What else can I help you with?
If alternator diodes fried do you change entire alternator?
I'n most cases replacement is your only option but if you can find an alternator repair shop the Rectifier (diode) assembly can be replaced, if it has damaged the stator (copper windings) is not likely practical to repair..
Where are the alternator diodes on a 1994 Ford Taurus?
Unless things have changed, the diodes are part of the alternator. The voltage regulator is attached to the alternator but the diodes are part of the alternator.
Does a 1978 Ford pickup have diodes?
The alternator in any Ford has diodes. Is that what you are asking about?
Will a bad battery ruin a new alternator?
Yes, it can. A completely dead battery can blow the alternator diodes, at least in older systems - I am not so certain about newer systems, whether or not they are protected against this annoyance. In any case, the alternator is not generally designed to charge a battery from scratch, but just to keep it charged during normal use. The alternator will not be completely ruined, but it will not function until the diodes are replaced.
Can a crankshaft sensor on a 96 SL1 go bad after the alternator has been replaced?
You more than likely have a bad connection or damaged the CPS when removing the alternator
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.
How do you find out what systems are damaged after connecting the battery in reverse on a 1989 Ford F-150?
You can count on the alternator diodes being fried. But you might be able to have it tested. After that, much of the OTHER stuff has protection. Unfortunately, polarity protection is difficult if not impossible with an alternator.
What is the purpose of a diode in an alternator?
The diodes are part of the rectifier assembly that converts the alternator's AC output to DC. The alternator's charging output flows through six diodes in the rectifier assembly before it goes to the battery and electrical system.
What would go bad if you wired an alternator reverse polarity?
You would probably toast the diodes in the alternator.
What happens when the battery is reversed and you run it like that a little bit Then the altanater goes out on you and none of the lights work except the charge light and the replaced headlights?
I'm thinking that anything that is polarity sensitive might have been damaged, including the engine control unit. The voltage regulator and alternator diodes may have been blown.
Why do headlights on your escort van flicker?
Have the alternator tested. I would suspect one or more of the diodes in the alternator are bad.
