dual belted alternator???
Anyone have any info on why an alternator would have been dual belted on a 72 blazer? the belt is just like the regular one, goes around the fan/waterpump, crank, and alternator, the pulley on the alternator looks factory, I thought it might have had something to do with some option like heavy duty radiator or cooling system, or high amp alternator. any info would be great. thanks
