2000 ford excursion battery draw

How much drain? All vehicles have some drain for the 'keep alive' function. If you are sure that all fuses (cabin And underhood) are ok. One common problem to look at is the plug connection on the firewall. Unplug it and check for water/corrosion on the male and female connectors in the plug. If all ok, time for more comprehensive diag. Instrument displays are controlled through a module. Power windows are completely separate circuit. v This time of year, I would be checking all harnesses for critter damage. Hope this points you in a direction. Have to start with the basics.

• Power distribution box (BJB) Fuse 8 (15A) (underhood fuse box )
• Any other light's not working ? headlamps ,license plate light's ?
• Symptom Chart Condition Possible Sources Action
  • The parking, rear or license lamps are inoperative
  • BJB Fuse 8 (15A) (Super Duty and Excursion).
  • BJB Fuse 6 (20A) (Motorhome).
  • Circuitry.
  • Headlamp switch.
  • GO to Pinpoint Test R .

On the 2000 Jeep Grand Cherokee the # 15 fuse is the IOD circuit. (Ignition Off Drain) The # 12 fuse is the power windows. Both fuses are 50 amp.

This IOD fuse #15 powers the distribution box that contains the 50 amp fuse. Pull each fuse in the under hood.

Pull each fuse in the under dash. Check for on the passenger side floor is an additional fuse panel.

Before going to far suggest at night checking for any lights lit. The draw is about right for a small light bulb.

Typical draw for parked car is around 100 milliamps

Suggest that you disconnect power to the car for several minutes. Reconnect the battery. The object is to reset the body electronics module.

If the computers in the modules get a glitch they can cause a drain. By cycling the power, disconnecting battery, they will reset to factory settings. Reported it can take up to 20 minutes for the circuits to drain before you can reset!.


The Jeeps have several modules that can cause a drain

the following web site does a great job of explaining all that is going on. What appears to be simple to troubleshoot is not so easy. He comments about delay before sleep are important. Testing after overnight may result in a different drain rate. Make sure that your battery meets specifications. In 2000 the drain rate may be relatively high and the reserve capacity of your battery low.

Hope this helps?

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.

Here are the warning signs of a bad fuel pump for your Ford:

• Engine "chokes" or struggles to maintain speed.
• Noises, backfires and a sputtering engine.
• Hesitation at start or take-off.
• A bad fuel pump can overheat, causing the engine to overheat.
• Any of the above issues along with a "Check Engine" light.

Check fuses 52 15A and 51 15A in the underhood fuse box. Check the Blower motor relay behind the right side of dash. Check the fan control amplifier (controls fan speed) behind right side of dash. Sound more like a blown fuse or bad blower motor relay

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.

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.)

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,

inside the hood fuse box the relay is located take for over night and see if you there is still a voltage draw replace
