AHA! Verrrrry Interesting!
Following a wg4900 troubleshooting flowchart, I tested the voltage output by the chassis resistor, R503. It should read +130VDC. Bad news is that it does not, coming in at between +160VDC and +168VDC. Good news is I am one step closer to finding the problem. Next I need to examine a jumper wire and some traces, but I need to remove the chassis for that. I will let it sit over night (baby is asleep so best not discharge now) and take a look-see tomorrow.
Also, anyone have a Radio Shack Multimeter #22-168?
I cannot find my disk with the logging software and need a friendly download.

The software is available on RadioShacks Web page www.radioshack.com. My problem is getting it to record and print beyond screen 1. Any suggestions?
No, I am afraid I ended up not needing it for my tests so I have not used it in depth. You might try google groups / usenet group sci.electronics.repair
Good luck
