Question about 2005 Chevrolet Suburban

Open Question

2005 Chev. Suburban 5.3L Vehicle has a full voltage drain on battery. I have pulled every fuse & circuit breaker with a volt meter between the neg. cable & terminal with no drop in battery drain. Also unplugged ABS module under car below drivers seat. Amp meter shows full charge while vehicle is running. Have to disconnect battery every night to keep it from draining. Installed new battery to no avail. Any ideas? Thanks, Ron

dear friend-the voltage that you are measuring is battery voltage and as soon as you try to start the vehicle it will drop to 9 volt which is not enought to start.if you remove the pos,battery clamp and put a test light between the pole and the terminal and and the light lites up then there is a draw running the battery flat.

SOURCE: battery won't stay charged

You say your test light was hooked from the negative terminal of the battery to the chassis? This is correct?
If so you don't have a short you have an open circuit.
You will have a bad ground somewhere between the battery and the engine or between the the engine and the body. Trace your grounds.

Wont start the starter is working yet it won crank what can I do

Did you check power an grounds using voltage drop testing , did you check battery voltage an computer control at the starter motor relay in the under hood fuse / relay box ? Instead of guessing you need to learn how to use a DVOM - digital volt ohm meter an test ! The powertrain control module controls the starter motor operation ! Starter Voltage Drop VEHICLE RELAYS Operation Diagnosis ,If you pull the relay an jump pin's 30 & 87 the starter should crank ,test the circuit starter motor side ! Pins 85 & 86 are the control side ., Pin 85 or 86 forget which one has battery voltage with the key on . The one with out voltage is control from the engine computer ! Also if the anti theft system is active it wont start !

Voltage draw down found!
1) repaced bad battery
2) rechecked voltage draw...

Voltage draw down found!
1) repaced bad battery
2) rechecked voltage draw still showing 12 volt drain with all under hood fuses, relays, and interior fuses and relays pulled.
3) Computer was the 12 Volt drain, & had to reprogram itself.
4) gave the new battery a good long charge, reinstalled the battery into the vehicle.
5) Hooked the battery up, pulled the keys out of the ignition, close and lock all doors with auto door lock. Waited minimum of 20 min so the computer would go back into the sleep mode.
6) after 20 minute wait, rechecked the voltage draw by removing the neg battery cable from the battery, hooking volt meter + lead to battery cable end, and neg lead to battery neg post, nothing showing or zero reading.
7) Hooked the neg cable up to battery, started the truck and let the engine idle to normal run temp, then fast idled 1200-1300 rpms for 2 minutes, then drove the vehicle for 5+ miles and alternating speeds. All appears back to normal now. Alt showing 14.2 to 14.4 volts, and no other problems.
After all of the afore mentioned, my problems began with a bad battery cell, thus caused my computer to have the memory reset.Until the computer was reset, I had a 12v continious draw down! I got this info from a repair manual, that I purchase sometime ago. Thanks for your alls help........EJB

My transit van on a53 plate, is draining the battery, I have had new alternator, and battery but it is still draining battery,

Battery drains are always fun. Generally it means that something you either hooked up recently to a direct hot wire is draining the battery or there has been a wire that got hot enough to melt another wore on the system and cause a full time connection. Other than taking it to the dealer and letting them put a breakout box on your system to isolate the problem, you could put a volt meter on your battery, if there is truly a drain on the system you will see the volts slowly drop, then open your fuse box and one by one start pulling fuses until you find the one that's pulling on the battery, (you'll know this when the volts on the meter stop dropping). When you find the fuse that's pulling the volts down, you'll then be able to start tracing the circuit for that fuse and everything connected to it. It's a PIA but it's something you'll have to do, unless you want to pay dealer prices.

I have a draw on the battery on my 85 Toyota pickup it kills a fully charged battery in about 2 hours... Ive put a volt tester between the disconnected positive battery cable and the positive battery post...

Go to You Tube Video & see how to do a parasitic CURRENT
drain test

What you have done so far with a test light & volt meter is basically
doing nothing

You need an amp meter & a wiring diagram,then pull fuses one
at a time, to get to the circuit that causes the drain,then use the
prints to test that circuit for voltage drops

Battery drains while sitting

Hi Anonymous, perform the following tests:
1. Fill acid type batteries to proper levels.
2. Charge battery overnight at 1-2 amps you need 12.5 volts or better after charging.
3. Hook up battery positive cable, then with your multimeter on the milliamp scale connect one lead to the negative battery post and the other lead to the ground cable. Meter should read 3 milliamps or less, 10 milliamps with a radio, 15 milliamps with radio and CB. If your meter reads higher you need to isolate the circuit by pulling fuses and circuit breakers one at a time and observe meter for drop in aprerage then get out your test light and track down the short in that circuit.
3. Make sure all connections are clean and tight especially the negative cable at "BOTH" ends.
4. Hook up volt meter to battery and start engine, if meter falls below 9.5 v while cranking replace battery.
5. With engine running at 3600 RPM battery should read 14.3-14.7 volts if not continue tests.
6. Unplug voltage regulator from alternator at crankcase by front of primary cover.
7. To test voltage regulator go to:
8. With ohm meter, one lead grounded, touch alternator pin meter should read infinity, if not replace stator.
9. With ohm meter, both leads touching alternator pins meter should read 0.1 to 0.2 ohms on 1989 and later models. 0.2 to 0.4 ohms 1988 and earlier models, if not replace stator.
10. With volt meter set on AC scale, both leads touching alternator pins meter should read
16 to 20 volts AC for every 1000 RPM'S 1989 and later and 19 to 26 volts AC for every 1000 RPMS. If not replace rotor.

96 tercel keeps draining the battery. Alt. is new and fuse and breakers are good

Your going to need a volt/ohm meter for testing this prob. You need to put the meter on amperage mode and turn off all devices in car and close all doors and make sure key is off! Disconnect the negative battery cable and use the meter to hook from the battery negative cable to the other end of the cable, basically the meter is completing the circuit. Once you turn the meter on the vehicle will have to power down cause your meter connection will have woke up several modules, wait bout 5 min with the meter on, if the meter is 10 ohm scale a good reading should be around 0.025 to 0.001, if it's anything higher then pull fuses 1 by 1 until the draw falls into proper range, that will help you narrow down what circuit the draw is related to. Quick check, make sure the trunk light and or glove box lights are actually turning off, most common prob for current draw..

For a battery to go dead on you like that there must be something draining the battery while the vehicle is switched off. It could be something like a trunk light which is not switching off or a short across some circuit that does not show up on any light. The first and easiest test is to disconnect the battery negative cable whenever you park the vehicle overnight etc. and see if the battery still runs down.
As a more positive step and if this does not affect the alarm, disconnect the positive lead from the battery and wire a bulb like a tail light bulb, between the terminal and the removed lead. The bulb should light up. Make sure that everything on the vehicle is switched off, the bulb should still be lit. Remove and replace the fuses one by one until the bulb goes out. That is the circuit that is running your battery flat. Check all the components on that circuit until you get the light to stay out and your problem should be fixed.
Check your charging system. With the engine running at about 2000 rpm, a volt meter across the battery terminals should read around 14 to 14.5 volts and drop to about 13.8 volts with the engine at idle. If this does not happen, the charging system may be defective. Even with lights on the voltage should climb, but will drop lower at idle.

Checked alt passed, new 175 amp,getting 11.5 volts when running until the battery goes dead

A 12 volt battery has 6 cells, @ 2.2 volts each = 13.2 volts Static (theory)

Now you need a min of 12.5 volts, to conduct any testing,or you
charge the battery first

When the engine is running,alternator turning, you get 13.6 approx to
14.4 approx. --output voltage

You can not charge a battery without a higher voltage than what you have.

When a battery sits over night fully charged,you should have 12.62 to say
12.67 volts

So you still got problems to work out.
You can pull out fuses untill you find the circuit,that has the issues
and possibly something on that circuit, is not timing out

If you have an Amp Meter, you can put it in series,in either battery cable
and start pulling fuses untill you get under 35 milliamps. You will
have 25 to 50 milli amp to power the clock,computer modules etc.

The battery keeps going dead in my 03 z71, only thing out of place is i cannot shut off the headlights manually anymore,it's stuck in auto. Alternato is fine and so is the battery, drains iin about 7...

Well if lights are not staying on then you have a draw of power somewhere. Easy way to find out is volt meter. You take off negative cable and put one end of meter to battery post and other to wire dont let the wire touch post or anyother metal of vehicle. Then go through your fuse box and pull fuse's one at a time until you see voltage on meter drop. Meter should should a (-)negative voltage at start and get smaller when right fuse is pulled take notes and pull all one at a time and replace back in orginal spot. If you find one that really lowers the negative voltage draw on meter good chance you found where problem is. Id start by checking all interior lights first, including glovebox.

Something is draining the battery

You have a draw and a draw pulling more than a couple hundred milliamps.This will drain the battery in an objectionably short amount of time.. All the things you mentioned and more can cause this draw. The best diagnostic step towards isolating your draw is with meter that reads Volts DC or better yet a test light.(I think) ..disconnect B+ positive battery cable. Install meter or lamp in series with disconnected cable and battery post. You do have some smal draws like computer memories,clocks etc which will show a low amount of voltage hence a very dim test light. If you are drawing heavy ,obviously the meter will show a full blown 12 volts and the lamp bulb will be very bright. Remove fuses,unplug relays,dis-connect devices while watching the voltage or lamp.You should begin to isolate offending item once the circuit has been detected, Generally pulling all fuses individually will tell you at least which circuit is pulling the amps.
