I am having an intermittent problem with not getting current to the solenoid. After letting the cart sit for a few days, I couldnt get the solenoid to click again. No 36v to the "actuator" terminal of the solenoid. I tapped the "pot box" and microswitch and it started working again. My question is are there any parts in the pot box that tapping would effect or does this sound like my microswitch going bad?
