Hi all, I believe I posted this question previously but still have yet to solve and actually use my C185 because of it. The problem (s): 1)Reverse only works in fast cruise mode (cruise never has worked also) and only by putting foot to floor. It jerks hard when engages / disengages, especially with D1and D2.
Check the field diodes on Card2. My guess is they are blown. Replace with Radio Shack ones. Happy again.
2)When moving forward especially noteable in D1 and D2 the power draw is HEAVY and the front resistance coil gets hot and burned smell. I have never used the tractor since I've acquired it other than test driving short distances, and I doubt the speed has reached more than 5-7 MPH. I have tried new contractors as per Harold and has not made any difference . (I appreciate your help Harold nonetheless ; and understand it was an educated guess) Jim C suggested it may be diode issues in the varistor board...but I am currently unemployed and can't afford to keep on guessing what's wrong. Could someone please help?
