Mike,
It's TM 9-834 VEHICULAR GENERAL PURPOSE UNIT EQUIPMENT. Here is a link to one you can find online, no download required.
https://www.ibiblio.org/hyperwar/USA...fs/TM9-834.pdf
The pages you want are Pages 38-49.
So is yours up and running? According to the Hobart Brothers website they made over a 100,000 of these during WW2. Looking around the internet I found one with a serial number about 1500 under mine that was reportedly built July 1945. So I think mine might be right in that end of the war time frame.
Do you have pictures of yours?
Matt
