You're not abandoned Cpt, your post #23 & #24 were made at
12:27 AM and 04:27 AM in my timezone....sleeping time for me.
Your post #21 quoted below seemed to go off at a tangent after the black/yellow test which was far from descriptive and seemed to
indicate a problem.
I did get to a point where it said to "repair or replace" harness from motor to ignition switch. I was getting 0 ohms all the way on the black/yellow wire so at first I ignored it. Then decided to check for any continuity between all of the wires at the 6 pin connector on the motor side of that harness. It started raining, so I couldn't finish, but checking so far I got 0 ohm between R and B/W, and 15 ohm B/W and P. Meter set at 20K
You obviously measured the resistance of the black/yellow wire, the question is, was it disconnected, connected, from where to where did you measure it???
Was the key on or off, was the lanyard in position??? These things are important as reading
Zero to ground on the black/yellow wire with key on & lanyard in place will stop the spark.
You need to be very descriptive and methodical with what you're doing or keep throwing parts at it until it runs.
Jake for what it's worth I think the resistance tests a good as they can help define a magnet problem if they show the coils as good but incorrect DVA output.
Of course a user needs to know how to use a multimeter & what he's actually testing for.
