Wiring questions

[snowdad]

Good morning to everyone. I have a couple of questions on the wiring harness. Is the entire harness 16 ga and if not which circuits are different and what guage are they? Excluding the battery cables.

Secondly, where can one find individual Douglas components? My restoration (that I hope to get back on soon) is a 1953 M-37/M-42 and has the Douglas system. I have plenty of shells and hope to be able to salvage most of the bushings. I need the terminals and the rubber grommets. Where can one purchase these individually? Thanks in advance

Hi Phillip,

I would contact John Bizal @ Midwest Military or VPW they both have them.

I would ask John B about the wire gauge question while you are ordering the parts you need, he is a wealth of information.

I don't think John sells individual components, just the set of pieces. Vintage Wiring of Maine does though.

Most of the harness is 14g wire with a few circuits of 8g & 12g. I don't recall running into any 16g yet or seeing it used in the parts manual.

Thanks Mike. I got a little confused there. I thought it was mostly 16 ga. Can you tell me which circuits are 8 and 12 ga?

Yes, give me a day or two to take a look at the parts manual. If you have the '54 edition of the ORD 9 manual, that is where I am getting my info from.

Thanks. I have several of the manuals but not sure the date and have never come across the wiring sizes.

Phillip,

The ORD 9 TM shows 8g wire is used in the harness running between the generator & regulator (the sheathed cable, PN 7351057), in the regulator harness (coming off the other side of the regulator, PN CC-150140) circuit #4 to the starter; and the radio power harness (PN 7731417) circuits #48 & 73.

It also shows 12g wire used in the harness running between the generator & regulator (PN 7351057) and in the regulator harness (PN CC-150140) circuit #10 to the circuit breakers.

Everything else I see in the TM shows 14g wire for the M37.

I don't know what the individual circuit numbers are for the wires in the generator-regulator cable. Maybe someone who has taken it apart may know.

Hope this helps.

Hello Snowdad, I picked up a lot if not all of my shells ,grommets, etc. from a fellow at a swap meet in Pa. I'll have to do a little digging to locate the name. I do believe he'll be at the swap meet in Jim Throp Pa. Again I'll have to look for the date on that. I picked up extras of each, even the double shell type. What do you need and how many?

Hello Snowdad. I did a little digging and found where I got the Douglas parts, Try Brian Asbury I think he's with Red ball, I have a phone no. But not sure if it's good 519-853-1738 hope this helps. Ed
