If I'm not mistaken, the diode in the entry level Futaba's was in the charge jack circuit to prevent reverse charging the Tx battery. More expensive Futaba's use a PolySwitch circuit breaker instead of the diode. I'm pretty sure that if you connect the battery to the radio with reverse polarity, there's no protection against that
Futaba's use of a standard servo plug for the Tx battery does make that very hard to do. You really have to wire the connector backwards to let out the magic smoke

delwinnikolov,
Nice to hear you have it fixed
