Hi. First off, sorry if this is a redundant post. And if anyone has any pointers to similar asks in the forum, please let me know.
I have been collecting pins for a number of years, but finally have enough time to work on them beyond basics. As I am starting my troubleshooting/tech work, I am certain that I am missing tools/techniques commonly used to get things done.
My current project is fixing some lighting issues in Williams’ Indiana Jones. In the process of installing LEDs, I identified a string of GI lights (upper playfield) that aren’t working. I traced the wiring back to a jumper on the driver board, and where one of the wires goes into the connector, there is some charring, and it seems like the electrical connection is now broken. Also, the fuse for this string of lights seems intact. I am assuming there is a short somewhere in the string, and I don’t want to clean and repunch the wire, because that may blow the fuse or do worse. So a couple thoughts come to mind... If I want to drive the lights with an external voltage source, are there variable power supplies that people use to drive lights (instead of using the machine itself)? Are there “tricks” to use to trace down where the likely short in the string of lights resides? Are there toolkits that come with connectors with breakout leads so I could use alligator clips/etc.?
Once again, I feel like I am asking questions that have documented answers, or that any pinball tech could answer. Pointers would be greatly appreciated. Also, I live in the Pasadena, CA area, so if someone knows of a good tech around here that might help as well.
Thanks in advance.
