I got my car out for the first time in about a year. Its a 93 lx. And I had a charging issue so I pulled the alternator and it tested bad so I replaced it. Got the new one on and it still had a low reading on the gauge. O I turned the headlights on to see if the gauge would drop and it pegged so far down I couldn't see it any more. The temp gauge pegged way of past the top of the gauge and the tach dropped to pointing straight down. Turn the lights off and it all goes back too normal but low. Last year the firewall starter selenoid went bad and was causing the starter to run after the engine started. I replaced it and the starter and it fixed that problem. Any ideas?
