I'm going to go through my wiring, but one point is I did not have any issues until I added the A/C and the only real difference is the compressor electrical load as the high speed blower was used for heat (although rarely).
I read through the MAD stuff and will go ahead and relocate the sensing wire to the junction which is at the rear of the motor area, but the sensing lead has been connected the way it is for several years with no issues.
And last but not least do the testing Clay recommended to come up with a "power demand" number as I agree it's best to know what is required. Got my work cut out for me over the next few days...
