This callout was initially to fix a non-booting issue. Simple enough; no 5 volts getting to the CPU. A connector on the power supply was dodgy. However in assessing this I noticed that the CPU board batteries had been moved to a remote battery holder. The batteries had leaked, so the holder had to go. But the CPU board was also covered in battery corrosion. It was still working, for now, but needed repair before it got much worse.


Took the CPU board, stripped the components off (⚰️ RIP to another CPU), treated the alkali, recoated the board, and repopulated with new components and a button cell battery. Working well now.


With the game now booting and working properly I could focus on the issues on the playfield. Switch in the upkicker was not responding. The actuator wire had broken off. These early Data East VUKs use very thin actuators on the switches which break all the time. Replaced with a thicker wire one.


Right flipper switch was also being weird. High resistance even when closed. Internal switch contacts had given up the ghost. New switch installed.


Replaced a few lamps, checked all switches and coils, and cleaned the playfield down to finish off. A fast, fun game to play. Love the speed check ramp feature! 🏎️
