Hey guys,
I want to start out by saying what a great forum this is. Has helped me alot with my 1941A & 1964 140 indsutrial. I have a 1964 Farmall 140 with a 6V charging system, generator, distributor etc. wired for positive ground. The system was not charging, so I decided to get the system rebuilt. Here is what I have done so far: Generator rewound at local shop (was tagged neg ground when I picked it up) - New voltage regulator for positive ground - new battery cables for my 6V battery (hooked up positive ground) - followed all wiring per International IH570A diagram to make sure mine was correct - removed light switch & fuse holder as tractor has all lights removed and I wanted to simplify the wiring - cleaned generator & regulator mounting areas for good ground connection - after mounting & wiring everything, I polarized the system as described by John T in so many of his electrical postings on this site! - polarizing the genny should take care of the genny being marked negative ground by the rebuilder ????? - when I pull out the ignition switch, the ammeter reads approx -10 discharge - when I start the tractor, it reads approx -10 discharge - if I ground the "F" terminal on the genny, the ammeter gets burried to the positive side, and the battery reads 8V across the terminals - the battery reads 6.3V before starting and after starting without the "F" terminal grounded - I tried running a ground from the battery grounded terminal (+) to the genny and then to the VR with no change in results - suggestions ??????????????? Help !!!!!

He had over a period of months spent a fair amount of his hard earned cash on replacement parts for the old "trembler" ignition. Sadly though all his efforts seemed to be a waste of time and money as he still couldn''t get the temperamental old thing to run correctly!!
