RBON autoplunger problem

[Panagiotis Salesiotis]

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?

check transistor

how will I do it? and how will I find what it is?

 

[luch]

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 .

yes that is a transitor , but you need to get the proper one , i do not know which one you need .

rbon use a mosfet transistor , wpc games use a darlington . irl 540 is a good replacement
