When we bought our '78 GMC Eleganza II this past August, it came with decent maintenance and repair records back to 1983. I was digging through the documentation again last night to see when the alternator was last replaced, and could not find any record of a new alternator. According to the voltmeter in the dash, the alternator is putting out about 13.5 volts under load with the lights on. Could this actually be the original alternator? (see pics below) I could not find a part number or model number on the current alternator. If it is original, does someone have a current part number and recommended brand for a replacement? I think the alternator is charging the house batteries as well as the chassis battery. Do I need to go with the 100 amp alternator, or an 80 amp?

Thanks again for the help.
Russell
