Hi all,

My son was playing the machine and then the flippers stopped (and bumpers etc) the switches seemed to work so I checked the back panel cabinet (see attachment). The connected burned out apparently.

My experience with pinball maintenance is limited to some simple soldering work and replacing simple parts. So bear with me
If I've replaced the connector are there other usual suspects to check out or will this likely be the problem.

Thanks!

Ok will check the fuses and look further for other pointers thanks.

You are right. I've looked back some assembly photo's from a few weeks ago when I've purchased and moved the machine. This connector was a bit black from what I can see.

Edit 3: found a blown fuse F112 - 220v 7A

After spending seven 7amp fuses I have found a problem in the diode bridge. One of the four internal diodes gave 0 ohm both ways so it shorted the F112 fuse out. Waiting for the replacement diode bridge to arrive.

It looks worse than it is. The diode bridge came in today, soldered it into place and Dirty Harry is back

Quoted from slochar:

Looks like you pulled the pads off the top of the board as well they seem to be on that rectifier, so you will have to repair the board too or use jumper wires.

I’ve soldered the bridge both sides. Think this will cause troubles down the road?
