How do I check if there's power to tach and gauges. No fuse.

They were all working good one day including tach and oil lite so that leads me to believe it's not the clusterIf you have a lot of gauges acting up, likely the circuit board itself is the issue. You can take the cluster to a specialist and have them test the circuit board. Usually needs a few things resoldered and it works like new.
