They made v belt versions For some of the MD trucks. Mine was for a tall deck 429. You can also swap your 1 g pulley if you use a shim approximately the thickness of the cooling fan from the 1g. Discard the fan obviously.So on my 90’ F350 with v belts, can I change the serpentine pully out to a v belt pully to put a 3 G on it?
Oooff... yeah follow the pigtail wires and the single stator wire and look for continuity. Also, does it have a megafuse between the output to the battery? It should, if so its worth it to check that if it literally is not producing a charge at all. Check the connections on the megafuse block as well.Well, took the alt back to the store. Three runs on their test jig = 15 volts each time. Yep, quite possible that the "core" I turned in was just fine.
So, back to the wiring. <hangs head>
Young fella at the store said he'd seen this before when a battery was weak. Said it was the fusible link on the yellow/white sensor wire. But, but... thought I had continuity on that wire!
Back to the multimeter.....

Ah yeppp, thats what I was thinking. Glad you found it!Eureka! Yes, the continuity on the w/y sensor wire is good, but.... continuity of the 12v output from the alt to the solenoid is a no-go.
Gotta be the fusible in the alternator cable. Guessing I'll need to undo the loom to find the link? Which end would be the likely location of it?
Still, over 11 years of owning this beast, I'm still learning. Think I'll re-wire and upgrade to a 175 mega sometime soon.
Also, what batteries are you running in your rig and whats their CA ratings?
Is that OE sizing? Never heard of different sizes under the hood, even in vans. On the contrary I've always heard *not* to mix batteries of different sizes, since one will generally poop out first and take the other one with it. Or at the very least leave you with a problem.Realized I forgot to answer this question.... driver's side has the usual group 65 (I went for an 850CCA)
Passenger side has very little room, due to the heat flap-box. That side gets an uncommon group 50, which is very narrow. Only 600 CCA. Fortunately, my part of the world only gets around freezing may be two weeks out of the year, and the block heater works great.

Walked into a local battery shop years ago, carrying an old 50, and the guy said : "van or boat?"
Did you ever get your alternator charging?

It sure is. I'm sure that it's longer, but it looks as narrow as the one that was in my 1975 Mustang II with a 302 in it.Geezzz thats a narrow battery!
Um, er, well... Only because you asked.....
Somewhere in the process I actually DISCONNECTED the alternator output wire from the solenoid. Thought I was disconnecting the glowplug power wires, but, of course, THOSE would be the yellow wires!
Put the new 50 on a charger, and that's as far as I got. Tomorrow, we shall see.
