Plugging problem

Very stiff plugging when traveling power unit 1st direction and then plug. No problem when traveling forks first direction and then plug. The problem is not: Sevcon controller, dist. panel, F/W contactor, fwd/rev contactor or travel pot. Any suggestions besides an old priest, a young priest and some holy water???

Make sure your cables are connected correctly on the 1A contactor and the foward reverse contactor.. then green ground wire also should be on the the top lug of the 1A contactor.. if those are ok try a diffrent Sevcon.. good luck

Check your key end keyway on your motor shaft. (both of them)

there really should not be anyway that a power cable has anything to do with directional related changes, as the power goes through the same cables in both directions.

Yes...even swapped drive motors just to make sure. I'm reasonably sure its a power cable issue. They of course check ok, but that doesn't mean anything under a load. I really hate to just throw parts at it like this but unfortunately that's where I'm at now.

are all the poles on the drive motors good and tight, and no shorts to frame after trying to drive then plug, in the power unit first direction?
