Hi, I have a Gorgar that i recently moved. I took off the back box and removed the play field, moving each part separately. when removing the back box I tipped it forward onto the cabinet and then lifted it off putting in down standing up but there was something loose in the box. When putting it together a board screw came out so i thought that was the noise. When i turned on the machine the GI fuse blew and so did it's replacement. i re-connected all the plugs and blew another fuse so naturally i unplugged all the connectors one by one and turning on the machine. Eventually the connector running the play field lights is what was making the fuse blow. I can't find any shorts in the yellow or white yellow wires. The 2 yellows from the power read 7.4vac does that matter that it's higher than the 6.3vac that it's supposed to be? Could there be a short behind a board in the box (more than one screw rolling around)? I've read every post i could find and still tracing wires. I guess next i'll remove all the yellow wires from the top of the 20a fuse (saw in another post) and put them back one by one to try and narrow it down that way but seems like the unplugging the harness connectors would do the same thing.

Anyone know of a fix? My 20 amp GI fuse is blowing now after I got the GOR drop targets working and it blew prior to getting the magnet to work. The GOR drop targets and magnet was the last 2 things to get working and now those are fixed but the GI lights are out now. The crazy thing is the GI lights were working fine till I screwed in the C upper rollover switch light socket into the Playfield, which should have nothing to do with that.

Here is something you could try to isolate the problem. On the left side of the GI fuse there are a bundle of GI wires soldered to the fuse bracket. Unsolder the whole bunch and then with the power on and a new fuse installed, touch each wire to the fuse holder and see what lights up. The area with the short won't light up and will blow the fuse if you hold it there very long. That way you'll know the general area where the short is and this will help you find it. My guess is that possibly a screw touched a wire and grounded it or you have a shorted light socket. This method will help you isolate where the problem is. Best I can think of.

Ok here’s what is going on with my GI fuse blowing. I unsoldered all the wires and isolated which one was blowing the fuse. It’s the yellow wire for the play field GI.

I soldered just that wire back to the fuse and I Pulled all the lights out with the playfield propped up resting where the lock down bar goes. Put one light in at a time and all the GI lights worked and fuse didn’t blow.

When I go to put the playfield down near to the resting and locked in position, it starts to short the GI fuse and lights go out. I raise it up and it’s ok. So at this point not sure what it’s coming in contact with to cause it to short out. Can’t see any wires being pinched or anything obvious.

Got the magnet to work and the GOR drop target. Only thing I did prior to 20 amp GI fuse blowing was to screw the C upper play field roll over light socket to the play field.
