Quoted from YeOldPinPlayer:
Right drop target? The solenoids are shown on page 9 of your manual. The only connection I see between the three you listed is the ramp and drop target bank both use power line connector J10-P9/10 (pins 9 & 10?).
Did everything work before you started adding mods? Do any of the mods you added use the wires going to the solenoids that are now acting up?
Do you have continuity from the connector to the solenoid? Example: Ramp uses connectors J10-P9/10 (power, YEL-VIO wire) and J8-P6 (control, BRN-GRN wire). Test continuity from those connectors to the solenoid.
Thanks, I have to use a PDF version of manual, but yeah I already spotted that with the shared wiring by eye and traced it back.
I don’t know frankly, I had a bit of work to do as as an import machine before firing it up , so I just kept going to get the back box led installed ie removing the ballast etc (which piggybacks a different circuit as per other mods), topper, prison tower - rest were non electrical. I will definitely test continuity today from the power driver board today and go from there with the multimeter.
EDIT: After testing continuity and finding no issues, I started looking more widely. I should have know, sometimes its the most obvious things which don't appear to be related at the time. When I got the machine, both of the small wires on J2 were loose. I had thought I'd reseated them in the connector, upon checking them it turns out they must have still not been making proper contact still. Soon as I got them making proper contact again, bingo problem gone and we were away. Finally got some good games up. Clocked 205m in my second game. I'm really getting to see why people really love having TWD in their collections. Excellent flow and so much going on, the amount of modes you can stack, the multiball, etc.
