1.) I know I'm not the first to do this but I tried to jump start my 8n with my pickup before I knew anything about the tractor. Believe it was flooded but not relevent now. Didn't realize there was a problem until the jumper cables started to melt.
2.) bought shop manual etc. learned about 6V pos ground etc. started replacing likely electrical parts and still can't get it started. Very weak to no spark.
3.) I read every thread I could find on this and other forums, but have not been able to solve my problem.
So here is what I have and what i've done thus far. It is a newer 8N, 1952 I believe sn starts with 566, side distributor.
Starter turns motor well so solinoid and starter seem to be ok.
I have replaced the battery, ALL wiring, cleaned and reattached all grounds, replaced distributor rotor, points and condenser, coil, plugs and amp meter. Plug and coil wires are all from prior to the killing but were new before that. However, the problem appears to be before the plug wires. Have new ignition switch and starter foot switch, but have not installed them as the old ones test out good. I see no reading on the amp meter when I depress the starter switch although I don't know if that is telling me anything or not.
I have double checked the wiring to make sure the coil is wired correctly and can confirm that it is.
With ignition switch on, using a volt meter, I can see that I have 6V going to the coil. I'm getting very low voltage to the distributor.
The pole which attaches to the distributor body and then on to the points shows some voltage, less than one volt, when I go to ground. I get the same reading when I go from the coil center post to ground. I know nothing about coils ... what should I be seeing from there.
I also tried to check this voltage while depressing the starter and saw voltage jumping from 0 to ~6 although that may have been caused by me moving the test leads while trying to hold the starter down.
I tried taking the generator and voltage regulator out of the loop by removing the leads from the VR to better isolate the problem and seem to observe the same result. I now realize in my test the "B" post on the VR was still attached. I don't think that is a problem but may be relevant.
I have exceeded my knowledge of ignition systems on any engine.
Suggestions on what to check next or if the coil is bad even though new or where to start if I need to start over in my replacement, cleaning, reattachment process?
