This control is equipped with an internal resistor, and installing one on the solenoid could cause damage to the control.) CHECK THE CART WIRE HARNESS: Check the connectors on the wire harness for corrosion, loose, broken, burnt or missing pins. If pre-charge resister is installed, please remove. Be sure to check diode functionality with VOM prior to install. (If suppression diode is present, the non-banded side must go to the wire from J1 pin 17 from the controller. Remove jumpers and reconnect solenoid wiring from the harness. Meter should jump from infinity to LESS THAN.3Ω. Attach jumpers from main battery positive and negative to the coil (small terminals). Connect VOM leads to the main solenoid lugs. This should measure 100Ω - 250Ω (depending on solenoid type). CHECK MAIN SOLENOID: Disconnect all wires from the main solenoid. With motor disconnected, measure F1 to motor case. With motor disconnected, measure A1 to F1. This should measure approximately BETWEEN.8Ω and 3Ω. With motor disconnected, measure F1 to F2. This should measure approximately BETWEEN.2Ω and 2Ω. With motor disconnected, measure A1 to A2. Subtract this measurement from each test below to get your true measurement. To test the resistance of VOM leads, please touch the meter leads together. WARRANTY WILL BE VOID If These Steps are Not Performed Before Installing The Control STEPS TO PERFORM BEFORE CONTROL INSTALLATION CHECK MOTOR WINDINGS: Set your VOM to RESISTANCE (Ω).

An analog or digital volt ohm meter (VOM) will be needed to perform these checks. The following steps must be taken to help diagnose a possible cart fault or faulty controller. Upon installation, you may encounter problems that may, or may not, be due to a faulty controller. 1 Curtis This sheet is provided to aid in the installation of your remanufactured CURTIS controller.
