The 1010 had been converted a negative ground and alternator. The wiring was a mess and had been patched, bypassed, rigged, and yanked out about everyway imaginable. I'm trying to get a wiring harness fabricated and have just about got my brain wrapped around what goes where and mostly why. Modifying the OEM wiring diagram from the service manual, a couple of diagrams off the internet, and a little eyeballing all have me just a little hesitant on a few things. Transposing positive ground to negative and a generator/regulator swap to the 3-wire Delco is enough to make my little brain spin.
I'm still working out a few of the details about the 3-wire alternator, indicator lights and gauges.
On the back of the ignition switch there are a pair of terminals labeled "F". What are these for our what can they do for me? I'm figuring they are ACC (Field?) spades but I thought I'd check first.
Also, was there any type of terminal block on these tractors? I have found the coil resistor and another ceramic piece next to it on the firewall. Any ideas what this piece is? Is it a terminal block? Fuse holder (to what and what kind/size fuse)? I haven't found any mention of it in the service manual.
