I switched my gauge lights to led. When I replaced the gauge cluster the oil gauge went dead. I doubt it's the sending unit for the gauge by the pressure sending unit because it was fine before pulling the cluster out. What would be the best way to test if the gauge went bad?

 

Pull the cluster and use a multimeter to test the gauge. Google is your friend, plenty of places with write-ups on how to check a gauge with a multimeter.

 

Thanks redleader289. I hook one up to see that I get.

 

Usually you can get the needle to wiggle or bounce and that tells you it’s good.

It’s probably just something simple like a loose connector. Good luck!

 

Thanks... Im going to check the wires from the sending unit to the gauge. Are both sending units by the oil filter?

 

honestly don’t know, I’m not running a factory setup.
