I got this Williams Jungle Lord pinball machine in for repair.

It has not worked in many years and need a complete overhaul.
The batteries on the MPU had leaked and caused much corrosion on the driver board under it.

I have not tried to boot it up yet due to the leakage, and i also want to repair the rectifier board first to be sure that the voltages are correct.

The rectifier board also has some dubious repairs that i have to fix. 🙂
