the drawbacks to having a voltmeter
I'm driving the wifes 2018 premium II the other day and see the voltmeter fluctuating.. sometimes its just over 14 and then it drops off to about 13 (the scale on the meter doesn't compute when you look at it).. when I get home I put my meter on it and it reads 12.7 volts.. hmmmm must be a problem.. take it to the dealership and the service mgr says the new cars don't operate like we're used to.. no 14 volts all the time.. he asked if I'd had any battery issues with slow crank or anything.. nope, none of the that... according to him they're trying to reduce the amount of power loss from the engine to turn the alternator.. apparently in some situations on the bigger vehicles it can take 5 hp from the engine to turn the alternator so they've devised ways to reduce the drag from the alternator..
anyone else watched the dancing voltmeter?
guess I'll find out soon enough if he's right or not..
