M-135 electrical

[Stan Leschert]

Could someone tell me which TM covers the 24v charging system on an 1956 M-135, and is it posted here? We went from a positive charge on the Amp meter to a slow discharge. I know that one of the batteries is suspect, ( and I do have 2 spares), but I would like to know more about the Voltage Reg, and the curcuit which deals with the generator. My partner, who actually owns the Big "M", is a mechanic, but we won't have time until after New Years' to try and dig into it. I appreciate your help. I'd love to take it up to the Legion for New Year's Eve and brag about how the Toy Drive went........Astounding! I'll post a full set of pictures later. Thanks.

Stan, The TM 9-8024 covers the charging system in detail. It has system tests and pictures showing where to connect test equipment. It also has wiring diagrams.

If you can open up the regulator, and clean the relay contacts, you may be able to fix the problem.

Just put a bid in. A hard copy is way more usefull on the work bench. I can't down load that TM from the resource section of this site. Gotta get the truck fixed. The New Years' thing won't happen unless I put a 3 KW genset and a 30 Amp charger in the box and leave it running!

Mind you, after a day of trickle charging, The Big "M" fired on the first crank! Now if I can just get that last screw of the Reg cover.....

Thanks, you guys have been so good and knowledgable. Helpfull too!

Bought the TM, beat up the V Reg, and guess what, the over voltage relay now is certified for a Welder's "C" ticket. Off to the shop for a rebuild!
