Have you checked all the grounds for the guages? When a few of ours stopped working last summer I found the problem to be loose wire connections at the grounding block under the dash.

waimo,

Starting with the ground block is definetly the first thing you want to check. You could run an auxillary jumper wire from this block (which may be in the area underneath your throttle controls) to a know good ground. (this being the battery negative terminal to be sure)

Besides that, the MDC control unit the drives the guages is know to be problematic and fail at times.

Once again I would pull the wiring loom connectors in and out a few times to make sure they are getting their proper connection.

I agree with Pistol Pete!

Run a good ground wire from the battery negative terminal to the dash ground.

The battery selector switch has nothing to do with the problem. Its function is to select the source of the +12V supply. If your engine started then it is doing its job.

You might have problems with your key switch if running the ground wire does not clear things up. The key switch supplies 12 volts to the dash when it is in the on position.
