You talking about the starter motor, lights, or something else?
I've never hook up that coil back-wards but I've seen guys post that getting the polarity wrong results in a spark that is not as strong. Far as I know that's all you get.
Sounds like you have another problem, an intermittent problem, and you gotta hate intermittent problems.
The wire between the coil and distributor might have gotten up against the hot manifold and now have a bad spot on the back side that will short every chance it gets.
If your starter hangs up and won't turn you need to rework the cables and posts. That type of problem can come and go. You need large diameter cables. Short cables. Bigger around than the 12v cables in your more modern transportation. Compare and see. Get cables marked for 6v and then no longer than necessary. OEM for the 8N is 10.5" for hot and 10" for ground but you might end up with something nearer to 14" from a local auto parts. Be sure they are labeled as 6v cables and they will be big enough around for their length.
The ignition switch is not as robust as some parts so if you continue to have mystery problems get a jumper wire with clips on the end to you can get on that terminal block and jump around the switch to see if that solves the problem. Don't leave the jumper on there all night.

The starter didnt work, dont have lights. Thanks for the help. I think the voltage reg is what fried, no charging, repolarized by touching bat to arm at the regulator, saw a spark, but nothing at the ampmeter, shows slight disharge while running, like 2 amps.

Best thing to do there in reply to JM, 10-10-2004 09:29:18

is to take both the regulator and the genny in to the shop. They will test them both together.
Any alternator/genny/starter shop can do you up right. To troubleshoot electrical problems you really need to start with a full charge on the battery because low volts makes things strange.
Make sure the belt is tight. 1/2" slack with moderate pressure 1/2-way between the crank and genny pulleys. You should not be able to make the genny pulley slip using two hands on the pulley.
Quick check for low genny output is to connect a jumper between the armature and field on the genny. Start the engine and check the ammeter, remove the jumper and compare the ammeter reading. If the charging rate increased when you removed the jumper then the genny is ok so check for a regulator problem. That could be bad wiring. Corroded connections and the like. YOu really need a good ground between the genny and the regulator and there should be a forth wire off the reg to the genny that is a ground. If you don't have that wire then paint or rust on mounting brackets or mating surfaces can cause problems, intermitant problems even.
You might need to rework the wiring cleaning and remaking all the terminations. Repair or replace any damaged, worn or corroded wires. A fresh, $15 wiring harness is maybe the best $15 you will ever spend on that tractor. Close second and third are the $15 copper-core plug wires and the $15 for battery cables. Farm/ranch stores should have all of it. Make sure you get the 'after SN ****' (side-mount) harness.
