Got a STTNG a few weeks back and all worked great until the other night. During battle sim the left cannon wouldn't fire when i pulled the trigger, (right works fine) but with enough pulls it eventually fires...sometimes. Obviously something is shorting somewhere but since my electrical testing skills are at a 2nd grade level i don't even know where to start. I do have a buddy who is good at this type of thing but I want to give him some direction when he can come over to help.

Any help anyone can provide with starting points to check would be great.

Thanks!

Went through switch test mode and even adjusted the trigger switch, everything operates as it should and still no consistent firering. The noise sounds the flashing light in the cannon goes out but the ball remains till it almost gets back home then shoots the ball.

The machine is registering the trigger being pulled, but the solenoid is not shooting when trigger pulled, only when the cannon almost gets back home???

Good news is, everything works, just not how it should. Any other suggestions?
