MacGyver'ing an A4 Charger? Help?

Been restoring, tuning, and custom moding some old guns lately. Just finished cleaning/regreasing this Cobra A4 Fly and now onto charging... found the charger with the plug ripped off

From the pic, you can see there are two wires (blue & red) down in there. I'd like to solder a plug back onto the ends - does anyone have a quickie schematic of how to do this or what it looks like? Where can I get a spare plug?

If that fails, is there a way to hardwire it onto the board to charge it temporarily?

Or could I possibly modify an LCD charger?

What you're after is a size H coaxial DC power plug. Radio Shack carries them, or you can find them online. The important thing to remember with the Angel charger is that the OUTSIDE sleeve is positive. This is backwards from most configurations, so make sure you get it right.

The man!

I appreciate it. I could not for the life of me find this solution via Google searching.

Outside sleeve is positive? Will this play into how I solder the two wires in?

It will. When you unscrew the connector you will see that there are two solder points, one on the outside and one in the center. The center point is for the inside sleeve, the outside point is for the outside sleeve. I might be able to dig out my charger and take a pic if that helps.

Gotcha. Well now I just need to figure out which of the two wires is positive - red or blue?

On my charger, red is positive, blue is ground. Here is a pic of the assembly:
