Pin 5 (orange wire) coming off the bottom connector (P900) of the HV cage is your B+ wire. It's easier to test it where it connects to the neckboard, though. Stick your red lead on that and your black lead on the monitor frame. You should have close to +180vdc. If you need to adjust it (if it's below 172 or higher than 188), you do so by turning a pot on the HV board. There is a hole in the top of the HV cage to stick a long screwdriver or adjustment tool down there, but I recommend removing the cage mesh for easier access. If you hit the wrong thing with a srewdriver tip, you'll short something out and maybe get zapped, too....

Well, I thought I had HV, but measuring the B+ at the following locations only gives me between 2 and 3V (fluctuating).
So I guess it's back to the flowchart for me. Next step would be to turn up the brightness and contrast on the HV PCB and check for a dot. Although I know there is not +/- 28VDC on pins 1/8 of P900 already. I am thinking I will just install the cap kit when I get it and test again. Chances are if I were to find a defective part I would install all the replacements in the upgrade anyway, so I might as well save the trouble-shooting time now.
And thanks again for the help. There is so much information to absorb.

Did you also order a LV6100 or LV2000 ?

Yeah, I sent an e-mail to Mark Spaeth but haven't heard back yet, and haven't had any luck hearing back from him in the past. If I don't hear from him soon, I will go ahead with the LV2000 (presuming I can find that one).

Yeah, I've been trying to contact Mark about an issue with the third SW/ESB kit I installed (doesn't work) but no luck. The irritating thing it that he _is_ posting on the KLOV forum (and yes I PMed him there too)......
And here's a good tip for finding the LV2000:
