Sorry for asking one that I'm sure has been answered before. Searched but couldn't find a thread that sounded quite like my issue. Getting ready for a track day next week, and of course having charging issues. Typically I see the alt light come on with ignition on, but it shuts off as soon as I start the car. Occasionally it does come on when I turn the ignition on, but the next time it doesn't. Now, it doesn't come on when the ignition is on or when it's running. I suspect it isn't charging regardless because I see 12.2 volts with the car off and about the same while it's running. The car has been sitting but it was charging prior to this and it was covered with one of Perry's excellent covers. I wonder if the brushes are bad, but I think it sounds more like a bad relay board.

Thanks guys! Man, when Spoke starts commenting, I know things are serious, electrically-speaking.
Actually, was able to isolate it down to the wiring at the gauges last night. Bulb is lighting intermittently when the ignition is on if I wiggle stuff. Now just have to brave the heat this evening and clean all the connections. I suspect a bad ground, or in this case, power since they are daisy-chained from one gauge to another. |
