This 1971 Bally Firecracker is my second machine and so I'm still learning (slowly!). I have fixed a number of the more obvious issues and now getting to the more tricky stuff. Currently I'm stuck on this issue:

The bonus score accumulates no problem (meaning it moves from the 1000 lamp to the 2000, and so on)

The bonus score gets added when the ball lands in the on-field kick-out "bonus" hole (lamps count back down to starting point of 1000 and associated score counts up on score reel)

However, when the ball drains, the lamps count back down to 1000, but no score is added the reel. The rest of the mechanism works (moves to ball 2, and ball ejected).

So, I'm not sure where I start given the process is working on the kick out hole, but not the out hole. I have a schematic (but not pdf - will I need to scan and upload for the experts to help?)

Hope someone can point me in the right direction, I'm loving fixing this machine up from a complete non-starter, but have come to a bit of a standstill on this…

Thanks in advance.

Hi, yes I should have marked this thread Resolved (have now) as I had posted it in another forum and someone kindly linked to a youtube demonstrating the bonus hole versus drain. (Doh!)

Ten months on I still enjoy playing this machine - one because I was so pleased with myself for getting it all working, but also I love the Firecracker "random" feature - so clever for the time.
