key on not running draw

Also from what I've read here it appears you checked field draw using the factory blue for a power source. That is NOT what I suggested, and I thought I explained why. You want to measure that with one field jumpered direct to battery. This eliminates any drop/ problems in the factory wiring, and if the field has a partial short, will help to show it up

If the factory wiring has a voltage drop problem, and many? most? do, then using ANY of the factory wiring to check field draw can help hide a problem

Then, after you determine the field is OK, you can if you wish, hook it all up and see what the drop looks like through the factory harness.

The only way to tell if you have a harness drop problem, vs some component drawing too much current, is to isolate everthing on the circuit, and check the draw of each device one by one. You have to use your head as to 'what' as say, the choke if used, I'm not sure there IS a spec for that or for the ignition system.
