Exclamation Just a SWAG, but I feel that oldstick might be wrong about this.

No. Unless the "Power Converter" has been replaced by really sophisticated and expensive equipment, you should test with a battery in place. The Converter tries to measure the "State of Charge" battery Voltage before choosing what output Voltage to create - and with no battery present, it is likely to misbehave, wildly "hunting" to figure out a "correct" voltage to push into the 12V power bus.

And more important - with no battery to provide RF "filtering" for the converter power output (which comes out really nasty, from the OEM Converters), the TM electronic stuff could actually be damaged. It doesn't need to be great battery, and you can get buy with just one (as long as it's 12V). But you do need to have that battery connected, or have the TV plugged in and running.
