When you turn the key to off and get out of the car and walk away, you are confident that nothing is running and hence sucking the power or juice out of the battery. In your case that is wrong, something is continuing to run so when you come back the battery's power to restart the thing has gone away.

As you have not a clue, you need to pay someone to track that thing down and turn it off permanently so it does not draw the battery down when the engine is not running. When the engine is running, the alternator puts out plenty of power to charge the battery and run all the doodads.

Common doodads which continue to run even when you think they are off and cause this problem are remote door locks, light bulbs which should be off, security systems, any aftermarket toy which was installed by a dunderhead or brother in law.

Good Luck!

Engine will not start

It sounds like you have a parasitic draw on your battery, without wiring diagrams, and a good understanding of electrical systems andsub systems, finding and fixing the parasitic draw is going to be impossible. You may be substantially better in the long run taking your vehicle to a shop, and having them diagnose the cause of your parasitic draw.

Truck keeps dying, dont know what else to do?

12.6VDC is a good output from a vehicle battery. The measurement of 8.8Volts is not drawing anything, it is Voltage not can draw current in Amps or Watts only. Check the Amperage draw of your Amplifier to see what it draws and compare that number to the number of Amp Hours written on the battery. Yes, it may be what is draining the battery, like leaving your headlights on overnight! Do the math! Drawing the battery down to a very low Amperage could damage the cells in it, that's why golf carts use what is known as Low Dwell batteries that can discharge way down without damage. Have it tested or test it yourself with a relative gravity tester available at your local auto parts store. Read the instructions will tell you how bad the battery is damaged and if you need a new one. Have fun learning stuff like I do...

10 amp draw draining battery overnight on 99 tahoe

I have done this before, put about a 10 amp charger on the battery. Pull the courtesy light fuse first. Look at the battery charger, it is probably charging several amps, pull one fuse at a time. When the charging amps drops down you found the fuse the controls the problem. I had a car several years ago that someone pulled the seat belt all the way out, somehow it was pulling a load and draining the battery overnight.

Need the diagram on the fuse block for a 1997 chevy tahoe

You say (it all began when), please explain what happen > you were driving along and all of a sudden ......your turn !!!. i have a couple questions >> You do realize that the key has to be turned to the "on" position to excite fuse block wiring and unless you had a wiring harness short and cooked the wiring or have disconnected wiring , common sense says it's not the wiring, as for the fuse box & block , simply google "1997 chevy tahoe/wire harness & you can probably find info. on (you tube) searching the same way !!

Since alot of people don't have all kinds of special tools, This is a way you can narrow it down and then go from there. Make sure all lights and power is turned off in the vehicle including the light under the hood if there is one.. disconnect the negative battery cable off the battery. take a test light and connect the aligator clip part of the test light to the part of the cable that connects to the battery. Then take the "pointy" part of the test light and touch it to the negative battery terminal. if it lights up, that means you have a draw. the brighter the light the bigger the draw is. Now keep in mind that if you have a clock or delayed interior lights it will show a draw. If you do have a pretty bright light and want to see the area that the draw is coming from begin by taking one fuse out at a time. If the light goes out or at least dims down alot, then you now know which circuit the draw is coming from. Now from there once you find which fuse it is then comes the task of finding out what that fuse covers and you can work on it from there. At this point you will have an idea of the area that is pulling power from your battery and may need to get a wiring diagram to locate where the draw is coming from. Worst case would be to pull that fuse out everytime you stop the car so it doesn't drain the battery while sitting until you can make the repair. I hope you were able to understand as sometimes I have a hard time explaining things. I hope this helps you narrow down your problem and good luck.

My Battery keeps running down, I've replaced the Battery in July 2010, can it be a battery cable & how can I tell.

Try disconnecting the battery and let the car sit for a while, re-connect to see if that makes a differance. If the battery power is ok you have a problem with a draw on the system or a bad alternator.

I have a draw on my battery that read .4 amps when the vehicle was off. If the car sat overnight, it wouldnt start unless I had disconnected the negative cable from the battery, and reconnected it in the...

As a rule, .1 Amps or .2 Amps max is acceptable for the car being off.

Remember that batteries last only 3 years on average, which might explain why you had to jump the car occasionally.

I think that it was clever of you to pull fuses one by one until the multimeter read lower reading.

Wiring harnesses can look like spaghetti so if the car has a short in the system, maybe taking the vehicle to an auto electric shop would aid in diagnosing the problem if the owner has trouble finding the source of the excessive draw.

Good luck on this repair.

2005 checy tahoe battery keeps dieing every 2 - 3 days replaced battery and alternator seems fine any ideas? just replaced heated mirrors but they are disconnected now and still same problem.

There is a way you can isolate the draw with a 12 volt test light. If you have one, or can get one (about $5) get back to me, I'll explain. Takes a little time, but at least will narrow the circuit down.

LC 97 keeps losing power after about about 3 hour of

Drive over to Autozone or Oreillys and have them check the charging system while it is running. You also need to check for the "draw" of power used by the car. They may not have the gauges for that portion of the test.
One item that is silent and draws a lot of power is the rear window defroster. I don't know offhand if it is a dedicated fuse or if there are several items on the same fuse. You could try pulling the fuse for the rear window defroster.
Your air suspension can draw lots of power if the air compressor keeps running.

If you are running down a fully charged battery and all the power of an alternator, something is either glowing, or a fusible link is blown and the charge is not getting to the battery.
