the car is getting crappy voltage when the afc is connected, but then when i disconnect it, the car can run with the battery disconnected. whats wrong? is it something with the mas?

 

what??? your car should always run with the battery disconnected. unless your afc is making your car idle extremely low and the alternator isnt charging at that low of rpm. Sounds like a weird problem.

You know who to call..... GHOSTBUSTERS!!!

 

actually i wanted some real help. lol. im gonna try and figure it out, i hate having to figure stuff out by myself no body knows anything in my area

 

ok, its something with the MAS! i disconnect the MAS and the car can run with the terminal disconnected. any ideas?

 

ok i dont think its anything to do with the mas or afc. i think its just cause it idles higher when i disconnect those. ok so dont worry about the afc or MAS. what else would it be...its NOT the alternator. its been tested and puts out the right amount. not the wiring, i hooked up a volt meter and it was getting power all thru the wires

 

screw the autozone alternators, i dont think the guy ever put the thing under the right load. im just gonna get one i know is good and see if that works

 

Discount Auto or eh Advance Auto Parts is your friend lol. I got my alternator from them when I had my 1g. So I'm guessing you narrow it down to being the alternator?

 

I find your first post confusing. Let's try to clear it up.

The voltage coming from the alternator is low when the AFC is hooked up. What voltage does it put out?

The voltage goes back to normal, around 14 volts, when the AFC is disconnected.

Ok, what are the settings on your AFC? The only connections I can see are wiring problems with the AFC shorting something or a similar problem, or the correction on the AFC making the car die out and idle too low.

What is it idling at when the voltage is too low? Have you set your idle properly recently?

 

i actually got it from advance...but they test it and are like yea its fine blah blah, but my friend said that they said that for his but they sucked, like when its cold it gets good volts like 13 but then after a little it goes down to like 11.5, then it spikes up for a couple seconds. i checked the wiring to the battery, and i dont know what else it could be

 

well, i dont think it has anything to do with the afc, i think it was only because it raised the idle when i disconnected it, and it idles around 1k normally.
