JR 10X charging
Hi Danny,
Several months ago I read a suggested technique for plugging in Tx chargers which supposedly would prevent the possibility of blowing the charge circuit fuse. The suggestion was to turn the Tx power "on" before plugging the charger into the Tx, then turn the Tx power "off" to allow charging. Since I had previously blown the fuse in my 652, I decided to try the technique.
I have noticed that when I follow this procedure with my 421 and 652, the indicator light on the JR wall charger won't light up until I turn the Tx power "off". That makes sense to me; however, when I follow the same procedure with my 10X Tx, the JR wall charger indicator light comes on as soon as I plug the jack into the TX (with the Tx power switch "on").
I am puzzled---what's going on? Is this procedure good or bad, and why the difference?
Thanks for your time.

JR 10X charging
Until you get an official answer from Danny, I'll take a stab at it. The 10X battery pack actually has some sort of little circuit board in it if I'm not mistaken. Not sure what kind of magic of the board performs, but it may have something to do with what you are describing_bob

RE: JR 10X charging
That procedure wouldn't really help reduce the risk of the blowing a fuse. The 10X has a separate charge circuit, which allows it to be charged while the system is on. It wasn't designed for that purpose, but rather designed that way to have charge protection when the battery is removed from the system, and this is a side effect so to speak. The board Bob speaks of is the charge circuit protection for the battery to protect it from damage. Generally when a fuse is blown, either the insulator ring on the charge plug from the charger is worn allowing the center pin to contact the outer plug and causing a short, too high of a charge rate is used with aftermarket chargers, or there is some other reverse polarity or short happening.

RE: JR 10X charging
Danny,
Do I take it from your comments that it is inadvisable to charge the PCM10X Tx using a fast charger. (The unit which I had in mind was a Schulze 6-330d Chameleon with a sophisticate peak detection circuit to avoid overcooking the batteries.)

RE: JR 10X charging
Fast charging is fine with a good peak charger, I would recommend staying at or under 1 amp for the charge rate to reduce the risk of blowing the fuse on the charge circuit board in the battery.
