While driving the other day my instrument cluster just gave out. All the analog guages went to zero and my warning lights came on. After nursing it back home I found while driving some warning lights would go off and others just stay on. The gas, and temperature guages sometimes go wildly up then to zero.

I got a used cluster from a reputable scrap yard but with 60K more km on the system.
After removing the old unit I plugged in the one I just bought but before starting the car I turned the key to only power the dash. This was to see if the unit worked. They did and still do.., but

As I tried to start the car, it turns over once then stops. I re-installed the old unit and the car runs, I even went as far as installing the cluster I purchased, disconnecting the positive lead from the battery for about 20 minutes, and still the car will not start.

Any suggestions?

Thanks
