Power problem...please take a look!

Quick question:

Does anyone know why when I am idling and use my power windows, sunroof, or my system bumps real hard....my rpms will drop and it seems as though it may stall, (hasnt yet though)...they drop a few hundred.

THanks anyone.

Maybe your alt is about to go? I don't know though. I think that you should check it out, also for your system get a cap. This way your lights wont dim when you bumb (assuming they do if you are bumping that hard)

Well for one, check your rpm gauge without no electrical **** on, and see if the cars idle speed is correct, if not then go to a part store and get like a lil tester, to check if its your battery or your alternator. If you have a lot of watts on your system, then most likely like he said u would need a cap with 1 farat, and maybe a powerfull batteery with more ampage. Hopefully you wouldn't need an alternator, if you do then check out ww.nopionline.com. I got a good battery, from NAPA, for about $60, with like 800 amps and it does the job. Thank god i don't need an alternator.

well, if your lights arnt dimming when that happens, then it has to be the alternator, as the battary will keep the lights going fine, but the added load on the alternator will cause a force against it's movement (as the pull increases the magnetic field strength inside the alternator coil and makes it harder to turn) if the coil is shorting and your only running like on coil instead of all of them this could cause the problem (i dont know how the alternator for the mx6 is exactly set up) you might also have some sort of short in the switch wiring, etc... which may cause more load on the system then the normal usage of the windows, etc... so i say check the battary, then the alternator, then look for shorts...

Check the ground to the system. See if it gets hot when you are bumping it. Also make sure that the connection where the ground is, is a clean metal surface, if its not then sand it to make a good connection. Had the same problem with my first system a while ago.
