HWH 325A Circuit Board
Hi all, Has anyone removed the circuit board from the control box on an HWH leveling system? Mine is a 325a system and I can see, and have removed, 2 screws from the bottom edge of the board but it...

Connections in the connector could have arced and welded them together! Just thinking!
As you probably saw, C1 connector is main power!
What is issue with your jacks?
The left rear jack will not respond. When I push the extend button for the rear jacks only the right one will move. If I switch the wires on the solenoids, I can make the left one extend but now the right one won't.
I've probed the circuit board at the CN2 connector and pin 5, which is the +12v signal for the solenoid on the LR jack reads 0 volts when the button is pushed. Pins 8, 9 and 10 which provide +12v to the other 3 jacks measure correctly. I've verified there is a good ground at the connector.
The LEDs light up correctly.
I don't know where to go from here except to remove the board and inspect it looking for broken traces or solder joints. That's why I need to remove the connectors.
