2001 48 volt solenoid resistor overheating


New Member
I have recently installed heavy duty wiring kit with hd solenoid, f and r switch and new speed controller. With key off and ground wire connected, the resistor on large terminals immediately gets hot and starts smoking within about 5 seconds. Any info or idea on what may be causing this?

Did you replace the DIODE and if so check for correct direction on it. Also are you sure the resistor is CORRECT UNIT?
Could the solenoid be defective and or incorrect control wiring at solenoid? Really sounds like wiring problem of some kind.
