the solenoid failed I need to replace a gain. 580581


Comments

I spoke with my contact in the Tech Support department at Demco, who tells me its pretty rare for those solenoids to fail after only one year. What is much more likely is that the solenoid is not getting sufficient power, or the ground connection isnt secure enough. Instead of grounding the solenoid to the trailer frame, tie it into the ground for the trailer connector which will ensure a good ground connection. Youll also want to check the solenoid power feed and make sure youre getting a full 12-volts. If its not a wiring issue and the solenoid needs replacing, we carry a replacement as part # DM5404
