Voltmeter jumps backwards.

[CB2L]

When I turn the key on, the voltmeter goes backwards. What would cause this? Could it have anything to do with the fact that I've got a crank/no start situation going on?

Headlights/taillights/blinkers all work.

It would have something to do with the polarity of the gauge being backwards.

Did you just hook it? It sounds like the wires are on backwards.

Or a bad gauge. Check it with another voltmeter that you know is good.

yeah, it's new - all of the gauges are. i was wondering if just switching the wires might do it; i'll give that a shot. it's a Painless harness, and there was a mistake on the labeling of the oil gauge/speedo wires, so...maybe here too. though it did match the directions.
