Re: FT-817 almost powers up

b,
Is the VOM reading with the power connector plugged into the FT817.
If you do then I would think the connector has lost it's connection to the FT817 ground/neg supply connection.? If not in the FT817 then I would be concerned if the cable connections are reversed and the fT817 has another path to ground.

Hello Bill
I do not have a circuit (schematic) for the 817 here but I do know that the much earlier FT290 and FT690 had a reverse polarity diode in the negative pole of the DC power connector.
If the FT817 is similar, I would investigate the health of that, or any other, reverse polarity protection circuit / device.
Hope this helps
