Hello everyone,
Kinda going nuts here. Don't really know what to check next. Have a Mr. And Mrs. Pacman 5hat will start fine, run all flashes, sound works and all the under playfield lights work. However, no solenoid except the knocker will work. Checked the under playfield fuses, and have a vector working I've been crossing boards with to eliminate boards as the issue. Checked the bulbs for the playfield expander boards. They light on first button press, but the bulbs don't light on solenoid test, nor does the expander board under the playfield click like vectors... wondering where to look next. Any guidance would be helpful.

So a bit of an update. And I'm going through the pinwiki now. However I do not have 43v at the flippers or at the fuse holders. I have a new alltek solenoid driver in. And its showing no issues. 43v kicking at its test points. However I've pulled p1 and checked voltages at the two bottom pins,(Labeled lt-flipper and rt-flipper) and get no voltage when a game is started or when put in solenoid test. I'm looking through the manual. Does the 43v pass through the s&t board? It says on the troubleshooting flowchart to change this board.

So I've checked J1. Using both solenoid boards, and got zero's... though the test point is revealing 43v clean. Is it possible I have 2 bad solenoid boards? I cross tested them in vector and both work.. I gotta be missing something. Is there a rectifier board between these? One of the boards in question is a new altek that is showing good on its cycle tests, and the knocker is working. The J1 connector is showing connectivity through to the flippers.

Success! Thanks guys, once I disconnected the large trunk of wires and got to inspecting from J1 up I discovered a break around the upper playfield flipper. Was getting 23volts at the main pair of flippers discovered the partial break and patched it. Bam! Solid 43 all around now. Thanks guys!
