Unhappy 94 Camray has electrical leak

I have tried to get this fixed but no one seems to be able to locate the source of the leak. My battery will die in 7 -10 days if I don't drive it. Battery is fine. The CAA battery guy used his tester on it and said I have a 2 amp leak, but no one can seem to figure out what is causing this. I have installed a moveable battery post, so that I can disconect my battery every time I park.
Any ideas ?

These situations can be frustrating because it takes time to track down. Most of the time in these situations, the radio is the cause. The radio will be defective drawing amperage when car is off. I would recommend you removing the fuse to the radio, or disconnecting the plug from the back and see if that works.

Have you sat in your car when it's dark out, when it's off, and see of anything is on? Sometimes a small thing like the glovebox light if so equipped, will drain a battery if it does not shut off.

Yes, I've checked whats on

I have turned the radio off, but maybe that won't stop the leak? If that is the source. I've checked the light in the trunk, it turns off. I think the only thing that continues to run is the clock.

Two amps is a pretty good draw. Way more than the clock or radio when the ignition is off. Since you checked the trunk light, check the glove box light as HotinOKC suggested, and also check the under the hood light.
Have you added any aftermarket accessories such as an amplifier?
If you had access to an amp meter, you could start pulling fuses, one at a time, until the amperage dropped, and then could narrow your search.

Question 92 Lexus Coup Elect Drain

I'm having the same problem with my Lexus. Sears DieHard battery (#30023 "WeatherHandler") test OK but has drain?? (didn't say how much) I bought a charger & will charge it to 100% but it will be down to 45% in 4 days if don't run it. When I drive it to airport (20min) and get back 4 days later the battery will be dead. I've already pulled C/Bs for radio & trunk CD player, pulled bulbs from trunk, hood & glove compartment. Fluid in battery looks fine.

I'm pretty sure that I should have bought a different battery model for this car. Could that be my problem.. wrong size battery?

Any other ideas before I start pulling the rest of the C/Bs one at a time? Do you connect the amp meter to the battery post while pulling breakers? Can I use the battery charger to check for elect leak? It shows % charged & battery voltage (12 volts today & 40%).

To connect the amp meter disconnect the positive cable from the battery then connect the meter between the two with positive cable of the meter to the positive battery post. If you have a drain on the battery it should show the amount of amps. If it doesn't the battery may have an internal short that is not uncommon. If there is a drain on the battery start pulling fuses.

If you figure it out let me know

Same as mine, I know its the right kind of battery in mine. I took mine back to the dealer, their solution was to install a new battery. So I purchased a battery charger as well, but what works better is a moveable battery post. A friend got it from Princess Auto parts, he installed it in 2 min. You just turn the top and it disconnects the battery. A good auto theft deterrent as well.
I will have to find an amp meter and pull the fuses, but I think my mechanic already tried that.

Question Batter Drain (Continued)

I've been trouble shooting more and have this to add to my dilemma. The battery is a 3yr Die Hard installed 9/05... older than I thought. Anyway we have had this problem starting within 6 months of getting the new battery and finally bought a charger in 11/06 after having dead battery at the airport.

FYI. I haven't tried the amp meter yet but I plan to hook that up next week. I do see a small spark when I connect/disconnect the pos battery terminal with all radio & CD player fuses already pulled.

I charged the car to 100% 13.4v and then disconnected the positive terminal to test what it would be the next morning. It was down to 70% charge & 12.5v with the battery disconnected (<12hrs). We keep the car in a >40deg garage so don't think it's the cold weather drain.

This doesn't seem right to me so I will take it back to Sears to see if they will prorate the balance of the battery warrantee and replace it with the correct size & model. Could the battery discharge with just the neg terminal connected or should it be close to 100% charged?

how about one of the solar chargers they sell for keeping battery's charged ?

probably cheaper than tracking this down

something like this 50 bucks ,

Every time the battery is disconnected, you lose memories in the clock, radio pre sets, and more importantly the engine computer. To me a dollars worth of cure beats a ten cent band aid
