NAS110 Oil pressure gauge not working

[El Pinchi]

Question my oil pressure gauge stopped working. How can you tell if the problem is the gauge or something else? Sender? anything else I should test for?
I researched looking for a replacement VDO and its no longer available or at least nothing identical. Any recommendations on trouble shooting and gauge part help would be appreciated.
Thanks,
Ed

Check the wiring. Does it have power and ground? If so, try disconnecting and then grounding the wire at the sender and see what happens.

Ed,
I'm not sure if the resistance units are the same but you will know if the sender is dead by testing it.

Looks like a Lucas gauge. But, you are more likely having a wiring or sender issue.

Wow, thanks Dave and Red! This is great inf. I?ll check this out this weekend.

Basically if the gauge has power and the wiring is not broken, grounding the sender wire should make the gauge go to one end and disconnecting it should make it go to the other end.
