Everytime I put my right signal on, my tach, volts and oil pressure gauges go out. Took it apart but couldn't find a problem...plus when I turn on the cluster lights it does it....Anyone ever had this problem?

 

i have a similar problem. when i turn my dash lights on everything just peeks or drops all the way down. my rpms peek. my volts drop and gas gauge doesnt work. And also my right turn signal always wants to stay on?I wish i could help you to fix the problem but im still trying to figure it out myself. if you or anyone has some advice that would be great!

 

check the ground strap from the firewall to the motor

 

Where is that located?

 

Mine does the same thing except my fuel gauge isn't affected. Right blinker light just stays on..

 

if you look right above your distributer on the firewall the should be a bolt screwed in the fire wall with a braided wire attached to it thats the ground wire it goes from the firewall to the back of the engine good luck !

 

behind the distributor, its a bare braided flat wire that goes from the fire wall to the block or intake bolt

 

I have a similar issue where when i turn my car on, my volts gauge is bouncing up and down in the middle of the gauge, my gas is off my a 1/4 of a tank, and my temperature gauge is pinned at the bottom. I've just decided to change the sensors.

 

I said the hell with it and just changed the gauges, a little pricy but damn looks good. A black piece of lexan, some hole saws, and some home work tracing wires. Works no diming of lights no gas gauge sticking
