04 club car iq wont go no solonoied click nothing ... i have 50.5 volts across the pack pulled the plug on the mcor and jumped it . still 0 response is it the O.B.C. or controller i have no battery light not sure on how to pull codes either. a lttle guidence please

To begin troubleshooting check the voltage at key points in the system. The absence of a solenoid click usually indicates that the controller isn't providing the necessary ground for the solenoid to engage. However, before the controller can allow this, it needs to receive several signals and meet specific conditions.
Start by making sure that the solenoid is receiving the correct voltage. You should verify that the pack voltage, which in your case is 50.5 volts, is present on the large RED cable connected to the solenoid. Without the correct voltage reaching the solenoid, it won’t engage, no matter how well the controller is functioning. After this, check to see if voltage is making its way through the resistor to the B+ terminal on the controller. The resistor itself shouldn’t be hot, but voltage should be present at the B+ terminal, indicating that power is reaching the controller. If there’s no voltage at the B+ terminal, this suggests an issue with either the resistor or the wiring leading to the controller.
The next step is to test the small posts on the solenoid, which control its activation. To do this, make sure that the Tow/Run switch is set to RUN, and the Key switch is turned ON. Under these conditions, the small posts on the solenoid should be receiving pack voltage. If they aren’t, the solenoid won’t engage, and your cart will remain unresponsive. If there’s no voltage at the small posts, this could indicate a problem with the Tow/Run switch, the Key switch, or the wiring connecting these components. You’ll need to trace the wiring back to make sure all connections are secure and that there’s no corrosion or damage that might be interrupting the flow of electricity.
Understanding the controller's role in this process is also important. The controller in the Club Car IQ acts as a gatekeeper for the solenoid, and it won’t allow the solenoid to engage unless several conditions are met. These conditions include receiving signals from the accelerator for proper voltage levels, and confirming that switches like the Tow/Run switch and Key switch are in the correct position. If any of these signals are missing or incorrect, the controller won’t activate the solenoid, leaving your cart unresponsive. If everything checks out with the solenoid but it still won’t click, the issue might lie within the OBC or controller itself. They could be faulty, or they might not be receiving the signals it needs to engage the solenoid. In this case, pulling diagnostic codes, if possible, could be incredibly helpful, as these codes can indicate exactly what the controller is seeing or not seeing.
Obviously check all battery connections to make sure they are clean, tight, and free of corrosion. Poor connections can lead to voltage drops that might prevent the solenoid or controller from working correctly. It’s also important to test the Tow/Run switch, as a malfunctioning switch could stop the solenoid from receiving the necessary voltage. If you have any questions or need further guidance just ask!
