Don"t shoot! I hang out on the Farmall board. A friend asked me to look at a Case D for him that he"s thinking of buying. It still has the 6 volt system. I just wanted to check: that should be hooked up with positive ground, right? It is currently hooked negative ground. It has a mag, but the generator might get confused.
Also, this outfit has a big, heavy industrial loader on it, so it"s hard to see in there. Where is the timing mark? Is it on the front pulley, or is there an inspection hole near the flywheel? Should it be set so the impulse trips at TDC?
Thanks for the help!
Paul

DC series were all negative ground !!

Timing mark is on flywheel under a little inspection port just under starter motor. Your plan for timing the mag is correct

6 volt negative, eh? Wierd. I"ll make sure it stays negative ground then.
All the 6 volt stuff that I"ve run into has been positive ground, including old cars, trucks, and tractors, of many different brands. I have heard that there are some 6 V neg systems out there. I wonder what made them do that?
Thanks for the help!
Paul
