I accidently plugged my DX7 into an Eflite battery charger and it is dead as a doornail.

What have I done?

Thanks,

If you're Lucky, it might have blown the fuse in the Tx.

I'm sure it's the fuse I've done it more than once easy fix. Pull the back off then then the board the fuse is right there. Anyplace should have a replacement.

The fuse is a fast acting 3A. 5x20mm.

Glade you got it fixed.

This is a hair off topic. But thought I'd mention it, just in case someone runs across this post. And the fuse does not fix there's. Then they will know to get a magnifying glass and inspect the traces around the fuse.

I bought a used JR xp6102 to sim with, but it would not sim the D.S.C port on the back was none working. Also it would not charge the TX pack through the charge jack on the side.

So I opened the radio up, and right above the fuse there was a blown trace, on the circuit board. Some one had plugged the wrong charger in the jack and blown the fuse and so they replaced the fuse and the TX worked, just could not charge or use the port. But I could not solder the trace, so I just jumped it with a wire from point a to b. Now everything works good.

For those that may not know.
Traces run all over the mainboards, and connects everything together. They have a green coating, but underneath the coating they are copper.

Just thought I'd add this might help someone to fix their dead tx.
