i have a 92 rs 25th anniversary with a swapped 383 stroker. im having problems with the speedo, fuel, and engine temp. speedo doesnt work at all the fuel stays inbetween E and 1/4 even when full and the temp goes nuts!
any suggestions?

 

I have the same thing going on with my 1980 Z28. My plan was to change all the fuses bulbs etc. Also check to see if wires had broken off contacts. If so sodder them back in. I heard if you have a bulb out or a connection problem. It affects the circuit and will affect the charging of the Alt. So that's what my weekend looks like. Wish I was going out cruising. ;(
