Recently I have been restoring a 1980 Xenon, adding new boards and a new playfield. Everything has been working all well(meaning the game works and everything is restored) except the left flipper. A connection is getting to the button on the outside of the machine but the flipper just won’t flip. I thought it would be an easy fix and just assumed it was the solenoid since it’s been in need of a new one, so I switched a new one in but it still doesn’t work. I’m guessing it has to do with something in the head of the machine but I can’t find anything. Any suggestions?

1st check the voltage at the coil with a meter. The power side (usually yellow wire) should be +/- 43 VDC with black lead to ground. 2nd check the cabinet switch, set the meter to continuity and attach leads to the two tabs on the flipper button switch. If it beeps when you push the flipper button it's good. 3rd, did you install a new EOS (end of stroke) switch? Report back.

It's a simple circuit. One side of the coil has 43v the other gets a ground. Take a test jumper and short the game ground to the unbanded side of the coil diodes. If it flips the coil is fine. The ground circuit goes from the rectifier board, through the cabinet switches, up to the sol driver board, through the flipper relay and back down the playfield cable to the flipper coil. There is an open in that somewhere that you can prove out with a strategically placed ground jumper.
Check the solder to the relay and the connector next to it. That's were the fail often is.
