Dead alt cause radio not to work?

chowda633 · Oct 5, 2007

Wondering if my alt is dead or dying. Car still will not run right. But now DSMLink will not connect. The radio stopped working. And I tryed to drive it around the block running pig rich to see what would happen and the head lights are stuck on.

Wondering if a dead alt will cause the radio not to work and it not be able to connect to dsm link. I have a otptima yellow top in the car so its got plenty of juice.

Thanks,
Josh

Alt is def. dead.

I'm just curious even though your alt. might be dead/dying. I don't believe that would cause your headlights to be stuck on.

I know that if the alt. is dying or dead your electronics turn off they don't spring to life and stay on.

I would check out the ECU as well. Since DSMLINK will not connect and you say your battery has enough juice.

+1 for checking your ECU. Does the ECU have an unpleasant smell to it?

+2.

For a dying alternator, his gauge lighting(I.E. battery light) should stay on. I would first look at the ECU as it was said, then I would look at the fuse box under the hood(just in case you haven't done so already). Also, check the wiring. I had an issue similar to this a few years back.

Careful, I just had this problem and it was the voltage regulator in the alternator. MMCD was reading 17-18 volts from the battery. Some radios will not work above a certain input voltage. Replaced the alternator and everything was OK.

Thanks guys autozoned my alts. 4 out of the 5 are dead LOL

. Also the alt fuse blew so I tryed to jump it with some wire and said. "Whats the worst that can happen?" Start the car up and FOOM!!! Up in flames! Hope everything is ok LOL

. Going to get a real fuse in a minute! Supposedly dsmlink will not connect with a dead alt.
