Hello, I’m Matthew. I have a 1993 Nissan Stanza ALTIMA GXE with power windows, power door locks, cd/ cass radio, everything but a sun roof. I have replaced the alternator several times. In a month’s time, the alternator has gone bad and won’t charge the battery. The volts drop to 12.5 to 13.00 volts at idle, and my car’s brake and battery light comes on, I have a new alternator. My voltage is 13.64 volts at idle. My repair manual states voltage should be between 14 to 15 volts but not to exceed the listed volts, and if it’s lower or higher, there is problem within the alternator,
The question is the alternators I buy from the auto store are 80AMP alt’s, but I have seen in Texas that they sell 100 AMP for the same car. Are my AMPS too low for that car?
I live in Florida in Crescent City FL 32112.
How do I test for AMPs on an alternator?
