I turn the headlights on and all of the gauges go to zero. Why? Oh, it is an 85 Blazer.
Sounds like a short in the switch, replace.
Possibly bad ground??
Your going to get alot of guesses with a question like that, we need some mo' details please...
grounding problem... add a ground from your battery's negative post to the chassis... ie a body panel... or the front radiator support
I'll give it a shot. I had the dash out and put it back in when I noticed the problem. It is plug in and not too much to screw up so I don't know what happened. I just put this new engine in and have not hooked up a chasis ground yet.
With a hooked wire connected to the batt. negative,you can touch the gauges negative connection.If the pointer goes to her correct position,you knows wath is the trouble.A bad ground connection.
Figured it out. I am a retard. The connection for the dash was loose. I thought I plugged it in till it clicked. I hated to tear it back apart, but nothing was working. Thanks all for the advice.
