How do you know if its the diodes or the regulator if alternator isn't chargingOn A 94 Pontiac firebird?
On any alternator you can check with a voltmeter -- disconnect the positive going to the alternator, use a towel or electrical tape to isolate it, then start the car and you should read DC volts accross the terminal of 12-16v if the diodes are working, if they arent switch it to AC -- if you read > 2v your diodes are shorted I'm pretty sure the diodes and regulator are integrated into the Alternator -- so just replace that, otherwise you can take it off and they can check it at any Kragens for free.
How many diodes used alternator for Chevy?
There are 3 positive diodes and 3 negative diodes. The alternator produces AC voltage in 3 phase. Almost all car manufacturers import and domestic use 6 diodes. Diodes can be defective as either "open" or "shorted". An open diode reduces capacity of an alternator while a shorted diode causes almost no charging.
How long will an alternator last when the diodes start going bad?
It's not a good idea to to run your alternator with bad diodes. These diodes rectify the ac power generated by your alternator and turn it into dc power. You will destroy other electrical components in your car and will end up spending more money than the cost of simply replacing your alternator.
