Rally dash oil pressure gauge issue.

Geez!
That will burn up the gage.

Use a 10 ohm resistor or variable resistor next time for testing any of these gages.
Or do what I did. I had a bunch of 22 ohm resistors. Use one alone the gage should go the middle mark. Use two twisted together in parallel and that's 11 ohms.
Put two in series and that's 44 ohms.

That may be it. The gauge burned up. If I open it is itvrepairable? There seems to be no one making reproduction ones I haven't checked e bay yet.
