    What the little resistor thing on the back of the oil pressure (OEM electric) gauge is called, and if they sell it seperately? I dropped my gauge this morning and broke the thing - I picked one up at the boneyard, but now my gauge is pegged at 60 psi (at idle), and I have no choke function [​IMG] The boneyard one has a yellow stripe on it, and the OEM was orange - is there a difference?

    If it is a resistor then those colored bands tell the value of the resistor. There should be three colored bands (for a normal resistor). If you give those to me I'll tell you the value.

    it's only got one 1/4" stripe across it - no numbers or anything. I don't really know what it is - I just assumed it's a resistor, since it's ceramic.

    I've seen numerous of these as well. Best bet is to collect as many as you can, and keep swapping until your gauge reads what you think is correct, or what it was reading before. I believe the "resistors" must have been used to "tune" the gauges, or else there wouldn't have been any difference in them.

    Thanks - I'll start harassing the other boneyards in the morning!

    One Stripe would indicate a Capacitor. should be a number on it for it's value. One stripe on one end could also be a Diode.

    It's not my damn planet monkey boy!

    These are definitely not diodes or capacitors, at least in the respect that I think of them. (no electrician here!)

    They are perfectly flat ceramic pieces, with colored "tape" stuck to the back of them. Not really a stripe, just some different colored tape. They are maybe 1/8" thick, about 1" long. Appear to be totally ceramic, except metal around the two post holes where it is held to the gauge.

    Anyone want to test resistance on a couple of them they have lying around?

    I found the answer to my prayers this morning - an entirely different gauge assembly for $10. Works perfect, and reads within a few psi of the mechanical. Those little ceramic things must be tuned to each individual gauge.

    Take the broken gauge to Radio Shack and see if they can test it or fix it for you.

    Got a multimeter, and could you test resistance of the different ceramic pieces inthe name of science? : )

    The yellow one read 3.72 ohms, and another lavender/purple one read 4.14 ohms.
