I'm restoring an Allis Chalmers C that had been
retrofited to a 12 volt system. The restoration
includes putting it back to a 6 volt
configuration. It appears the ground cable to the
frame must go to the negative pole of the battery
and the positive to the starter terminal however I
can't find any confirmation of that in the books I
have. Any comment? Thanks.

We make original type cloth covered wiring harnesses for farm tractors. The AC model B,C,CA harness set is priced at $99 + $6 USA shipping. This includes wiring to the lamp housings, and other individual leads. We also have the 3 position light switch, mechanical cutout relay, cloth covered battery cables, spark plug wires, ignition switches, fuse holders, starter relays and other switches. All of our harnesses are labled, and include a connection sheet. See our web site for a listing of prices and applications.

The 6 volt system has a positive ground.
Take a look at the drawing enclosed.

Dick, that schematic for the C is super! Would you happen to have a similar drawing for a 61 Gas D17. Serial# 33383. I plan to do a little clean up and that will help me keep everything straight after I get the sweetheart shiney. Thanks in advance.

The first one is for the early D 17 and if you click on NEXT you will find one fer the later D 17

These are not as crisp as the CA diagram from above. If you have some photo software you can blow it up and print it a little larger.

No real difference between the B, C, and CA diagrams except for the pull starter rod in the picture.

Dick, Thanks for the wiring diagram! I don't have the photo software but the printer did a good enough job that I can make everything out. I appreciate the help!

I assume if you are going back to 6 volt, you have an original generator that is positive ground you will be using a cutout relay and resistor light switch??
