I was doing an LED swap on my center gauges. I changed out the gauge face And had to pull the needles. Well i assumed that since the car was off when i removed the cluster the gauges needles could be reinstalled on 0. I guess I was wrong.

How can I find the correct reading for these gauges so i can install the needles correctly?

 

wow, that'll be tough for the oil psi. my best bet would be to get a mechanical oil psi guage, hook it up to your car and adjust the needle so that the values match. As far as the voltage, that should be easy. Just get a multi-meter, and turn the car on to get the operational voltage... usually about 14 volts, and then put the needle on to match that voltage. sounds like you got yourself into a pickle.

 

Would my oil psi not be the same at idel as everyone else

 

Every motor is different depending on type of oil ect ect

 

You're supposed to pull the needle stopper and mark where the needle lays. Reinstall according to the mark. Should've asked before you did anything.

 

Really? Thats for the info..... Anyway like I stated previously I figured since the car was reading zero with the car off i could just replace the needles back to zero
