Ball Launcher is very weak on Getaway!

[AndyB53]

Just about finished the Getaway HS2 but one problem I cant figure out is the weakness of the Ball launcher! It is working but is very weak and barely gets the ball into play. I have checked the Solenoid and it is the correct one (14789) It is not jammed and is completely free. The fact that it operates at all means the cabling and Tyristor and it's transistor that fires it must be ok? and it operates on all solenoid tests etc. Is there a hidden setting somewhere. It is really odd! Every other solenoid is operating 100% so voltages must be OK Anyone got any ideas?

Is it making good contact, i.e. transferring solenoid energy to the ball?

Have you taken coil off and measured the coil to what it should be? I cannot find that coil on the chart, but it is pretty definitive.

I had that once and it was the 2 pieces of metal on the guard that goes over the shooter lane to hold the ball. They were both bent too far forward so when the coil was firing it was barely coming into contact with the ball

Now Sorted! Looking at the Schematic there is a High Current Driver Board under the playfield the Molex connectors had the usual "dry joints" DOH!!
