Have a Tempest playing blind. Have several repair guides to start troubleshooting....Is there a list of connectors anywhere? Just need to double check I'm checking voltages in right area...Example I need to check P900 pins 1 and 8 for + - 28v but the only p900 I see is the conn leading into HV cage and conn does not have a 1 and 8....Guessing most are written very small on the boards but wanted to double check.

Thx
 
The P900 pins are labeled 1-8, but two of the pins aren't populated. However you still go by the number of the position, not by counting pins. (And the numbers are printed on the top side of the HV board).

All of the info you should need regarding voltages is in the schematics.

If the deflection board doesn't have an LV2000 or LV6100 installed, that's the first thing you want to do, regardless. And recap the HV board, as the original caps are always bad. And reflow the solder joints on all PCB connector headers.

It's very likely you have other issues as well, but those are things you need to do anyway, and arguably should do before trying to troubleshoot any issues.

Thx...Exactly what I decided to do.
