Re: 17pw26-4

You know how you tested the fuse ? Your meter beeps if its good, same with a shorted component if a part is shorted your meter will beep when you probe the legs of a device. To test the fets go up and down the board in diode mode and probe the pins of each fet.

thanks reeceyburger. will give that a try, need to head out now, i noticed it was a bit discoloured underside near the ones at the top, so ill guess thats the ones to start with

Re: 17pw26-4

Glad to help, normally the top ones that blow hopefully they did not take out the resistors too if so not going to be easy.

Re: 17pw26-4

i wonder if its worth also replacing that controller ic SEM2017 Ic as in reece thread post 82 it may save more parts blowing and wasting money etc

Probably is tbh Vince, mine was sending a crazy Vcc voltage to the fets causing them to blow when ever it did meaning the controller had failed intermittently.
