Testing Gernerator
 

My favorite car is a '51 Ford that is bone stock (6 volt positive ground). With the engine running the amp gauge doesn't move one way or the other when rpm's increased. When the head light are turned on it shows a discharge. I would like to test the generator by itself. If memory serves be correctly there is a way to "motor" the generator, without the belt attached, to verify that it is working. How is that done? Any suggestions appreciated.

Have you done a search on this site? I plugged in "motor generator" and got lots of info.

Ground to housing and bat to field and armature and you get a motor.

,start engine, pull + terminal off battery, if engine dies generator is bad, if engine keeps running regulator is bad, no need to pull gen or fan belt till you find which one is bad

Re: Testing Gernerator
 

If the car is negative ground, do you remove the - terminal for this test?

RWG,
Motoring is a test and a good one but does not tell the whole story.
