Delco alternator charging then not?

Andrew Z · Jun 9, 2008

I have a delco 10 SI, and it used to charge by the one wire method, then it stopped working all of a sudden. Took it off and brought it to be checked turns out that it is fine. put it back on and the only way that i can get it charge is by grounding out the "R" terminal. then it pegs the amp meter right out... charges 14 volts. but if i shut it off then do it again it will not self excite i have to ground out that terminal for a second again. Do i have a bad ground to the tractor thats all i can thing of I have 3 other tractors set up like this and they all work fine, not sure whats up with this one though....

Thanks for the advice!!

Thats one of the reasons why the 3 wire set up it by far a better set up. In the years past I used the 1 wires but NEVER ever again

If the ground was bad it would not charge when it finally does. The regulator is probably bad. Why not swap the regulator for a three wire setup and rock on. JimN
