Nope that wasn't it.
I have no power coming from the alternator on the green 403 wire that goes to the hour meter. I did unplug the harness from the alternator and jumped power to the green wire and the hour meter does work, but if I plug it into the alternator I get no power on the green wire.
I have battery power on the purple wire there and then I get voltage on the yellow wire when I crank it but none on the green wire. The yellow wire goes to the charging light which was burnt out but I replaced it and it works now.
I just replaced that alternator with a Cat reman last Saturday. Hour meter wasn't working before that either.
There's a connector that the yellow wire runs through...I have power on both sides of it with a digital volt meter, but not with a test light. However, I think that's because I'm providing a ground to the lamp when I use the test light which energizes the lamp circuit. I think that yellow wire is a neutral from the alternator except when running which energizes it and makes the lamp go out. So I don't think a test light will tell me anything since it acts both ways.
I have checked output on the green wire with the engine running with both the DVM and the test light and get nothing.
