Should and shouldn't don't apply, we have to work with what is and what isn't.
If I understand the situation correctly now, the DCS cart that was working fine before it took a pretty hard jolt going the the dry "dip" and now the solenoid
is clicking without the pedal being pressed and the motor
isn't running.
In a DCS drive system, those symptoms could be caused by a bad controller, or by two separate problems caused by the same physical event.
Energizing the solenoid is a two step process:
1. B+ is applied to one side of the solenoid's coil via the Reed switch, Run/Tow switch, F/R switch and the Keyswitch. We know that B+ is getting to the solenoid because it clicks.
2. The controller applies B- to the other side of the solenoid coil via Pin-7. Normally, the controller does not apply B- until the NC contacts of the pedal microswitch close (pedal pushed), but it appears to be doing so all the time. Therefore, the pedal switch is bad, OR the controller is bad, OR B- is somehow being shorted to the Blue wire between Pin-7 and the solenoid coil.
Let's fix this one before troubleshooting the not running issue.
Also, don't worry about not having a Pre-charge resistor installed for the time being. It isn't needed to troubleshoot system. Get the cart running and install one later.
