I have just installed the above in a Potterton Suprima 60, but it keeps blowing the main 3amp fuse in the electrcial supply spur after abovce 20 seconds. I have checked the mains wiring onto the terminal block and also onto the PCB both OK.
I know the next stage is to check for shorts on Pump, Fan & Gas Value, but how do you do this? These were OK before PCB was replaced. I have also checked the the PCB fuse but cannot see if this needs replacing.
Can anybody help me?
