Hey guys, so when my truck is running, all the lights that I have on the truck will sort of "pulse". I had a buddy tell me it might be my alternator regulator? Its done it for a while, and now I think its time to fix it. Any body know what it might be and how to fix it? Thanks

Mine will randomly do that when my alternator gets wet. How often is it pulsing? Is it like once every 5 minutes or once every week?

On my capri, they did that. The ground from block to frame was disconnected

Did you ever find out what the problem was? I am having the same issue. Checked grounds. Had alternator tested. It was good. Replaced it anyway. No luck. My alt is also putting out over 15v at an idle.
