That shouldn't do it. I wouldn't expect an issue unless the car had been left plugged in for 2-4 weeks, not 2 days. There's something wrong.Staque wrote:I'm guessing, after searching the forum for "12V", that it was the fact that I left it plugged into the EVSE for 2 days.
Any thread where people mention a problem leaving it plugged in, the phrase "for more than a day" is used.
What is the 12V load when the EVSE is plugged in? I must be close to 1A? (I don't have an ammeter.)

Being in 'On' does the same thing as being 'in Ready" (it's like being in 'ignition mode' on an ICE, but not starting the engine..) the computer and everything else are still sitting there running... the blue light was on because the DC to DC converter was recharging the 12v battery so it didn't die.lpickup wrote:Well now I have to share a story.DanBaldwin wrote:Out of curiosity I checked my 2012 SL, and it doesn't run the dc/dc converter in accessory mode, or in on mode, only in ready mode.
I was at a hockey game about a month ago. I had the car in ON mode playing music as we tailgated. I thought I turned it off when we left, but maybe I didn't. My wife left her purse (with a fob in it) in the trunk (BTW, I am not condoning this practice! I'm against it!).
When we came out a couple hours later, I notice the car's headlights and taillights are on (I keep the lights on AUTO so obviously when it got dark while we were inside, the lights came on), the dash is on (I'm pretty sure it was in ON though and not READY), and the third blue dash LED is lit (I'd never seen that one lit before so I looked up in the manual what that meant, and it meant the 12V battery was charging).
I suppose it is possible that my recollection is not good, but I'm pretty sure the car was not in READY, but rather just ON.
