Diode Pump / Valve Controls
The diode inside the JT30/50 OEM/Plug & Play Pump controls is used at the change-over ralays. The Diode blocks 12V current to prevent the motor from turning into the other direction. Replace this diode in case the valve direction is only functional to one side.
The diode, present in the Relay block is responsible for the Valve direction. In case the valve or thrust direction is only to one direction, and cannot be switched to the other direction, this diode most likely will be broken.
(Use multi-meter / voltmeter with diode check function to check it it blocks current in one direction)
In case it's broken, it will pass thru current into 2 direction, rather than the one selected at the joystick.
