How to check my generator

Here's a picture that I think Tom posted before that may help.

Thanks Bob this picture is very helpful. Will order some parts to try to get it going.

Thanks Mike, the reason I was only seeing two wires to the generator was because the previous owner attached the light wire with the horn wire so that only one wire connects to the generator.

Bob if I understand this picture correctly EVR replaces the third brush? and if so where does the generator output terminal wire attach? Also where does the third brush wire attach? Would Tom happen to have a picture of the EVR assembled in the case to get an idea of what needs to be replaced and not buy extra parts I don't need.

72 and counting.
It would be so smooth and trouble free to send your genny to Tom for him to work his magic, then all you have to do is install it. No worries about burning up new or old parts from cross connections, etc

I believe that attaches to his EVR... I put two in but it's been a while

Wouldn't that defeat the purpose of this forum, that is to learn about the Model A and how to fix it?

See the picture in #69. The adjustable brush and it's holder are removed, then the adjustable brush wire is attached to the brass screw on the aluminum angle of the heat sink. The wire on the EVR and the generator post wire are both attached to the insulated output brush.

Thanks CHL didn't want to be the one to let him know that we are all learning and this will help the next person that is a rookie like me than comes to this problem.

Thanks Tom for all of your responses, I have learned so much from all of your explanations. thanks for taking the time to teach us about these beautiful cars so that we can keep them on the road longer. I would like to buy a EVR from you ill PM you

Good show D's31..
Don't ever hesitate to ask...we are all learning

 

[tbirdtbird]

once again the point was missed

No, we got your point, you just left it out of your reply...

"72 and counting."

There's nothing wrong with someone wanting to fix it themselves, and using this forum as a resource.

Will be of the same opinion still

Why not try and help the guy like Tom does instead of being so negative?

I tested the generator with the band off to make sure it was in working conditions and when I put power to the top screw nothing happened. I then gave it direct power to the inside of the generator wire and it turned slowly. I took the generator off the car and this is what I found in the inside of the generator. What do you guys think? Time for a rebuilt?

D's31, looking again at your photo in your post #41 it appears that some solder was thrown from some of the commutator bars. That happens when the generator gets overheated, which can happen if the cutout isn't working right. I think that is what happened here. Unfortunately when that happens the generator is pretty well shot and has to be replaced.
So when you put on a new cutout it probably won't change anything.
I have added the photo again with a white arrow pointing to what looks like a few thrown solder joints.
Maybe some other guys can chime in here with their opinion too.
