I’ve been working on a Bally Bow and Arrow for a friend of mine for the past few weeks. It sat in a storage area with no climate control so the whole thing was pretty messed up when it came out of storage. I was able to get a lot of the basic stuff fixed, but I’m tearing my hair out trying to figure out the last big hurtle.
All of the lights on the playfield and door work perfect. However, none of the lights in the head work. None of the general illumination lights work, and none of the during game lights work. I’ve traced almost everything back in the schematics thinking it was a switch that wasn’t working, but I couldn’t find anything.
I did have a small stroke of luck after cleaning the male portions of the Jones plugs leading to the head. They were very dirty and looked like a grey metal. After cleaning the two plugs in particular for general illumination, the lights in the head lit up. They stayed on for about 30 seconds before they turned off and refused to turn back on. The fuses are new, the fuse holders are not, and they all are okay even after the lights in the head turned off.
If anyone has any ideas or guidance I would greatly appreciate it. I do have the manual and schematics on hand as a heads up.
