Guest Posted May 10, 2012 Report Share Posted May 10, 2012 you mean with age? or while the car is on with heat? if its with heat while the car is on, then thats normal. i'll charge at like 14.8 cold then when warm it'll drop to 14.2.

Rich65 Posted May 10, 2012 Report Share Posted May 10, 2012 I always used to just start the car pull the positive cable off the battery and if it runs the alt is good, if it dies the alt is bad. Its ghetto I know. Quote Link to comment Share on other sites More sharing options...
