I don't Have a volt meter and I don't wish to buy a ready made adapter when I have one here I can make.
Basicly I am too cheap....

That reminds me of a story of how I just recently tried to build my own version of the jersey modelers
gas can.....wound up costing $48.00 anyways and my gas (not nitro) plug somehow is all chewed up
looking and leaking.

I was just hoaping someone knew off the top of there head.

Sorry, I have A.D.D.
