Thanks for using JA . What kind of problems are you having?

Customer: replied 2 years ago.
Voltage meter pegging to 18 every few minutes then going back to normal. Fuel gauge not reading, but fluctuates every so often. Codes say voltage low and high on fuel level meter. Changed fuel pump, battery temp gauge and put new battery terminals on and checked for any other bad connections. Nothing has changed

Have you checked it with a meter at the battery to see if the voltage is really spiking?

Customer: replied 2 years ago.
Its not.
Expert:  moparfl replied 2 years ago.

This sounds like you have a bad instrument cluster.

It was supposedly checked also when in the shop getting the fuel pump put in. Said it was ok
Expert:  moparfl replied 2 years ago.

If the voltage is not spiking at the battery as you stated then the circuit board in the cluster has to be bad. The dealer has not way to check this it would have to be removed and sent in for repair.
