I have an S185 with ACS Controls. Today we used it this morning with the foot controls and all worked fine, we loaded it onto the trailer and drove it about an hour away, and then when I went to unload it, the foot pedals were locked, and the hand controls light was lit up even though the switch was in the foot position. No matter which way the switch is flipped, it stays in the hand controls. Does anyone have any ideas where to begin troubleshooting on this, would it be in the switch or an actuator somewhere?? Thanks for the help.
