I have a 1986 Road Kings good working condition except for one pop-bumper would operate by hand on occasion… Ordered a new coil it turned out to be bad so I put the old one back in now it immediately blows a fuse when the machine is turned on… Can’t find any pinched wires… The wires were put back in the proper position… My solder joints aren’t perfect but they seem to be adequate to me… Any suggestions guys? Thanks for any help this is my first pinball game
