I have a stuck input on KHU. I replaced the board in the c.o.p and the main relay board in the controller. The only board left is the software board. Magnetic switches on cartop are ok and have been taken out of the equation. Any suggestions?
best thing for a 330a and trx5 is the double reboot ram flush. on inspection push the reset button and as soon as the red light turns on again push and hold the reset for 5 sec. this clears the ram that is probably held charged by that cap.
