none of my gauges are working.

thank you for taking time to help me with a thorough explanation. Here's what I know


IS the cluster actually getting GOOD 12V power? Yes All lights on the PC are working since I replaced all the bulbs.

The cluster connector may be loose/ corroded
I pulled it cleaned it and pushed it back on

The pin(s) on the cluster PC board may be loose / corroded
they felt solid

The brass spring fingers which the instrument regulator plugs into may not be making good contact with the PC board

Don't know what the brass spring fingers are or where to find them??

The nuts on the gauges may not be making contact between the gauge studs and the PC board.
making good contact

There might be a break in the wire to the sender, especially through the bulkhead to the temp sender.

will start tracing. When I grounded the temp sender the temp gauge started moving.

Just because the vr is pulsing, does not mean it is providing enough power. It may be barely making contact (dirty, worn out) and "under load) may be failing


tried two and get the same results.
