The auto kicker in teenage Mutant Ninja Turtles is not getting the ball into play with good reliability. Half the time, its a roll-back and then there are two balls in the lane for multi-ball.
Current solenoid is a DE 22-600 and it just does not feel like it has the power. I tried a second 22-600 solenoid with the same results.
Is there a stronger solenoid I can try?
I saw were action pinball said a 23-750 solenoid would be more powerful so when I removed a known good 23-750 from another machine to test, it performed even worse. Shortly thereafter, the transistor driving that solenoid shorted out. So would moving to that different solenoid really cause the transistor to short?
Is it possible the transistor was degraded to the point where it could not provide the correct power to launch the ball? I am going to order new transistors but also want to order a stronger solenoid as well...if I could just figure out what solenoid to order.
So can anyone tell me what the strongest solenoid is for the auto launcher function. Better too much than not enough power.
Thanks for any assistance.
