Troubleshooting 101 - Logic - In Circuit...

The circuit boards do not have a silk screened layout on them. So it is hunt-n-peck to find what you need.
The schematics I have with the console are like the dead sea scrolls... deciphering them is taking quite some time. I scanned the really illegible ones and blew them up. Since this is my console I marked up the circuit boards with my notes, etc...

Created this to help me find my way around the IO Module.

My friend from work is an electronics person. He loaned me his ESR meter. I checked all the caps and most were fine. I replaced any bad ones that were off the scale. I did not know that much about ESR and I am glad now that I do. It even works in circuit. His was a kit he got at: ESR Kit
