Low voltage to battery

Postby wcfkeith » Wed Jul 27, 2011 10:31 am



I tested all three legs from the stator, no shorts to ground and all three have continunity with each other. However, when I check the ac voltage I'm only getting 3.0 - 4.0 volts on the three legs. Anyone ever hear of this ? It's supposed to read 30 - 40 ac volts but all three legs reading 1/10 th the normal value (and yes I checked the meter) any ideas ?

Read the voltage between any 2 of the 3 wires not to ground.There are 3 measurements taken at 3000 rpm. here's a pix.

Your readings really sound suspicious, I could see a burnt out winding giving only 3 volts, but it would be really surprising for all 3 to burn out and give 3 to 4 volts. You did have the voltmeter on AC voltage not DC? How did you measure the voltage, where the coils unplugged from the rectifier/regulator?

If after testing you find that the stator is shot and you dont want to pull the engine to fix it you could do a Poor-boy type of conversion. I run a 55amp car alternator on my 82, it gives me all the power for extra lights I could ever want.If interested here is the link to another forum where I posted how I did it.
