light
I spoke to my buddy thats wrenches on ambulances and he said he has seen a bad diode kick on a battery light, but with a meter it appears to be charging, makes sense cause the didodes make the ac to dc ,but a regular meter may read it as a dc charging voltage. His tester/ machine is sophisicated enought to detect a non dc waveform, I dont like to bother him on mondays cause he is repairing the ambulances from the w/e. I gonna take the alt to a store to test it, it maybe a diode issue. Or a computer, but the alt is new.
