Did you check the 1 Amp fuse that is under the playfield (in the general area of the flippers)?

If the knocker fires and the 2 flippers work, but none of the other solenoids work, I guarantee you the problem is related to that 1 amp slow blow fuse under the playfield. If the knocker fires, you have the correct voltages present to fire the solenoids. Double and triple check that fuse. Also check for ~43 volts DC at each coil lug. You will see the 43 volts on the coil lugs of the knocker assembly, but when 43 volts is not present on the coil lugs of the other coils, it is because of that 1 amp fuse. Then place your digital volt meter on each side of that fuse holder (one side at a time). If 43 volts is present on one side of the fuse, but not on the other side, you have found your problem.
Quoted from timab2000:If money is no object....just buy a new board from Alltec and be done with it.
Buying an Alltek solenoid driver board is not going to solve his problem if he has a bad coil. He needs to identify the which coil is bad first.
