i swaped out the ammeter for a voltmeter(63). I transplanted the circuit board from my guage cluster to the cut up new cluster. I put it all back together and nothing. I went back and read posts and cleaned up the copper contacts (with an eraser) reinstalled and now the guages would peg to the right. Both gas and temp, but if i unhook the temp wire from the sender , then only the gas guage wants to peg. Now does this mean that another open ground is still stopping me. what causes this?

It sounds like the instrument regulator is putting out too much voltage. It should be pulsing about 5-6 volts. On the 63 the regulator is inside the fuel gauge, which is a pain to fix. You need to put a voltmeter on the middle of the three terminals of the fuel gauge to see what the output voltage is.
