Ok my 1999 Chevy 2500 C.
Ok wen i trun on the heater. My battery
goes up to 16 plus amperage. Dont no y.
It's a brand new battery. I just installed a
brand new alternator. Brand new starter.
Pull the dash apart checked all wires did
find some that were burned fix them
gauges were fine for that. My truck olny
has 248,000 but dont think that wud
matter. If can't help I will figure it out.
Thank you all.
