Yesterday, it suddenly bounced a few times and pegged at the highest reading, staying there whether the truck was running or not.

Immediately after it happened, I smelled a sort of waxy smell, almost like something electrical over heated. Today, even though the needle never moved, the smell was stronger.

I won't be able to look at it until this weekend. In the meantime I've removed anything important I had in the truck, and made sure my insurance is up to date......... wink

Is there a fix for these tachs? Or, is there a way to bypass it? shruggy

Thanks. beer



Im not sure if the 93s are built similar tot he 97s, but on my 97 I had similar issues with gauges when it was getting up in age. Turns out that there is a connector that is snapped into the dash frame that receives a matching connector of the back of the gauge cluster. As the cluster is pushed into place the two connectors are supposed to join and make contact. After years if vibration the dash section seemed to have dropped out of the frame some. I ended up having to make two small plastic shims out of an old credit card to raise the connector up enough to make good contact again.
