Williams Jokerz - Rebuilding Level 0
Underside parts
The underside parts portion of the rebuild mainly consists of checking and replacing worn parts, and lots of cleaning. For this project, I put a small number on each component (with a fine-tip Sharpie pen) and a matching number on the wood where the component was mounted. Then I removed the component and moved on to the next one. This made reinstallation of the wiring harness and the attached parts much easier.
Rather than go into excruciating detail, I'll present here some photos of the playfield underside for those looking for a known-working reference. Scroll down the page for a few close-up shots of interesting details.

rebuilt at this point, remember.
