Hi Jerry, Here's the spec: http://en.wikipedia.org/wiki/SAE_J1772
That tells you what size resistors to use. -corbin On Mar 23, 2013, at 5:36 PM, jerry freedomev <[email protected]> wrote: > > Hi Corbin and All, > > I rather like flipping switches so > the problems mentioned are not much for me to handle.
