EA charging rate problems
Ive been having some Alternator issues recently. The car had a 70amp Alternator that was tested by a AutoElec and the alternator was fine. The problem was that when you have your headlights on, brake, and indicators, the charging rate goes from just above 14v to 11v??!! also if you have the stereo on, the charging rate goes from just above 14 down to 12v. I assumed it was something todo with the Amps and Stereo so i dissconnected them. It was still dropping from above 14v to 13v when you have the indicator on and brake but no headlights.
So i got my hands on a 85amp Alternator in good nic, fitted that, and it still drops the same, but now when the headlights are on if you use the indicator or brakes, it drops to 11v!!!
Im stumped! Whats going on? Ive considered going to a auto elec but they seem to charge $70 and all i get told is what i think it is (its happened recently with the dizzy).
