Larry,
There are a number of things to check on the dash regulator.
First, it must be grounded to work properly.
Second, if the two wires connected to it are reversed the gauges will
move up, then drop to zero and stay there. If they are connected
correctly the gauges will slowly move up and possibly drop a bit, but
not to zero.
If you have a volt meter you can connect it from ground to the
yellow/red wire. It should be pulsing from zero to battery voltage. If
it is staying at zero, the wires are probably reversed. The black/white
wire should have battery voltage on it. These readings are with the key on.
The regulator should have a "b" stamped into the plastic bottom plate ,
next to one of the lugs. That is the lug where the Black/White wire
goes. (This is by memory, but I do recall that one of the lugs is marked
and I think it is the one that gets powered.
Let me know if I can be of any further help.
Peace,
Pat
