check the handle solenoid, sounds as if it is stuck in the energized position. when energized the plunger is pulled up into the solenoid, that allow the handle to be pulled, after the game play, the solenoid is de-energized ,the plunger releases and stops the racket pawl from being used.
remove the solenoid, lube the moving parts, and disassemble the solenoid so you can stretch the spring, this will give you a better release and thumping sound when the reels lock in place.
hope this helps
I have replacements availalbe.
