alternator malfunctioning?
I was driving around today, and I noticed that all the idiot lights turned on. But all the idiot lights were really dim, I could barely see them, and if I gassed it even a little bit, all the lights would go away. But if I cruise in neutral or am stopped, the lights would come back on.
I've got an 89 N/A, battery is 1 year old, alternator is an FD alternator I got off silverrotor about 6 months ago, and the belt is new cause I needed a longer belt for the FD alternator. So most of the stuff is new, I don't see it malfunctioning.
At first I thought maybe the belt was slipping, but if that was the case, the idiot lights should come on when my engine is working harder. Am I right about this?
My guess is that it's my grounding. I've noticed that my dash voltmeter significantly drops when I have a lot of electricals on (ie. heater, wipers, lights, etc). I've been meaning to replace the grounds, or at least add new ones in, but i haven't had the time to.
So my question is, could poor grounding be the cause of the idiot lights going on, or is this most likely an alternator malfunction?
