RE: Is my JR screwed?
I don't know about the original post but I have a XF622 and just did the same thing. This is my second time in 6 years. It is very easy to do, plug the BATTERY in to the radio backwards when using non JR(less expensive but the same quality, yeah I know not if I keep blowing radios) batteries. Anyway, the fuse never is fast enough to catch the problem, so all you guys can forget about the fuse being blown. I had to send it off last time.
But the point is, what part needs to be changed?? Any help from the extech guy would be appreciated. I can change the part myself if someone can point it out.
Also , anyone suggest a way to stop this, a diode or something soldered into the circuit?
Thanks for any help
