Well I did the ignition switch test on Javier's NH and it has .9 Ohms with the key on. So that would mean that the NH draws 15 Amps, which if I remember correctly from the thread about heated gear, should be about right. It looks like the lead acid battery that was in the GS is holding a charge because the battery tender topped it off in just a couple of minutes and it has been sitting on a shelf for almost 2 weeks now. I'll give that a try and see what its voltage drop is with the key on.
