GEN Light...

The car has an AAW Update kit installed and worked perfectly until this morning when I tried to go to work. The GEN light came on and got brighter with the RPM increasing. At idle I read 13.58; 13.48 with the fans on. Also, she tried to diesel once the ignition was killed. Any ideas?

Re: GEN Light...

What kind of update kit in wire harness?
Convert to internally reg'd alternator?
If so, internal reg going bad.

Re: GEN Light...

All new wires everywhere and she does have an internally regulated alternator that is properly hooked up. New alt is all I need? Too easy.

Re: GEN Light...

Well the internal regulator plug can be swapped out without replacing the alternator if only the regulator is bad.

Exclamation New Symptom

Went out to my car this morning and the gen light and radio were on even though the keys were out and ign off. Could this be humidity or something weird?

It's been fine for over a year and I changed/messed with nothing at all. I've put over 20K miles on the car since the wiring was redone with no issue until this. Could the internals of the alternator be bad allowing power to come back through the input wire to my ign thus powering the accessories?

Possibly a failed diode trio.

Re: GEN Light...

are you certain the ignition was really off? Not unheard of to be able to remove the key while still in the run position on a worn out ignition key cylinder.

Fair question, but yes it was. I checked twice just incase I was being a dummy.

Re: GEN Light...

put a 12v test light stick between battery cable and battery post, it should light up indicating a short somewhere. Then start unplugging fuses one at a time until the light goes out...there is your problem circuit. Then backtrack that circuit to find a pinched wire or something like that.

The Gen light and radio turn off if I pull the plug on the alt. Plug the alternated connector back in and it turns right back on.

Re: GEN Light...

What's a part number for a 10si alt that puts out 100-105 amps? I want more than stock due to the electric fans and AC.

Re: GEN Light...

The factory never made a 10si with that output. 63A was the biggest. A 94A 12si should swap straight over. Best would to rebuild what you have yourself. It's easy and you'll learn something along with saving some dough. Try and find a kit with genuine Delo-Remy parts.
