New problem with this 1046.. Feature light won't light..

[Amechanic]

Ok.. this one has me baffled  .. The top left 7 on the feature unit won't light when I play a second coin. I have tested and replaced the bulb, that's not my issue. That same light does not light when the 4th coin is played either... BUT it does light if you hit a 7's jackpot on line 4?? What am I missing?? This light was working yesterday till last night. Go figure I was just getting ready to wrap this one up and get paid for the repair.

Two more pics. One playing only 2 coins, second is a 7's jackpot on line 4 with light lite!

Coin in lights and jackpots may have separate circuits. Check for 1 common and two additional wires.
Could be a break in the circuit between the coin in light (left of the bad 7 socket) and the 7 socket.
Someplace on one of those bare silver wires or right at the socket solder connection.
Post a photo of the back of the board of this area, if you get a chance.

Think I've traced it back to the beau plug on the feature unit. I'm currently looking for where I put my bottle of beau plug male and female connectors I saved from busted plug. I want a male pin to test/ check the connection pressure of the female connectors. I bet I find at least one loose.

Ok. These things are a bitch. Finally traced the problem to the relay for the 4th line JP. There are 3 sets of contacts in the that relay that have a normally closed switch. The center contact was my problem. Cleaned it and the light worked.. The bad was that the center 7 and lower right sevens both went out. Took my time cleaning and adjusting all those contacts in that stack and, and.... Yes I now have a fully working set of feature lights. One last thing to work on is the buzzing coin scavenger coil. Hopefully it won't be too much of a pain to keep quiet. The diverter is not noisy, just the scavenger coil. Then I can ship this thing out.

One more pic of the machine lite up.

I like that Belly glass, it's so much like old Vegas!

Maybe you can keep this machine, swap the owner with a GameMaker or PE+ machine?

If it were mine, I would trade it. Not going to find many in nicer condition. Cabinet and chrome are almost perfect. Just a few small flaws in the glass.
