Oops.. Didn't double check.
So the solenoid is not recognised in the solenoid test, and the A 3 .21 Setting is missing.
Can someone who owns a TZ remove the connector to the Knocker, and test to see if "solenoid 7" or A-3. 21 is present ?
Sounds like an open wire to the coil.
I also believe he has checked continuity between coil and driver board - checks out OK.
Then it has to be the driver transistor - which I find hard to believe. This coil has to be the least "fired" coil in the game. The fact that the coil test skips "solenoid 7" is a fair indicator that either the ROM / Setup is incorrect, or there the driver transistor is stuffed.
I guess an option is to set the game to factory defaults ?
