All the gauges go too zero sometimes the dashboard lights stays on. Sometimes gauges go too zero and when turned off it won't crank until it sits for a while if the lights are not on in dashboard.

More than likely this is a connection issue so we need to check and make sure the cluster still has power when it goes out. If it does then we need to wiggle the connector on the cluster and find out if the gauges come back on and off. If so then we need to replace the connector on the back of the cluster.

Here is a guide that will help with testing the voltage:

Below is the wiring diagrams that we need in order to test these as well.

Let me know if you have questions on this. Thanks
