Mike, can I safely remove the two connectors (J19 and J20) from the PCB board before sliding the board out? It seems last time I tried removing those connectors, they felt like they were on there pretty tight. I'll take the pics tonight when I get home. :)

Mike A:
anything that plugs in can be unplugged.

Good morning all, Well, last night I took a reading of all the "test point" voltages on the ARII board. Here is the first sign of where the voltages stop. From the board I'm missing the 10.3 VDC. The good news is that the other 5 voltages are good. The 36 VAC, +22VDC (Actual 24.6), -22VDC (Actual -24.5), 12VDC and -5VDC, all good! See pic below "ARII Voltages from board". What's strange, is that I'm missing a lot more voltages from the plug connectors on the board. Does that make any sense? There are no voltages from the P7 connector and no voltages from the P10 connector. The only voltage I'm getting is from connector P9 36VAC (Actual 36.5). See pic below "ARII Voltages from connectors". I'll have to look back on the schematic to see where those connector voltages are coming from. What do you think?

I didn't have a chance to check any test point voltages on the PCB board but I did take a few pics of the board for Mike. I forgot to take a pic of the back of the PCB board for you. I'll do that tonight as well as check all the test point voltages. I did notice that there was a jumper wire soldered across a short length of circuity on the back side. Looks like there may have been problems in the past with the board. If I hold the board up to the light, all looks pretty good except for that one spot they bypassed with the jumper. Check out all the pics below. I'll report back tomorrow morning with additional readings. :)

This pic shows the voltages from the board.
