my alternator has no fuse, the previous owner has just wired it striaght up bypassing the fuse altogether, my battery always goes flat, how can i test it to see if it still works?
traditionally i'd test an alternator by unhooking the battery terminal while the car is running, and if the engine stays on the alternator works.
But i've heard you shouldn't do this method with an MA70 supra.
why can't I? and also what other method can i use to test the alt.?
rev the engine with the lights on? i tried that but the lights didn't change brightness, meaning the alternator is probably dead, but id like a more sure method of testing it.
