Oh noble denizens of the GMC list and fountains of all GMC knowledge,
I need the part number for the Delco 80 amp alternator on my '75
Eleganza with original 455.
I gave Darrell, Dwayne, Bubba, and Raul (at my nearby parts house) the
Delco number 1101033, since my GEN light came on pulling out of the gate
to go racing, and the alternator re-rated itself to about 40 amps. What
I got was a physically smaller alternator, with two mounting ears,
rather than the three-eared device on my motorhome. We had the GMC at
the parts house and pointed and gestured, but that just got us a
different unmountable alternator. I searched on Gene's site without success.
I can't check the part number, since one of our Corporate Information
Technology wizards loaded new software on my machines at work, and when
he left, I had no more saved mail from the GMC list on my mail server.
So could someone enlighten me:
Is the three-eared alternator a modification to my coach, did I make an
error in copying, or did the parts guys give me some other alternator?
In any event, would anyone know another Delco number that might get me
the mysterious three-eared, 80 Amp alternator so I don't have to change
the mounts on my 455? (Since this one has worked for 12 years, I intend
to overhaul it, but with our blazing speed on these things, I'd like to
have another to use while we do that and the other 40 projects in process.)
The Onan quickly sized up the situation (going racing with a wounded
alternator, spare generator that failed pre-flight, and every battery
charger we own on board) and took immediate action. It began burbling
and surging less than 20 miles down the road. I stopped and cleaned its
points. That placated it for the weekend. But, as we were loading to
return, I did the usual check on the Onan. When I pushed it back in its
hole, the roof air quit and kids boiled out of the GMC saying,
"everything quit inside". Pulled it back out - roof air came on. (Repeat
two more times, fiddling with wires.) Finally fished and pulled up on
one of the 115 AC lines to the distribution box, with Onan in hole. Roof
air came on. Kids cheered. I duct-taped the wire in that position and
drove home.
