2000 ford excursion battery draw

I have a battery draw that seems to becoming from blower circuit. The 50 amp fuse in the underhood box stops the draw. The fuse is 103 the battery distribution box. I have found that the fan circiut will work without the key and sometimes want turn off even when in the off position. I have to turn the key on and then off again for the fan to die. The relay under the hood has roughly 6.8 volts on terminal 85. So I guess my guestion is where does that terminal get its power? From a bcm? Need a diagram?

I have a 2002 dodge caravan and nothing thats powered from the ignition such as radio, wipers, turns, blower etc, is working, also the battery is being drained within a day


First, remove the battery - charge it fully, then load test it. If it tests good. Set the battery back in the battery compartment and connect the positive cable. Then run a test light (you can get a cheap one at harbor freight tools) between the negative battery terminal from the car to the negative terminal on the battery (basically complete the circuit with the test light in the middle). If you have a big current draw, the test light will light. If the test light lights up, leave it connected and go to the fuse box and start from the top and remove and install one fuse at a time. Do this until the test light goes out. When the test light goes out, you'll know what circuit your problem is on.

Go here http://www.bbbind.com/free_tsb.html and look up the wiring diagram. then put the fuse back in and start removing components on that circuit (for example, if the radio is on the same circuit just go down the list of items connected to that circuit and disconnect and reconnect one at a time until the test light goes back off), when it goes off, you have found your source of current draw.

If you start this process and the test light does not light during the first step, you will need a DC Amp Clamp meter to read the smaller current draw (sears has a AMP CLAMP METER that does DC AMPS for around $50). In this case, you would connect both battery terminals (connect positive first), then use the AMP CLAMP on the DC AMP setting to read the current draw and repeat the same process as mentioned above.

Please reply if you have any further questions.

Hope this helps!

Does anyone have any suggestions regarding how to diagnose no power to front blower motor in a 2006 Ford Freestar mini van.


You also have the front blower motor speed controller and the electronic automatic temperature control (EATC) module to check.

Hook up battery backwards now can't start did I blow a fuse


Could not find a main fuse in the diagrams I looked at. I would take a test light and go through the underhood fuse blocks and see if they are blown.

Underhood fusebox fuse #13 50 amp what is it for


The large MAXI fuses in the engine compartment fuse block are the MAIN fuses. They supply voltage to several other fuses or circuits.

MAXI Fuse #13 in your 1996 Ford Ranger is supposed to be a 30 Amp fuse (not a 50 Amp) according to the power distribution diagrams as well as the fuse block detail diagram. This fuse supplies voltage to the Powertrain Control Module (PCM) power relay and to the oxygen sensor heater circuits.

Please note that it is NORMAL for this fuse to cause a draw on the battery during vehicle operation and also after engine shut down. The OBD-2 oxygen sensor heater circuit monitors run after engine shut down and key off. This can take up to 45 minutes to complete. After the O2 heater monitor has run, the PCM will go into sleep mode.

When the PCM goes into sleep mode, the battery draw from this fuse will be reduced greatly. If you are performing "ignition-off-draw" tests trying to figure out why the battery keeps going dead, it is best to use an ammeter that has a 1 or 2 amp scale. You should set-up for the test using a shunt bar. Wait for 45 minutes to an hour for all of the computer systems in the vehicle to go into sleep mode, then open the shunt. Your computer memory, radio pre-sets, clock, etc. will continue to draw without ever shutting completely off. Any draw under 300 Milliamps is considered "acceptable". It is my experience that most vehicles have an ignition-off-draw of somewhere near 150 Milliamps.

The underhood fuse box diagram can be found on page 314 in the 1996 Ford Ranger Owner's Manual.

I have a draw from my battery how can I find it? I have put a test light in between the neg. post and the cable and the light stays on.I have pull all the fuses one at a time and the light dose not go...


Could be a ground problem; I send you a drain test to check it, you will need a digital volt and ohm meter to perform a battery draw test.

WARNING: Do not attempt this test on a lead-acid battery that has recently been recharged. Explosive gases may cause personal injury. Failure to follow these instructions may result in personal injury.

CAUTION: To prevent damage to the meter, do not crank the engine or operate accessories that draw more than 10A.

NOTE: No factory-equipped vehicle should have more than a 50 mA (0.050 amp) draw.

Check for current drains on the battery in excess of 50 milliamps (0.050 amp) with all the electrical accessories off and the vehicle at rest for at least 40 minutes . Current drains can be tested with the following procedure:

NOTE:
Many electronic modules draw 10 mA (0.010 amp) or more continuously.
Use an in-line ammeter between the negative battery post and its respective cable.

Typically, a drain of approximately one amp can be attributed to an engine compartment lamp, glove compartment lamp, or interior lamp staying on continually. Other component failures or wiring shorts may be located by selectively pulling fuses to pinpoint the location of the current drain. When the current drain is found, the meter reading will fall to an acceptable level. If the drain is still not located after checking all the fuses, it may be due to the generator.

To accurately test the drain on a battery, an in-line digital ammeter must be used. Use of a test lamp or voltmeter is not an accurate method due to the number of electronic modules.

When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) relearns its fuel trim. The vehicle may need to be driven to relearn the strategy.

Make sure the junction box(es)/fuse panel(s) is accessible without turning on interior or underhood lights. Drive the vehicle at least 5 minutes and over 48 km/h (30 mph) to turn on and activate the vehicle systems.
Allow the vehicle to sit with the key OFF for at least 40 minutes to allow modules to time out/power down.

Connect a fused jumper wire between the negative battery cable and the negative battery post to prevent modules from resetting and to catch capacitive drains.
Disconnect the negative battery cable from the negative battery post without breaking the connection of the jumper wire.

NOTE: It is very important that continuity is not broken between the negative battery post and the negative battery cable when connecting the meter. If this happens, the entire procedure must be repeated. Connect the tester between the negative battery cable and the post. The meter must be capable of reading milliamps and should have a 10 amp capability.

NOTE:
If the meter settings need to be switched or the test leads need to be moved to another jack, the jumper wire must be reinstalled to avoid breaking continuity.
Amperage draw will vary from vehicle to vehicle depending on the equipment package. Compare to a similar vehicle for reference.
No factory-equipped vehicle should have more than a 50 mA (0.050 amp) draw.

Remove the jumper wire. If the draw is found to be excessive, remove fuses from the central junction box one at a time and note the current drop. Do not reinstall the fuses until you are finished testing. To properly isolate each of the circuits, all of the fuses may need to be removed and install one fuse, note the amperage draw, then remove the fuse and install the next fuse, etc.

If the current draw is still excessive, remove the fuses from the battery junction box (BJB) one at a time and note the current drop. Do not reinstall the fuses until you have finished testing. To properly isolate each of the circuits, all of the fuses may need to be removed. After removal of all of the fuses, install one fuse, note the amperage draw, then remove the fuse and install the next fuse until each circuit has been tested. When the current level drops to an acceptable level after removing a fuse, the circuit containing the excessive draw has been located.

Check the wiring schematic in the wiring diagram for any circuits that run from the battery without passing through the junction boxes. This could find in the Service Manual or Haynes books. If the current draw is still excessive, disconnect these circuits until the draw is found. Also disconnect the generator electrical connections if the draw can not be located. The generator may be internally shorted, causing the current drain.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Significant battery draw on my 2007 Honda Odyssey until I remove the fuse labeled "Back Up, ACC". 40A square type fuse. what circuit does this fuse protect?


Fuse #15 "BACK UP/ACC" (40 Amp) in the Underhood Fuse/Relay Box
protects the circuits leading to Fuse #7 "BACKUP" (7.5 Amp) in the Underhood
Fuse/Relay Box and also fuses (#5 "RADIO" (10 Amp), #6 "INTR LIGHT" (7.5 Amp),
#7 "BACK UP" (7.5 Amp), #8 "not used", and #9 "FR ACC SOCKET (10 Amp)
in the Driver's Fuse/Relay Box.
To further narrow down the source of your draw, pull each of these fuses one at a time.
No, that was not a "typo" There are 2 fuses marked "BACK UP" and are both 7.5 Amp and one is
in the Underhood Fuse/Relay Box and the other is in the Driver's Fuse/Relay Box. (I checked this 3 times just to make sure.)

My 2004 Kia Optima keeps killing batteries. I've put 2 new batteries in the last 6 months. I just put the new one in and it was dead after not driving it for 3 days. If I unhook the battery it is fine...


Sounds like a parasite. Shut off the car for about two hours, this will allow all of the computers to go to sleep. Connect an amp probe on the positive terminal of the battery, on most newer cars, 50 miliamps or less is all the current draw that the car should have. If it is more, remove one fuse at a time, checking the current draw. Lets have an example:
Current draw after two hours = 3 amps, so I remove the fuse for the cigarette lighter, when i check the amp probe, the reading is still 3 amps, this tells me, since i have removed power to this circuit, that it is not my parasite. So, moving on, I remove the fuse for my engine computer, I check the amp probe, the reading is still 3 amps, again, since I have removed the power source to this circuit, and the reading stays the same, it means that this is not the parasite in my electrical system. Moving on, I remove the fuse for my blower motor (the fan for your heater and ac) when i check the amp probe, the reading is 47 miliamps, since the reading is less than the previous reading, and i have removed power from the blower motor circuit, it means that the parasite is in the blower motor circuit. Hope this helps!!

My 2000 chevy blazer is having battery issues.i have had the battery a year and replaced the altinator a year ago,and something keeps draining the battery.I can't seem to figure this one out


if you have an volt meter capable of reading amperage you can check for a draw fairly easily.

Turn off the vehicle, remove the key, unplug any accessories from the 12 volt (cigarette) outlets, and disable the under hood light if equipped.

Disconnect the negative battery cable from the battery. Install your amp meter in series, one lead on the negative terminal of the battery and one lead on the negative terminal of the battery cable. You should see less than .050 amps. It may take up to 20 minutes for everything to power down so don't worry if you see more right away.

If after 20 minutes it does not drop lower than .050 amps you have a draw. You can start removing fuses from the underhood fuse block one at a time. If the draw goes away than you have just narrowed down the possibilities to that circuit. Post what fuse you pulled and I can help you further.

If none of those fuses cancel the draw remove one of the test leads. Open the drivers front door and remove the courtesy lamp fuse from the instrument panel fuse block located behind the access panel on the end of the left side of the dash. Reinstall test leads and then start removing those fuses one at a time.

Some common draws are aftermarket stereos, glove box lights, visor mirror lights,

Can you pls tell me where the fuse box is


Fuses are located either in the engine compartment or passenger compartment fuse and relay panels. If a fuse blows, a single component or single circuit will not function properly. Excessive current draw is what causes a fuse to blow. Observing the condition of the fuse will provide insight as to what caused this to occur.
