Futaba Charger TX Not Lighting Up Or Charging.
I have a FUTABA Model FBC-19B(4) charger. When I plug it up to charge my Receiver battery and my Transmitter battery the RX light comes on but the TX light does not. How do I check the TX lead to make sure the TX lead doesn't have a short in it. The RX side is charging but the TX side is not.

If the charger checks out OK, the you should open the TX and check the internal wiring of the TX. If any wires from the charging jack to the battery / charging circuit are broken / open, then the charger's voltage / current is not getting to the battery, and without current flowing, the LED in the charger is not lighting up. You can use the Ohm meter part of the DVM to check for continuity of the wires and solder points.
Finally, use the volt meter to check the voltage of the battery pack and its individual cells. If you have 0v on the pack of one of the individual cells, it may be time to replace it.
