Speedo Not Working Question

[bigboi]

So... My OEM speedo was working just fine, but then I was farting around in the engine bay and I swapped the wires going to the coil (Positive and Negative). Don't ask why I did this, I just 'thought' they were backwards. Anyhow, the speedo stopped working. I swapped the wires back to the original spot they were in and the speedo still doesn't work.

Now it could have been a coincidence the speedo went out when I swapped the coil wires, then again it could have nothing to do with it.

I removed the dash gauge cluster and checked to make sure the speedo cable was in securely, I unscrewed it, screwed it back it, still doesn't work.



I am having some lighting issues on the printed circuit board so I bought a new one and am currently waiting for it to arrive. That could be the problem.

Do you think I might have fried my speedo by swapping the coil wires? That couldn't have anything to do with it - could it?

OEM speedometer is mechanical, not electrical. Changing the wires wouldn't have done anything to it.

You could disconnect the cable from one end and either spin the free cable (if you disconnected from the tranny) watching the speedometer, or take a drive and just watch the cable end for movement if you disconnected the gauge end.
