Ok,so I am doing my first real restore.When I got the hulk,everything was working expcept for drop targets and 2 kicker left and right.I noticed the coil on left kicker was wired wrong.When I gutted the whole unit.I had mpu checked and repaired,new driver board,new coils,new power board and all new fuses.When I started it up.It blew the fuse for the 2 kickers and drop targets.When I disconnect the left kicker and replace the fuse.Everuthing else works.As soon as I hook up the left kicker coil.The fuse blows immediately.I tried 3 different coils with same result,2 different driver boards with same result.Am I wrong in thinking,the problem is from the coil to the fuse???? Because if that coil is disconnected the other coils work great and fuse doesn't blow.Now,I did notice a resistor that the coil that keeps messing things up is wired to.Its in last few pics,says RCA.Could this be my problem? When I hook the wire up that comes from that resistor fuse blows

Your RCA 2N5875 is a transistor. It provides power to the coil and if it is bad could cause your fuse to blow.

Please do some reading at Pinwiki.

I am hoping it's that,I ordered a few new ones.If it was the board or something from the fuse on.Wouldnt it do the same when the other coils hooked to that line? The same brown and gray wires seem to feed the pop ups and the 2 kickers.When the left kicker is unplugged,everything works great.If it was the board or something after the fuse.Wouldnt it do that for all of them? That's my question,I should look for the problem BEFORE the fuse???? Is what I am asking
