M38A1 MRC 83 100 amp system

[battlecr]

Looking for a wiring diagram for the 100 amp system. I have a 1964 Marine Corps radio Jeep that was partially disassembled and parts missing. I have most the parts for the 100 amp system but need to hook it up to make the unit charge. Any insight would be appreciated. Most the Collins wiring is there.

Your 100 Amp system is the early version without the aircraft type Cannon connectors right? Unless you are going for restoration perfection, I would lean towards upgrading to the later version with the Cannon connectors so you get get away from the selenium rectifier which is unreliable.

My Jeep is a 1964, as I understand it mine original had the 150amp unit with the generator, rectifier and regulator in one. What I’m going back with is the 100 amp generator, the later rectifier an solid state regulator. I’m using a wiring harness from a 1952 radio Jeep. My problem is I need a diagram with labels so I can excite the generator so it will charge.

The regulator plug will have one 12 GA wire, that is excite wire, you will probably need to splice that in with the wire that goes to the ignitor.

I have complete 100A systems for sale, if you're interested.

Those connectors are by Bendix, not Cannon BTW.

Would you happen to know what the pin number is!

The connector you are holding in your hand should have some heavy gauge wires coming out of it and one 12 ga wire, that is the excite wire.

Thanks for the offer but I have all the components....I think!

Unfortunately it has 2 could one be a ground? That is my issue don’t want to fry anything!

According to DA Pamphlet 750-33, pin F goes hot +24 volts when the ignition switch is turned on.

The pin designations are molded into the black rubber, but might be hard to see without light & magnification.

Awesome, that helps a bunch. Is there a way to get a copy of that?

Lemme scan it in. The pamphlet is about repair, not installation however.

Thanks if you could scan that it would be great. I’m modifying the collins wiring to make things work. Getting close to firiping the Jeep up.

Still trying to get the generator to charge, other than that she’s mostly done. Have most of the canvas too.

Nice looking Jeep. Is it an original USMC unit?
It looks like you have had a milder winter than we have up in Washington.

PS. My hat's off to anyone who can restore a Half Track. That is hard core MV work.
