Any zero off experts on here? We went out skiing today, noticed the zero off would not apply throttle when in jump mode. Switch seems to be working because it shows the $ on the gauge when the rope is loaded. Yes the jump letter is high enough it's actually set at T. The throttle is getting pushed all the way to the stop after engaged. It was working fine yesterday, can't figure it out. Went through the owners manual didn't really help. Any suggestions? Thanks!
