Question about sling shots on Marvel Heroes pinball.

[Stun Runner 87]

Hello,

I have a second generation Zizzle Marvel Heroes pinball machine.

Everything works great on it, except there seems to be a problem with the two slingshots above the flippers.

They work, however they seem to continuously go off on there own without stopping.

Is there a way to fix it or get it to stop repeatingly going off. Somtimes they also seem to go move whenever pressing flipper button also.

Is a wire hitting somthing wrong?

 

I am aware that the Zizzles were cheaply made and not truly real pinball machines.

Although when working right. They can be a little fun.

Any info would be helpful.

Thanks.
