I have one old JR radio. I cut my old charger up to hook up to my new quick charger and I don't know what is positive, negative and neutral for a JR connector. I haveorange, red and brown wires. If anyone can help me out I would appreciate it.

I can't believe no one has jumped in to help you.

 orange= signal
 red= positive ++
 brown= negative

Hi!
Orange =puls
Brown= -
Red= +
On all JR and Spektrum transmitters the center pin is minus..!

Thanks for the quick response guys!!

If you are talking about the charging plug for any JR tx (the plug you plug into the tx with the Tx side of your JR wall chargers) then the centerpin is negative. The negative lead from your charger must be attached to the center pin of this plug when used in JR Txs.

The is opposite of all others except possibly Spectrum. That is why when using another brand wall charger the tx side (Tx side only) of that charger musthave the polarity reversed.
