A diode is a safety device installed in your transmitter that only allows voltage to go one way. All Futaba transmitters have diodes built into their circuits to protect your radio. If you accidentally plug an unprotected transmitter into the wrong brand of charger, you may destroy the transmitter. If you accidentally plug a Futaba transmitter into a JR charger, for example, all that will happen is your transmitter does not get charged, no risk, no damage.

If you wish to cycle your Futaba radio's transmitter batteries, you simply need to remove your transmitter pack from your transmitter and then discharge/cycle it, and reinstall it back into your radio. You may need to utilize banana plugs to attach to the charger leads.

We do not recommend jumping the diode in your transmitter as it removes this safety feature from your radio system and also risks damaging the radio. Please also recognize that doing so voids your radio's warranty. For an alternate solution which leaves your transmitter's diode protection in place, please consider soldering two J plugs inline instead.
