Yeah here’s what mine looked like when I took it apart. The connector with pins needed replaced same as the board needed repaired ugh

Ok, first my J115 is being redone (both the connector/pins and the board - all burnt there) -but my J120 and J121 look very different from the photos above.

Is this a diff version/rev?

Also - my GI & Back Box lighting is coming from my J115 connector (which is being replaced, but that's what led me to find the issue).

What's up? As mine "looks" factory, has one of these others been hacked to just get power to the lights? Why didn't they go back to using J115? (Or perhaps it too was burnt, so this was the quick fix?) Just throwing that out there, as I'm confused. lol (But I'm a newbie, so that happens a lot!)

Here's more on my J115 connector issue...but again, this has been replaced with a new connector and pins and the board is now being fixed as we speak (text?) lol so hopefully my GI issue is resolved soon. Just wondering why the noted above differences?

Ahh! Thank you! Now it makes sense.

Quoted from Schwaggs:

The red connector in the picture above is most likely a replacement connector. Most every game I have seen has white/cream plastic connectors.
J115 is the INPUT to the driver board for the GI. This is power from the transformer into the board.
J120 and J121 is where the power leaves the board and goes to the actual backbox or playfield.
All 3 of these connectors are subject to burning/melting.

Question- got my board back and the GI is all working and the backbox lights as well. The backbox flashers do not work though

Based on some hacks I’ve seen in this machine I’m thinking the original wiring is not correct. (I’ve added some photos of the diagnostic screeens but not sure it’s wired that way )

What I’m looking for is what PIN number on my J115 would feed power to J106 pin 1 (I think. It’s the one with the red wire)

I’m thinking I may have done a bad pin job and don’t want to take them all apart on J115 Just the one that feeds power to the flashers in the head

The diagnostic shows it coming from J107. But I’m Almost positive it’s this wire from J106

Will do. Before I sent the Board off for repair they did flash. (Board is fine. Perfect). I’m the one that had to install a new connector and pins on all of the yellow wires on J115. The other flashers work and fuses “look” ok (I’ll check when I’m home to be sure ).

I was just thinking I may have not connected a pin correctly when I re- did the connector

But the landing points as shown on the screen (see photos ) do not match how it’s really connected

So not sure which pin to check that may feed power to the backbox flashers.

Ugh!!! I’ve been testing with the door open! Lol. It can’t be that easy! I’ll def check that when I get home. Thank you!

#23 5 years ago

Once home realized didn’t matter. I was testing thru the diagnostic so the door would have to be open. So that was not an issue. And playing several games now they’re not on when the door is closes either

#25 5 years ago

Well “dumbass” call me a dumbass. Tracing the wires all the way back I found that one spool connector (J126) was stuck behind the board! Not connected of course. Ugh. So after connecting -“ all is 100% working !”

Thanks to all sorry for a fire drill!

Now time to mod this thing
