I have been keeping an eye on my voltage ever since I changed my tensioner 2 weeks ago. I noticed while the trans is engaged the voltage drops to just above 12v. I increase my rpms to see if that would help. As of right now I am idling at 750rpms. As soon as I hit the gas it goes up to 13.8 and slowly climbs to mid 14s. The volts are 14.6 when I cruise and 15volts at cold start up. I do have a electric water pump and an intercooler, but that should not be enough draw. I also have a stage 1 zzp alternator booster.
What do you guys think this is pointing at? voltage regulator, alternator or is this normal? Just want to be prepared for the possible cost before I bring it to autozone for testing.
