Were is the Ground for Interment cluster
my temp & Gas guage read off then back to normal after I hit the dash
and the radio is off station when this happens

It is common for the 'ground' to fail on the instrument panel PCB on 86-88 models. My '86 was afflicted with this. however, if the ground goes then the tacho and time clock usually fail or intermittently cease to function. This can be remedied by running a custom earth lead from the body of the time clock to a suitable eart point.
No siree, I think it more likely that your voltage regulator/stabiliser thingy could be at fault.

Good luck,

Big Rich.

Yes the clock dies also tht why i think it the ground. As soon as this happens
the radio will act as if it will not bring in the station and if i turn up the fan setting it gets a little worst

The ground is through pin 34 in the half moon shaped connector.

The gas and temp gauges have a separate voltage regulator. It can go on the fritz and I think it can be repaired. Look in the 700/900 FAQ section.

Good Luck,Bob

but if the ground goes so does the gas and temp right ?
also when this happens the clock stops and the speedo act a little ifie
it will read normal but at a stop a little forward movement will make it spike
Now when the all in normal the the speedo, clock, gas, temp, radio, act as it should.
