Quoted from Willy39:I was playing good old frankie when I notice the auto-launch plunger on even though there was no ball in the shooter lane. I shut down the machine and checked out the coil to the auto launch. One end of the diode broke off and was not connected. I actually ended up replacing the coil and that had a new diode installed. I power on the game and it does the same thing. The auto launch coil is activated as soon as I turn on power to the game. So would my next repair be the transistor tip? I attached the page from the manual but would I be replacing the tip at q44? Just want to see if that seems the next logical thing and if that is what would get damaged if a diode broke on a coil. Also let me know if you have any other things I should check as well. Thanks for the help!
Yes, you can test that with your dmm first, but it sounds bad to me if its locking on. Note that q44 is on the cpu while q5 will be on the ppb board (tip36c)
