Quoted from Wmsfan-GAP:So I'm working on a recently acquired Target Alpha. I've gotten several issues corrected already, but still have a couple of issues left. Not sure if they all kinda relate to one another or not.
Outhole (ball return coin)- solenoid will not activate to kick ball out. Switch is fine- if I have any bonus points earned, the ball on the switch registers to activate the bonus. Solenoid has been tested- it works if I jumper it on say a slingshot, and moves freely. What triggers ball return coil activation? Something that may go along with this issue, is that the balls are never counted. If i manually move the ball thru the ball return channel to the flipper lane and play, when the ball drains, there is not any ball counting done- i could play forever. There is not even ball in play lighting working- yes lights have been replaced with working ones.
Any suggestions on what to look at?
Have you cleaned and lubed the bonus unit? My Jungle Queen had this issue and it was an issue of one of the springy contacts not making good contact on the stationary rivets? Some degreasing and adjusting fixed it.
