The little power resistor on the back of my stock SS 69 guage for oil pressure has a break in the (I assume) nichrome wire. Anyone know if I can get this part? Or know of a good place to send it? I really don't want to send it off as I think this is all it needs. Thanks.

Fuel and temp gages use the same resistor up through the late 70s, so I'll pick those up at the junkyard. I'm not sure if 70s cars/trucks use the same one for oil. Maybe someone knows for sure.

Thanks for the reply. I'll hit the junk yards this weekend. I measured 90 ohms on the fuel and temp resistors, does anyone know for sure if the oil pressure is the same value? By the way, this is a great site! Thanks for the help.

Yes, the 69 oil pressure gauge has a 90 ohm resistor. It's a wire wound resistor the resistors you are likely to find in a yard will be white ceramic with a color strip on one side covering the resistance material. The yellow resistor will be around 90 ohms. Yellows are not as common as red, ltblue, dkblue and orange. A good source is GM trucks. If you don't find one let me know I have some even the wire wound.

That would work but they would be a pain to fit behind the gage.

I went there first looking for resistance wire and/or a resistor, but they don't have power resistors. I don't know what the power dissipation requirements are for these guage resistors either.
