I ran a new hot wire ( accessory ) to the voltage regulator on black yellow, and now its charging just like its suppose to, i evidentally have a short somewhere in the old one, which i'll be looking for . thanks for the advise and wisdom.
Thats not what i'm getting.... and have checked fuses and wires. the white green or F pin on alternator is like a ground, when i check it from positive it completes circuit, and when i put 12v+ to it it makes a spark.... not good sign... thats what i'm trying to figure out.. Maybe my new...
I really dont understand the wiring on the altenator, is there suppose to be a positive feed going through the plug to the voltage regulator or just negetive ??? :meh:
I have a 77 fj40 and the alternator stopped charging, i replaced with new one and still no luck, i'm thinking may be voltage regulator, or a wire, how can i bypass or test my regulator or troubleshoot my alternator, had it tested and its working on the machine.
