked in union with the blinker relay when the key is of .
The self acelerating effect at full engine trothel Is seperate acurance I suspect xenon bulbs and the rear heater defroster relay 4pin who is leaking current over night so I removed it and I removed the air filter and blowby hose the self aceleration stoped .
I honestly dont know all me relays are ic chip based they have internal resistors and diodes but still they interact with dual filament bulbs,xenon bulbs and back charging alternator.
And I dont know how to fix that problem.
I did yesturday dump all me wire harnest out and found broke wire for door switch was damaged .
The problem is many of me relays share common - and + connections and lot fuses .
So they act identical to dual 5 pin relays basicaly or interact some how with ignition coil or xenon bulbs.
Thats what I culd discover.
Some how some where those xenon bulb act nearly identical to wacum tubes becauseI suspect the 4 pin relay is leaky and the heater element in me rear windscreen look like gride element for wacum tube .
All those effects are strange and some are usefull for exampel that blinker relay can be used as buzz coil so me engine can work with out the 4pin gm ignition module.
And the engine it self starts to act like Hit and Miss engine.
The xenon bulb deal self acelerating was also interesting to me because I might culd use that to regulate me E Core type ignition coil like dimmer switch circuet because the original 4pin gm ignition module does not have relarding option.
So perhaps you might quesed I have cold start problems in winter I like to drive me engine more advanced because of low rpm and fuel economi.
I have video on me chanel proveing gasoline engine diseling.
So yes the diode is bypaased for the alterbator but still the regulator is conected to the ground side .
So I try to make seperate circuets and perhaps some how control those odd effects .
I have mostly hella relays 2 3 4 6 pin relays. So the problem is I dono where to put diodes even If I have any they have internal diode but still they leak some how .
I dono if zener or shotky diodes wuld help but I dont know what value of diode to use honestly.
No wonder that I am confused so thats why I try to finde older peopel who know about those odd effects that acure on old cars me Opel Ascona C has evry thing tipical 80s GM car has .
I honestly dont know where the ignition power comes from true the dash I supose Im not shure me self if positive linear voltage regulators can back fead as well.
So I took apart wire harnest and found broke wires for hande brake and door switches perhaps that caused problems to .
Normali if I leave in reverse gear or hande brake on the baterry drains some what faster.
Thank you trying to help me.
Me head hurts from so much trobel with that engine.
@@MechanicForGMCCars I will leave these comments up in that hope that someone will have the answers for you. It is above my skill/comprehension level. Thank you for the comments.
@@zeketheantiquefreak8518 thank you
How wouod u bypass one of these? I need to charge my 4 truck batteries so i can keep driving. I would be happy with 16volts, i would just turn on all my lights to keep from frying my ecu
On the back of the alternator, there is a small (half-moon?) hole on the edge near the two wire connector. Inside is a metal tab, part of the regulator or brush holder. When this tab is grounded, the circuit is 'full fielded'. This is used for temporary testing/diagnosis purposes and the voltage is dependent on rpm... Watch the voltage very carefully, a rpm/voltage spike can be the 'angel of death' for your bulbs and electronics.
Hey there Zek, Don here again, have you ever done a 12v negative ground conversion from a 24v positive ground on a 20 series JD ?
It is a very involved process due to the 'split system' of the 24 volt JD's, of which I am most familiar with the 4020's. Cost is prohibitive needing a 12v replacement starter and, say, a Delco 10 or 12si alternator. Yes, you can do it, but arm yourself with as much knowledge about the split system as you can before proceeding. Even though the starter is a DC motor, it generally won't change direction when switched to a negative ground. Ask around. Watch as many videos as you can find. Good luck with your project and let me know how you are making out.
I’ve watched this video several times and it is informative, however!!!!!!! Why can’t you move the camera your using to make the video further away from the parts you’re filming so you can see what the hell you’re doing. All I see is your fingers and the camera moving to quickly to see what you’re doing!!!!!
My apologies.
