Hello. The trough on my medieval madness is kicking out an extra ball about 15-30 seconds after the first ball is ejected. Is this typically a problem with the driver board located under the front of the pf? Or is it an opto issue? I checked alignment on the optos and they appear to be in good shape. Thanks, Justin

I would check to make sure ALL the optos are working in the switch test. Also make sure the shooter lane switch (I can't remember if it has one) is working.

It's not a driver board issue; I've only ever seen a switch or programming problem cause that.

Besides optos and shooter lane switch. Your ball jam opto, last one the ball goes by going up, which when triggers gets an extra kick.

Pull out your manual and look at the switch matrix and find it, then check other switches on the same row and column for shorts to switch lugs or wiring.
