Re: Charging system warning light

Mine does the same, and I replaced the alternator and regulator with no luck. I was told here the white wire from the alternator is the one that senses current flow and should be checked for a good connection to the alternator.

I finally learned to ignore it and I'll probably yank the bulb next time I have access. My digital volt meter says I'm putting out 14.3 Volts, so I'm not concerned.

Re: Charging system warning light

Mine has done that twice. Both times it was an easy fix, pull the electrical connectors off, spray contact cleaner on both sides, reassemble.

Re: Charging system warning light

take it to a reg rebuild shop near you--should end your problem--theres a whole lot of bad rebuilders out there supplying the major chains--your hometown guy will normally do it right----
