Now that's a one in a million occurrence!
You could have been searching for years.

Believe me, I pulled some hair before connecting the dots

A few months ago I had a slow draw going on. Once in a while the battery would go completely dead. Someone suggested looking at both doors to see if the "light switch" was fitting properly - springing back into place properly turning off the inside lights. Turns out the passenger door switch (inside jam) was bad as when I parked in the garage once in a while the passenger door switch was not operating properly. I adjusted the switch back into place and haven't had a problem since.

Well, you guys have given me several good clues to look for. Well, except Phil. I haven't polished wheels in a while

Regardless, this thing is pulling nearly 1 amp which is huge. More looking today after I get the honey do's done.

OK, I'm an idiot. I left the device to the analyzer connected to the ADL. It was what was pulling juice from the battery even though it wasn't hooked up to my laptop. DUH! I owe everyone that commented a beer and I get the stoopid award this week.

Hey, problem solved! That's what counts...

You guys are geniuses. I had some work done on mine, go it back and took it out for about a 50 mile drive. Put it in garage on a battery tender. Two days later battery tender not charging battery and battery was dead as a door nail. Since battery was over 8 years old (April of 2009) I just put a new battery in thinking problem solved. Two days later new battery dead as a door nail. I thinking oh crap. After reading these posts I found I must have bumped the courtesy light on my way out of the car. Turned off and am charging new battery. Pretty sure problem is solved. I do subscribe and appreciate the KISS principle. Thanks for reinforcing it.

Glad the problem was fixed.

Just general FYI, but many forget the courtesy circuit switches on the lights when the door is open, and there is a delay before the relay is switched off, adding complexity to the process intended.

So, just pull the courtesy fuse(s) before testing then?

Well, yeah, you could. But that courtesy fuse carries a lot of baggage, e.g., lights, door locks, etc., that confound the search to the solution.

One way to get around that is once it is determined there is excessive draw is to pull the battery panel off and measure the current at the battery while removing the fusible links, one at a time to see which one has the excessive load. Then the electrical schematics in the electrical FSM will steer ya toward isolating the culprit(s). That way if it IS courtesy-circuit related, you can evaluate it before inadvertently activating various relays when opening the door.

Hi Doug. I've been around. Haven't had much time to drive or do anything with the Vette but I still have it. I resolved to drive it a lot more this year. I have a kid who keeps me very busy, playing soccer all the tome, all over the state. I can't come to Morosso this weekend as I have a guy's trip planned for CA all next week and I'm leaving Saturday. I will be checking in periodically. Maybe we can meet up this summer.
