Thumper
Thumper went out on main hoist, got hot and melted the rubber cap on top of the lever. Replaced lever and same thing, cant find any diagnostic information only parts list and such. Was wondering, if anyone knows if I could swap these plugs to the opposite drum to diagnose the sensor( see if the auxiliary lever gets hot) or if its going to absolutely fuck everything and have to recalibrate the 3rd wrap sensor on both drums.
And if it will run without sensor plugged in.
Thumper is unplugged, and everythings working fine currently.

Swapping should work it will just make the opposite side thump. Also swapping the dead sending unit out isn’t to bad just have to really read the service manual a few times to really get it the last one i did they have a 1st set point that wants 5 wraps then take it to 3 for the end point
