IZE FUSES GO INTO A BALLY STRIKES AND SPARES PINBALL MACHINE

Several Star Wars pinball machines shown at the link below:

The two most common problems with solid state pinball machines are blown fuses and bad connectors. A third common problem is leaking batteries that eat away the copper traces on the motherboard. I assume that you have checked all of the fuses. You can try to unplug and replug each cable connection in the backbox. This can sometimes clear intermittent contact problems. In other cases metal fatigue within the connector make for poor contact and the connector may need to be repinned. Also stress on a male connector pin can sometimes cause cold solder joints. Many solid state machines had rechargable battery packs that were soldered onto the motherboard. Over time these would leak acid onto the motherboard and cause issues. If none of these suggestions seems to help then I suggest that you pose your question on an active pinball forum like www.pinside.com. There are many people there that can help you debug the problem.

Pinball problems are commonly discussed on pinball forums. For your case go to http://pinballbash.com/forum/index.php?topic=2526.msg23570#msg23570 and look for a very long append from VisitorQ. He gives a nice detailed description of the possible causes.

Bally uses an end of stroke blade switch for their flippers. Lift up the playfield and look for the blade switch associated with the right flipper. If there is a wire off or they are broken then resolder it or change them and it will be fixed. If you don't see any problem then put a jumper across the connection and see if it works. DO NOT LEAVE IT ATTACHED. If it worked then change the blade switch. Other possibilities are a bad solder connection on the Solenoid driver board or a bad flipper coil itself. Hope this helps

I need to know what machine are you working on? Different era machines have different answers.

the standard size is 1 1/16" there are some machines that use smaller balls you can check online for what size you should use for your particular machine.

Bally made Fireball in 1972 and 1976
They made Fireball II in 1981 and
Fireball Classic in 1986
some of the manuals can be downloaded for free
from the net just search IPDB on the web
