Generator
About to check out my Gen, but first. How do you check the out put of the gen, and where would I find the adjustment for the 3rd brush ? this is on my early 30 45B. Oh thinking about it, is there a gap messurement for that cut out under that cap ??

Re: Generator
Open cutout contact gap should be about .020".
Jump the two cutout terminals for one second to polarize the generator, then start the car. Clip the + meter lead to a good ground and the - lead to the generator output stud. At fast idle you should have just over battery voltage, which was checked with the engine off. Last edited by Tom Wesenberg; 11-26-2011 at 03:30 AM. |

For the cutout gap I don't recall. If it is charging when running and not discharging when everything is off, leave it alone. It is to keep the generator from motoring when the engine is stopped. |

Re: Generator
This test will tell you if the genny is dead or not, apply voltage to it and if it runs like a motor it should work as a generator.

Re: Generator
Hook it up to a battery (remember, it's plus+ ground) it should run like an electric motor. If it does, it's good. If it doesn't, it's "rebuildable".

Re: Generator
Install it on the car an check the amp meter or run the voltage sniff like described earlier. Or you can run a small electric motor and a short belt to see if it generates off the car. But if the generator motors it means it will either work or need rebuilt, in other words its worth your effort.

Re: Generator
You may need to repolarize the generator for it to generate. when bench testing with a battery or battery charger, you will need to ground the housing of the generator with the positive cable and touch the negative cable to the generator post, if not you will reverse the polarity. The generator will motor either way but if tested backwards the polarity will be reversed and the generator will NOT charge when reinstalled on the car.

Re: Generator
I do know it worked when I took it out but now the motor is out of the car and wont be back in the car for a long time. But I want to check the starter and gen before I put every thing back in so if any thing don't work I can fix it now. Instead of doing it when I want to drive the car when every thing is done and painted. reggiedog

Re: Generator
Even if they do work now, now is the time to restore them. Take them apart, check the brushes, commutator, and bearings. Clean and repaint as needed. Now you will have a generator and starter that you know will work for a long time. Otherwise you are driveing an unkown and never know when it will quit.
