Can someone help me out on my JP? The lower half of the back box lights, the top left corner GI lights, and the spotlight on the Trex are all out. There is no power to sockets on the volt meter. I checked the fuses and looked for anything obvious but got nothing. Not sure how to diagnose this. I’m assume they are all part of the GI and not on the lamp matrix since all the other lights test out correctly. Love this game but it’s super dark without the lights. Thanks!

Chalky -
You have a break in line somewhere. Verify you have the twelve volts on the lower lamps - keep working your way back toward the backbox until you find your voltage, then you will know where the issue is.
Also verify the power is going thru the Z connector - that's where I had an issue.

So yeah...not sure how I missed it the first time. Half the Z connector is burned to a crisp lol. It was facing in and I thought it was just pen markings on the connector as some of my connectors have been tagged. Nope, fried. Followed it all the way back to the PPB and the connector there is fried to a crisp on the underside where it locks and was HOT. Disconnected everything and saw that the PPB must have been previously repaired as those jumper pin headers were clearly resoldered poorly on the back side which caused a worse short. So I sucked it up and ordered a new PPB. I'll have to rebuild all the connectors on this harness but hopefully when I plug the new board in the backbox and the missing GI lights will all work again.
