    Hello to all forum
    In Ripleys believe it or not Every time I connect the autoplunger , the fuse burns (f21).
    I changed the coil (23-800) with new and , I put new cable from the coil to the board and then again the fuse burned. What shall I do?

    need to find the schematics , then test the transistor to see if it is blown , usually it is locked on . if you feel uncomfortable with board work you will need to get someone who can test and change the transistor .
