Hey all.

I'm having an issue with my back plastic GI by the back of the playfield. All other GI works on the game. The back GI is off normally before the plunge and once the ball hits a switch the upper GI on the playfield turns on( I believe this is when the BackPlastic GI should turn on as well). The flashers on this section works perfectly.

I checked all fuses and they are working. Any suggestions here? I was reading something about a relay that can go bad which causes this problem. Any help would be appreciated.

Thanks,

Pete

Ok ill take a look at that tonight when I get home. How would I go about testing it to make sure that really is the issue?

All new LED bulbs were put in so I can rule that out.

No it didn't work with the original bulbs.

I just ordered the new relay so hopefully that will fix the problem. Will update once I get they installed later this week.

@Jhanley - I believe the machine operates that way. Let me check when I get home to confirm.

@Lostlumberjacks - are you talking about reflowing solder on the male connection at the relay board or the actual board with the lights?

I believe there are actually two relays. There is one all the way at the bottom of the playfield and another one on the left next to the hinge. See attached picture. Does anyone know what this one does?

I already purchased a new one but will try swaping it out tonight.

The GI lights on the back of the playfield turn on and off like they should. The GI on the back plastic under the flashers never turn on. The flashers work perfectly.

Yes the Lightning strip GI does not turn on.

Ok two questions.

1. How do I test the voltage with my multimeter it's been awhile. Do I turn the machine on and stick the red lead into the socket with a wire and then touch the black lead to a ground? If there is proper voltage I should see 25v's on both the purple/white and purple connections?

2. I'm trying to trace back the purple/white and purple wire to the board so I can test continuity. Having trouble doing that. Do you know where these two wires connect into the back box?

Ok so I should stick the black lead into the purple/white and the red into the purple and see if I get 25v?

Ok I did that and get no reading. Assuming I am doing that right I need to find out where the purple wire connects to the backbox and test for continuity? If I have continuity then it could be the connector on the board?

Yes. Here is what I'm doing.

Thanks for the help thus far jhanley.

Does anyone know where this wire traces back to the backbox or what's the next step here in figuring out why no power is getting through to this wire? I have no other issues with my GI except for this area.

I actually have a new interconnect board and will swap that out to see if it helps. I replaced all fuses that I had but needed to order a few new ones that I didn't have on hand. will swap those out. Will report back after I swap the ICB and replace all fuses.

Is there anyway to check on the manual which fuse would be responsible for that part of the GI?

I will take a look into this when I get home tonight and fill you all in. Thanks for all the responses.

Jhanley was right. See the picture below. The wires purple/white and purple connect at a Molex. What was confusing is that the gauge of wire is different in each end. I found the other end bundled and disconnected from the Molex inside all the other wires. Took me about 10 minutes to find it and redo the Molex connections.

Thanks for all the help on this one guys. I'm sure I will have a few more questions to come as I start to do my PF swap!
