Double Jackpot Haywire not working

The solid blk wire is pictured below at the ps connector & again at mother board power connector J13, pin 6. Mine shows 6.4V.

I just put a light to the rear of the cabinet where the MPU plugs in. The connector and the chips near it are acid damaged as well. I'm guessing that's the part I'm needing to replace. I'll report back when I get a new one installed.

Do you mean the mother board, aka backplane? Let me know if you need one.

I purchased a replacement backplane/motherboard and still have the exact same problem. I went ahead and tested volts yet again and I'm still not getting that 6-9v for the game. Where is it coming from? I have good 13 and 25v from the power supply which is the only two volts it puts out.

My previous reply (#20) was pretty specific. Here are the same pics with arrows added. If you do not have voltage at these points, repair or replace that power supply. It's the same wire in both pics. It should be easy to test at the mother board connector.

I just received a replacement power supply. I have the exact same results. I have the 13 and 25v the power supply puts out. The only two voltages that this power supply puts out. It doesn't have and output for 6-9 volts. Obviously there's something wrong with what drops down one of the other two voltages.
