Note: See Bill's post #14(below) where he explains when and where you should see voltage readings on your TV bargman connector.
I assume you are using a multi-meter which allows you to check for:
Voltage in (Volts)
Current in (Amps/miliamps)
Resistance in (ohms)
But for the problem you are having to determine whether it's the TV or the TM,
You should be checking for DC voltage +12v on pin 3 with the voltage setting on your meter. If it has a range setting, set it higher than 12v.
Connect meter red lead to pin 3, meter black lead to ground.
***By the way, using an ohms setting to check for voltages can possibly (EDit:damage your ohmmeter).(your right Bill
) You should only use the ohms setting when you know there is no voltages present and you are checking for continuity.
