I'm restoring my WH20 and I'm currently troubleshooting the G.I. lighting. Since this is my first time ever trying this, I'm pretty confused. So, here's what I've done:
-Replaced a blown fuse, which brought back the backbox G.I. and one of the two coin slot lights, too.
-Checked connectors J120 and J121, both have pins intact and no burning.
-Checked J115, which seems toasty on pin 2 (second most from the right). Not sure if this is contributing to it.
-All fuses have been tested and are good now.
-Connectors have been reseated. No dice.
-Playfield still has no G.I. at all.
Where do I go now? Do I just crimp that connector? Anything else I should be looking at? Also if any of you guys have part numbers for the connectors/heads/crimping tools, I would be super appreciative. Gotta say, restoring these games has quite a steep learning curve but holy crap is it exciting when you fix it!
