Re: A/C compressor signal??? What does this do? (Gin)

I believe it signals the ecu when the compressor clutch is engaged to add some rpms and keep the engine from bogging. If you have a problem with charging at idle, you have a problem with your charging system and need to troubleshoot it. (if the problem is too much draw from your stereo system, that is another issue altogether and solutions are varied - do a search on that)

Re: A/C compressor signal??? What does this do? (Gin)

At 51 yrs old, my memory isn't what it used to be. However, I believe there is a higher amperage alternator which is a direct fit and could pump out enough extra voltage to help. Being that I was born and raised in Northern Iowa, and the weather not being that much different from NYC (I went to college with a bunch of guys from the Bronx, Brooklyn, a few from Queens, etc.) that would probably take care of it.
