het bob has two kits to rebuild a WM power supply, need recommendation on which one to get. all my voltages are low . -3.5 +4.2 +11.5

1. test all 3 BR's
2. verify no burnt headers and or connectors
3. order repair kit with appropriate parts as needed from testing above
The other option is to send it off to Dave (Dockert) or myself to be rebuilt.

do one of you guys have the wiring diagram for defender. just got my coin door and need to wire it up.
Ken (yellowdog) and I have a running contest for the most hosed up Williams power supply that we can bring back to life.
You can find most of the drawing sets out on arcarc.xmission.com. The Williams games are mostly in the Williams folder.
I just got a box of PS boards that look like they were the leftovers from an "if you give an infinite number of monkeys soldering irons" board repair experiment. I'll try to remember to post some before pictures.

still havin a power problem, by the time 5volts gets to the chips its 4.5 volts. this is how i replaced the 18000 uf cap, i used the exsisiting leads and some copper wire and solder them together.is this how the pros do it?
No, the pros go to Ed at Great Plains Electronics and buy the correct cap.![]()
Even though it is a radial cap rather than an axial, you should mount it horizontally, secure it with a cable tie and attach the wires to the original holes. It will be less likely to get shorted horizontally and therefore less likely to damage anything or itself if a short occurs.
From the picture, it looks like you soldered it to the test points rather than the original holes. This is a bad practice. You should use the original holes.
Or as Dave said, go to www.greatplainselectronics .com and order a CEA-18000uF-25V-RMD 18,000mfd axial lead capacitor (link).
