Yes it is necessary to jump the diode in the TX (providing there is one) if
you want to use any type of smart charger. If you did not do this, the
charger would not be able to read the voltage of the TX battery pack through
the TX charge jack. You can eliminate the need to do this need by simply
bypassing the charge jack and plugging the charger directly to the battery
pack. You may need another connector or charge cord to do this. This means
you have to disconnect the battery from the TX everytime you charge the
battery which could theoretically reduce the reliability of that connection.
The added measure of safety in doing this is that you eliminate the chance
of a short in the charger or battery wires from destroying your transmitter
due to a battery meltdown (something that has happened to several people on
this list). I'll bet dollars to donuts that those who have suffered
meltdowns due to wall-wart chargers did not have or bypassed the diode in
their TX's.
Someone else can jump in if they think it is better not to do this.
Good Luck,
Roy

Subject: [RCSE] Jumping Diodes !
Fellow pilots- Just got my new Sirius Pro Charger, and read the part about
"jumping" the diode. Their website shows nice pictures and instructions on
how to do it. So, I opened the back of my Airtronics RD 6000 to take a look.
Now I am
hesitant to stick a soldering iron in there to add the jumper wire. Is this
procedure
absolutely necessary ? If so, I'll have to decide if I can do it or one of
my
electronic
buddies. Thanks ! - JACK.
