Hey everyone,

I've been having issues with my 88 foxbody. I replaced my IAC and alternator. Yet, when I have my a/c on while driving for a while or my headlights on while driving for a while my battery gauge decreases and it starts to sputter. If driven long enough it will want to shut off, the only way to keep it going is to have my foot on the gas and brake. Any recommendations?

Any aftermarket parts?
Stock alternator?

Sounds like a voltage issue.

What's the state of your charging system? Stock alt? what pullies?

Can you take a voltage reading at idle with nothing on, and then one with everything on? Ideally you want 13.4-14.6 volts at idle to maintain a positive charge.
