Bedroom slide was having issues in the gearbox. I installed a new Lippert motor/brake and gearbox assembly. That fixed the mechanical issue I was having but am now experiencing and electrical issue.
Note: the replacement Lippert motor was listed as 20amp whereas the original was listed as 10 amps. I brought this to the attention of Lippert tech support who said that would net cause a problem.
The problem is this… when the slide motor brake is mechanicaly disconnected, the slide moves in and out freely. When the brake is reinstalled, the motor cannot move the slide. The brake is clicking like it is working but it is not.
The brake and motor are wired together. When the brake is physically disengaged, the voltage at the motor and brake is 14 volts. However, when the brake is reengaged with the motor the voltage at each of them drops to 3 volts.
One final test that we did was to power both the brake and the slide motor with a Milwaukee 12v battery. It both released the brake and moved the slide motor. That tells me that the problem is not with the motor or the brake or anything related toe the mechanical operation of the slide.
I must have a problem with the power or ground circuits. I don’t see any relay or solenoid in the system.
Does the wall switch power the motor and brake directly or is there a relay somewhere. If there is a relay, where is it located.
Any assistance would be greatly appreciated. I’m getting grayer by the minute.
