Do I need A new ALT?

[mackey]

Well at the dragstrip my battery light decided to come on and stay on for good. I don't really know what happened but the battery is no longer charging. I checked almost all of the grounds and wires. If i need a new alt which do you people recommend?

Take it to autozone and get tested to see if its bad. I'm not sure if theres a way to hook a voltage meter up to it to check that way. I dont think it costs anything, but you can always call to make sure. Hell... it might just be your battery is gone and need a new one.

Stupid question... but have you checked all of your connections?

I replaced mine with the autozone one it has a life time warrenty. If it takes a dump just replace it again. If you want to spend the big buck the 3g makes some high amp alts.

I just want my stang to run... How much was the autozone lifetime?

If you hook up a volt meter to your batt. it should read at least 12.4 or around there and with a little throttle to it it should read at least 14.00 anything less than 14.something usually means your alt is not charging properly.

I think it was $110 with a $40 core charge.

You can get a pa-performance 130 amp alternator for 189.00 from 50resto.

is your car's voltage/charging meter good? i notice that when i was changing my u/d pullies that it had a warning that some ford alternators have a longer shaft so if u put new pullies on without a lock washer you might have charging problems... or it could be a bad diode or connection somewhere

 

[mackey]

I have stock pullies. My dad said i probably burnt up one of the diodes. No way i can replace that right? It is inside the alternator. The light came on when the rpms were around 6000.

Diodes are in the alt you're going to have to replace it( the alt. that is).
