You have a short somewhere, you should check your alternator and make sure that it is working properly, and not draining the battery, also check your battery wires. Those are the most common issues.

Dealer says only 5 of 6 sensors on sliding door are making a connection. The sensor not working is drawing power, effectively killing my battery every 3 weeks or so.


Does your vehicle sit for 3 weeks at a time? There will always be a draw on the battery. It is called a parasitic draw. This draw comes from computers and modules within the vehicle to maintain memories. If the vehicle sits for 3 weeks or more, this small drain will deplete the battery. If the vehicle is driven daily and every 3 weeks the battery goes dead overnight, the draw will have to be high. If the door is the problem, I would suspect the battery to be dead every morning. Removing the door fuse will illiminate the door as the problem. The life expectancy of an automotive battery is 5 years. Anything older can start to cause electrical problems.

Battery drain


I would first guess the alternator, have it checked for how much power it is putting out with a meter. If it has to be replaced, it is pretty simple to do so and a cheap one can be bought from a nearby salvage yard. Check out www.car-parts.com for the nearest location of a yard that would have your alternator

I have a 95 Grand Am. We had a long and cold winter here in michigan. So my battery died. I purchased a new battery recently and car started right up. After sitting in my driveway for a few weeks, battery...


You need to run a parasitic drain test with a multimeter. Disconnect the vehicle battery positive terminal and connect the multimeter in series between the battery positive terminal and lead. the multimeter should be set to display amps. With all systems turned off, the keys out of the ignition and all doors closed, alarm off and any hood/bonnet switch depressed then after 20 minutes the amp reading should be around 0.03 or less. If you have more than 0.05 then you may have a parasitic drain, causing a n accelerated loss in battery power. In this case, using the same setup then pull fuses one by one from the fusebox until your amps drop down to the normal range. The fuse you pull which causes the range to drop to normal represents the system which is at fault.
The most common causes of parasitic drain from my experience tend to nearly always be failed back up batteries in alarm siren modules or badly wired or faulty stereos. Those are the two systems I'd pay particular attention to.
Of course it may be a simple human fault like you left your trunk/boot light or interior light on.

MR 2000 toyota would not start after sitting all winter.


the battery can be disconnected if you let it sit for more than a week. most common drain that i encounter is in the audio system. disconnect the negative battery cable and put a test light (wired light bulb) between battery post and cable end. if the light is on or even dim, start pulling fuses one at a time. if the light stays on, replace the fuse and move on. if the light goes out then you have found which circuit the draw is in.

2011 Hyundai Veracruz Limited battery keeps getting drained help


Assuming the car is still covered under warranty, I would take it to the dealer first.
If a garage works on the car, the dealer can void the warranty if something goes wrong.
The cause could be a large number of components or a short in the wiring. You have to disconnect each circuit-fuse until you find the power drain.

1995 GMC Jimmy will just cut off while driving it. Had it looked at and after sitting a few weeks at repair center..they said I needed an altinater. Then I had to replace battery. Something is still...


If something is draining the battery you have a parasitic draw on the electrical system . There are a couple ways of testing for this . GM insturment clusters can cause this problem as well as a module not powering down . Really don't think electrical wire burnt problem . The car would catch fire an burn up.
