Greetings all! Just a quick informational post for your reference. I pilfered a fuse from one of my UV-5R battery eliminators, and in the process, broke the leads off the cigarette lighter body. As they weren't the standard Red/Black pairing, I had to take the whole thing apart to make sure I had the right wires. I also used the opportunity to make up a PowerPole Battery Eliminator for base station/data use. Anyway, on to the pics!
Here's the problem child: as you can see, there's 4 different color wires inside the coiled cord, so of course, they used yellow and green. Also note the cord enters the hollow battery case at the center-line.
In order to be 100% sure I had the right terminals going to +/-, I busted another open... and found it to be completely different. Note the cord enters the hollow battery case off to one side in this version, and they've used Red/Black correctly:
And the underside of that PCB in case anybody needs it...
I hope this helps somebody, if for no other reason than a cheap way to run the UV-5R's off shore power with PowerPoles.
