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.
