generator 24 coupe

Post by Barteldes » Mon Mar 13, 2023 4:59 pm

First time T owner and learning one lesson at a time. I am overwhelmed at how nice and helpful you all are. Was getting no reading on my ammeter so i watched youtube videos and found one guy "flivver" channel. Good videos, really smart guy. 3 part series on the Gen and cut off. im sure you all know him, he seems deeply rooted in the community. i tested the cut off (while on the car) and got nowhere. Because i think the generator wasnt working at all. i Jumped the generator as he or maybe another video suggested to get some magnetism back and now the gauge actually moves but you have to tap it some. it sticks (the gauge that is) The gauge is not reliable enough to see if the cut off is working right so ill take it off and bench test it. I cant adjust the third brush until i know what i have. this guy tested with a little meter ( i have one) but he had this power source that he turned a dial and fed it power so he could see when the points opened and closed.. what the heck is that power source device? where do you get one? It looked like a fancy battery charger but none like ive ever seen. i have a lot more to say but i think ive exposed enough ignorance for one post. ill keep them coming since there's lots to do with this car and im just learning.. i'm calling it Livingston BTW (it looks gentlemanly)

I would suggest that you obtain the book "electrical System" published by the club. It has a section on the generator and wiring. This is good for the original system. It is not correct if you have an alternator or a voltage regulator, but with the original system it is very well written for a do it yourselfer.
Take a look at your ammeter. When you turn on the lights without the engine running, the ammeter should read discharge around 10 amps. Turn off the lights and start your engine. At idle it should read zero. When you rev the engine, the ammeter should read charge. And if you have it running and turn on the lights the ammeter would either read zero or possibly discharge but not as much discharge as lights on without the engine running.
The rate of charge is adjusted by moving the third brush. To charge more move it toward the engine and to charge less move it away from the engine. A very small move makes a big difference in the charge rate. So if you do most or all your driving with the lights on, adjust to about 10 amps, but if mostly with the lights off, set for 3-5 amps. this should be enough to maintain the charge while driving and short distances with lights on.

The device you described is moat likely a variable DC voltage power supply. He was checking at what voltage the mechanical cutout points close.
I use a cutout on my car which I have successfuly adjusted with flashlight batteries as well as a power supply. I don't recommend doing this.

The trouble free way is to use a diode cutout if you continue to use a generator. Eben more trouble free is to use an alternator instead of the generator. This eliminates the cutout and all the issues with it and thr generator.
