Hey FP, if you check around line 13 of the schematic, you should find the “add ball count unit” coil. That activates with a motor 1a switch when the AX relay is activated. Line 14 has your “AX Reset” coil. I would start with checking the long line of switches that need to close to activate the AX reset.

Or possibly check the adjustment of the AX assembly. My Sky Jump gave me fits with this.

I would think that the switches in AX and motor 1A are good because the ball count coil is firing. My guess would be that you need to get AX reset to energize to stop the ball count from firing. Can you manually reset it to see if the problem goes away? Good luck.

Ok, also, how about the contacts at the 6 position at the ball count unit with wires BR-WH-RD and OR-WH-RD? Is the disk positioned correctly to make contact?

Right on Rolf! Thanks for the safety reminder. I troubleshoot live circuits quite frequently at my job, so I am fairly comfortable with having my machines on when I work on them. I sometimes forget that most others don’t do that type of work for a living and may not be aware of the dangers that are present. Good looking out!

Your pin has issues man. Glad you are making progress though.

The only slow blow I see on the schematics is the 5 amp before the on/off switch. I assume the rest are standard.

When I disassembled my Ship Ahoy playfield I lost a small lock washer. Wasn’t a huge deal. When I put the game back together, I kept blowing a GI fuse. Eventually I found the problem, the lock washer had fallen into a lamp holder socket and created a dead short. Probably not your problem, you never know.

Thanks for the update, I like hearing that things are getting figured out.
