On my JR 9503, I mistakenly put a 11.1v battery in it.

Before comments: I have too many toys. I had to replace the antenna, and while waiting for the antenna, I put all items in a box.

I replace the antenna, and somehow mistakenly put a 11.1v battery in the radio.

I know I blew something as I smell it.

Suggestions on repair? I am fairly knowledgeable with passenger vehicle electronics, but just want to see what I am getting into if I attempt repairs to this radio.

I will appreciate your suggestions,

Dennis

PS: I am glad I have 2 of these radios and fortunately I have copied my settings to both. So I have not lost any data, but I am being very careful with my other radio. I don't want to lose both.

You would better to sent it to the repair shop. To risky trying to repair it yourself. If theres a fuse burnt out it still means that 12+ volts went to everything in the system. Then something drew more current than it was suppose to to burn the fuse out.

I am hoping the fuse caught the surge before the 12v got to anything else.

Smell It!!

If you only took out the fuse, and can smell something, I would say to send it in too!!
If just the fuse, you wouldn't be smelling anything...
Better safe then sorry!!

Long time ago I did the same thing. I called Horizon and the guy on the phone told me to check the fuse before I send the TX in... He walked me through it and it was simple enough that even I could do it...
open the TX carefully.. and the fuse is on the back plate... change that before you send your TX in for service...

UPDATE: The fuse is BLOWN. I replaced it.

I soon as I put the fuse in, the radio powered up. The switch is OFF. ON/OFF switch is definitely inop.

I know the smell of a burnt circuit board. After inspection it looks like the board the power switch it attached to is burnt in several areas. It's hard to believe the power was able to burn the board before the fuse blew.

Good thing, it looks like all my Heli's are there. I didn't try the radio out on any of my heli's, I didn't want to push my luck. But all functions and menus are working!

Looks like my radio is taking a ride to Horizon! Hopefully they can replace the power board, and everything will be OK.

PS: I had a printer board that almost was on fire one time. Luckily I pulled the power cord from the wall plug as soon as I saw the green smoke! My office smelled like that burning board for months.
