When I got the alternator I was at 13-14 voltage. They have warranty so you can always take it back and get another one. I think it has nothing to do with the afc. On the 1g that I replaced the alternator I had the afc2 and voltage was fine. Something is up with your alternator it seems like. Are your lights dimming in and out?

Or I may be wrong... could this be a sign of idle surge? Eh, still lost on whats going on. But I'm trying to help.

 

ok, when the afc is connected, the mas is connected and all making it idle lower, but when i disconect the afc it disconnects the mas which makes it idle higher, putting out enough where i can run the car without a battery. i cant read volts when i disconnect the afc, so i was just thinkin because it would run with the afc disconnected, but i wasnt think of how it idles higher. i think its the alt, but when discount tests it, they say its fine

 

we tested the alternator while the car was running and it was only putting out 12.3v or something like that.

 

also his throttle cable was a litte loose and as we moved it made a spark against the braket it mounts to, which seems a little odd to me.

 

well, we cant test how much the alternator puts out under load while its on the car if theres a draw somewhere, and yes the lights DO dim in and out, and i was gettin like 9.8 volts on the highway and then all of a sudden gettin like 12 somethin for a few seconds, then back down.

 

Change it bro mine was doing the same thing and just officially died last night on my way back home from miami. yeah it sucked ass. thats why I wasnt able to go out last night.

 

thats the thing we did change it with one i tested at pepboys and it was pulling 14 on the machine at pepboys. could it be a hot lead shorting out some where?

 

ok fixed, i put a ground strap from my firewall to the intake manifold, so YAY! its so nice to ride in somethin with more than 100 hp again.

 

you didnt ground your motor?


glad you found the problem

 

it has never been grounded or fell off and i didnt notice
