Odd thing just happened to me. S/O and I went to the local Cracker Barrel for dinner. Just as we get there to park, she pushed in the cig. lighter, but it didn't pop out before I parked and shut the ignition off. 2 hours later, the battery was stone dead - needed a jump to get going.

It ran fine afterwards, the DIC showed 13.7 - 14.1 volts going in to the battery.

This happened once before when I left my cell phone charger in the cig lighter overnight.

Is this SOP for the lighter to stay "hot" even with the ignition off?

For the cell phone charger with the cell phone hooked up all night, might drain a battery (maybe:hmm: ). Just the charger, without the cell phone, shouldn't be a problem. As far as the lighter is concerned, those things should pop up when they are hot. Shouldn't be draining a battery. Pull the assembly out and look for a short in it. Maybe the assembly itself is shorting out.

What's an S/O? Probably something obvious, but apparently I am not thinking.

Nevermind, significant other, figured it out.

Melting the insulation would be the least of my worries with an open flame under the hood.

"and three cups of heavily sugared Maxwell House" - that's a good one.

Those pics look like you had yourself a little workout.
