Here is a question, what if I'm not getting voltage from my blue "charge now" wire? What do I do then? I've replaced the connections on all the wires but its still the original wire. Prior to my old 65 amp (i just bought a 90) breaking the battery diode would very dimly glow and sometimes come on periodically. I'm going to go re-clean all the contacts I think. Paying special attention to the grounds...
The very faint alternator light glow that you can see on a dark night is caused by the alternator path to ground not being a perfect conductor compared to the the rest of your electrical system. I don't believe it's a problem but perhaps you could directly ground the alternator anyway.
