I have a brand new battery and a brand new 145 amp alternator. When I start my truck the volt gauge is at 12 volts. After 10 to 15 minutes of driving it is down to 11 volts. Then a few minutes later the voltage gauge will go up to 14 volts and remain there as long as I am driving. I have to go thru this routine almost everytime I start my truck.
have the same problem?
