Need some help. Tonight while driving, All the warning lights except seatbelt and srs lights all came on at once including low fuel warning light. The voltmeter also went to about 10 volts. I manage to drive the car home and bolted on a fully charged battery and it did not make any differences. Tried ABS and it still work. Could it be the alternator or something else because all the lights came on. Pleas help.

It could be the diodes in the alternator...Have the bleed A/C voltage checked. And have it load tested.

Thanks BenzMac. I drove it for a while and the alternator did make some noise. Replaced with rebuild unit and everything is back to normal. Thanks for the advice :)
