Monitors not ready.

[yajstylez]

Monitors not ready, checked the battery for proper volt during idle; around 14.7 volts. Engine does have a p1500 code. Alternator was checked fine at Autozone. Battery was checked fine at Wal-mart (I had to charge it).

Now while I had let it idle longer, the battery light and brake light came on, so I went ahead to go check the volts at the battery again and it gave me under 12 volts; roughly 11.5-11.7 volts only. I rev'ed up the car and the volts went back up to 14.7 and stood there after I let off leaving idling. Now even while driving, sometimes the brake light and battery light would stay on intermittently; suggesting volts would be under 12v during the lights on.

With the p1500 code, and the stuff I've already checked, would you still blame the alternator? Or can a bad FR wire from the alternator cause the voltages to drop? I will re-wire it soon, but like to know opinions/advices. Thanks.

Bad Alternator......
Mitsubishi Alternator's are not good, most of other brand alternator they just stop working, But Mitsubishi Alternator some times they work and some times doesn't,
But once they have a fault, that's it, my alternator does not charge at idle, it will after 3000 RPM, But I just giving some time to get worst to change it, ( I just don't want to argue with the guy at the Auto Parts).
It is your bad Alternator.

Alternator. Auto stores do a worthless test of them. Only a starter/alternator repair shop does a good and all inclusive test. Or you can do a halfway decent test here: http://www.dsmtuners.com/forums/new...reeway-electrical-problems.html#post151165661
