Hello everyone,
I'm Kristof, I live in Belgium and I got into the pinball hobby only recently.
A couple of months I bought ago I bought a Road Kings that was working but the game wouldn't start. After replacing the column transistor that controls the outhole switch, things were working again.
Until yesterday. When I pushed the start button to start a new game, the machine went completely nuts (garbage on the displays, hum through the speakers, flashing lights, random resets,...), so I switched off the machine immediately.
When I opened the backbox, I noticed a fuse was blown. The fuse blew on the right side, not in the middle. I indicated the blown fuse on the photo below:
As far as I know, this is the fuse on the circuit for 50V non-flipper coils. Is that correct?
After removing the fuse and switching the machine off and back on for a couple of times, things were working again. (I haven't placed a new fuse yet because I'm out of 2.5A fuses. I will get more soon) The only things that were not working were the Upper Left Kicker and the Power Kickback (left outlane).
However, the machine did reset on some random occasions (about 2 times in 15 minutes). I don't know the cause of this.
Then, today I wanted to measure something with my DMM. I switched on the machine and wanted to put the black lead of my DMM behind the ground strap in the backbox. When I touched the ground strap, the machine started to go completely nuts again (garbage on the displays, hum through the speakers, flashing lights, random resets,...). The red lead of the DMM wasn't touching anything. I quickly switched the machine off and I haven't tried switching it on again, because I'm afraid of damaging anything.
Does anybody have an idea what could be the cause of all this?
Thanks in advance!
