NEED HELP 2015 Jayco 5thr 339flqs NO power to my LCI Electronic Leveling

[Toneman69]

Used in the morning my leveler to setup , later that day I heard system beeping from the box and went to turn on and beeping stop and system won’t turn on ? Checked all fuses I could find seems like I’m missing something maybe a in line fuse somewhere ? If any one has any advice I sure would appreciate it . Thanks a lot , Tony

Assuming you are plugged in to shore power and your battery is charged, I'd unplug the power wire from the back of your control pad and check it with a electrical meter to see if it has power coming from the controller. If not, the controller is bad. Been there. Replaced that.

Do you mean unplug at the box from battery with the four 30 amp fuses or the back of the actual box of system ? Thanks again

The wire you need to check is a 4 conductor (green, black, red, yellow) inside a black corrugated wire cover that leaves the brain (controller). The controller also has the power wires from the battery and the 6 plug in wires from the 6 jacks. When the wire leaves the controller, it travels to the control pad. You will need to remove the control pad and unplug this wire in order to check for power coming from the controller. In my case, there was a message on the control pad that said "comm error check wiring". Meaning there was a communication error. The unit would not turn on. I traced the problem to the controller by checking the voltage of the wires from the controller to the control pad. There was no voltage. LCI replaced the controller. Problem free since then.

My problem was the ground wire for the 12v to the control wasn’t crimped in the wirenut and just “fell out” after a couple times
