I'm trying to help my aunt with an Allied Leisure non-commercial model of Rock On.
The machine powers on, displays working fine. When you hit the game start button, the machine tries to cycle through the reset sequence, but ends up with the reset relay just repeatedly clicking because the ball kickout solenoid doesn't fire, and the ball ends up just sitting in the drain trough. If I manually cycle the kickout to move the ball out of trough into shooting lane, the game is recognizing that and the reset relay stops.
However, none of the other solenoids on the game, with the sole exception of the chimes, fire during the game (including pop target resets, flippers, or slingshots), even after launching ball to trip the shooting lane switch. Some playfield switches will work and trigger scoring, but it's less than half of them. Chimes and displays are working to indicate when scoring is occurring.
Anyone familiar with any known issues on these that I should check first while troubleshooting this, to hopefully save me some time? I've already noticed the fuse holders aren't the sturdiest, and a couple of them are loose or broken, so I'll be replacing those, but they all buzz out with the DMM so I'm not sure I can blame this all on them (yet). The machine is about 4 hours away from me, and I'll only get to look at it during holiday trips the next couple months, so hoping to have as many ideas lined up for what to check as I can, to get as much done per trip as I can.
appreciate any advice/suggestions you all can offer!
