Hi, my alternator is playing up, not charging at low revs etc, I now have an uprated one to fit ( 65 amps) question is can i just fit this one without doing any damage to the car.
any advise would be great , regards Steve.
Fitting a higher rated alternator wont necessarily alter its output much at lower revs. as it will be only spinning at the same speed as the one removed . Your 18ACR would appear to be working correctly .
I had the same problem with my car, it turned out that it had been fitted with an alternator from a Ford, which had a larger pulley, meaning that it wasn't spinnng as quickly.
Now fitted, simple plug and play, car happily ticking over at 600 rpm, lights on, heater fan running, well pleased with that, but only time will tell I suppose.
Not sure of the make or model, but did a few checks this morning, when running its charging the battery at 14.5 volts, the ignition light stays off at normal idle speed, coil is nice and cool, but not happy as to how hot the alternator is getting, i know it is producing electric power etc , question is should they get hot to the touch??
