I have a JLG 1930. I have no power to the controller on the platform. I checked the key switch at the control at the bottom of the lift. I have power and the lift will go up and down by the lower controls. When I switch the key to power up the platform the controller doesn't light up or function. I don't see any issues with the wires going to it. When I took the lower control apart I Don have any red lights on the circuit board when I switch the key to power the platform. I have a red light when I switch the key to power from the lower control. Is there a way I can check power to the cord going to the platform? I'm also thinking a possible issue with the emergency stop.

I started have issues two days ago. When I would raise the lift from the controller on the platform I would lose power. I got power back from an unknown reason and started to use the lift again. But I would lose power a couple more times until finally yesterday I couldn't get power back to the platform.
