I've been having a problem with the battery voltage on my '94 Deville. The voltage would spike above 16, then go back down for a while, then spike back up. I blew a pair of Silverstar headlamp highbeam bulbs last night, so I had to replace those! :wtf:
I figured it was the voltage regulator in the alternator going bad, so I replaced the alternator with a new one. Now I am still having the same problem! :suspect: When this happened with the original alternator, the DIC would display "Battery Voltage High". Now it will display that as well as an occasional "Battery No Charge" message. So I'm not sure if there's a loose connection causing that, but what would be causing the battery volts to be too high?
I'm not sure what to do now? I'm thinking the battery is bad??? It's only a month old though. I read in the service manual about the battery cable connection to the starter could be a cause of intermittent voltage problem. I had installed a new starter yesterday, so I'm thinking of checking to make sure the cable is tight.
Anything else I should look into? :worship:
