I have a 1981 C30 van.The oil prs and temp guages don't work.The fuse is good and the senders are hooked up.There looks to be a new temp sender also.
So far I tries disconnecting the oil sender wire and grounding it but the guage didn't move.I also tried putting a test light between the sender wire and ground(sender unplugged) and no test light.The key was on during this.
Any help would be great.
Thanks

I could try it,but it seems odd that both the temp and oil would both be dead.
Should the guages move when there sender wire is grounded out???I now the gas guage worked this way when I grounded out the wire.
The gas and voltage guages work just not the temp and oil.
