Car won't start after a few days after fully charging the battery. Instrument panel lights dim when window button is pressed. The brake, abs, air bag light are on when the battery is very low. It won't start again when those lights are on. Car almost dies when i turn on the a/c. This is when brake, abs, air bag light are on. chirp sound is heard after a cold start. Could be the alternator bearings or belt. The battery light has never come on. Only comes on when in the "ON" position. Battery terminal cables have the rust colour (reddish/brown). Battery was tested and passed.
The battery voltage with the car off is around 12.xx and with the car running 14.xx. This was 2 weeks ago. Unfortunately my multimeter has been acting funny. The voltage keeps increasing when I test the battery (jumps from 12.xx, 14.xx, 15.xx, 16.xx). It doesn't stay at a constant number. Same with the car running.
