You are correct, of course. I just went down and ohm'd out a Chargepoint station. It reads 150 ohms, and goes up to 480 ohms when the release button is pressed just like you said in your first email. This is the same as the one I just bought, so I'll stop thinking about this stuff now. :-)
Annoying though, that the Open EVSE wiki site is just flat out incorrect on this. You'd think they would know how it worked :confused: david. >________________________________ > From: Rush Dougherty <[email protected]> >To: 'David Ladd' <[email protected]>; 'Electric Vehicle Discussion List' ><[email protected]> >Sent: Wednesday, May 1, 2013 11:56 AM >Subject: RE: [EVDL] J1772 proximity stuff > > >I think another part of the confusion is in the link that you provided in >your first email.
