When I powered up my game, the Vengeance toy immediately dove down to the crash position and locked into place. It also blew fuse f8. I pulled it out of the game, made sure everything was working freely, tested my transistors and didn't find any blown, replaced the fuse,
powered it on again, and same result, ship goes straight into dive mode, but I cut the high power before it took out the fuse.

Game works 100% without the Vengeance installed. Ran it through the tests and put some balls through it.

I've exhausted my meager troubleshooting skills. Can anyone point me in the right direction?

Found an old thread that steered me in the right direction. Replaced transistor #53 and it fixed the issue.
