    Still working on my Williams jungle lord. I'll start by saying I sent the mpu,driver, and power supply boards in to Jerry clause which he ran through. Before my game wouldn't boot consistently and the F2 solenoid fuse on the power supply would blow instantly on startup. After re installing the boards, the game goes into attract, coins up and starts a game, F2 fuse no longer blows, but will not through a ball into the trough. The slingshots, lower drop targets, upper outhole kickers, and trough solenoids won't fire. The flippers and upper drops work but that's it. Any ideas on where to start?

    Voltage at the solenoids?

    After much checking, shedding a little light on the subject definitely helped. I found a loose connection at the black molex plug under the Play field. This plug is responsible for supplying power to the lower solenoids (3 bank targets, slingshots, ball eject solenoids). It's funny how sometimes something so simple gets easily looked over.
