I just thought of something - when are you checking the draw from fuse 25?
Here's why I ask:
Most 1995 and newer Ford/Mazda products have modules in them which will remain in "standby" mode for a period of time after the vehicle is shut off. While in this mode, they will draw current which is excessive by established standards for normal current drain. However, after no longer than 1 hour of inactivity (no change in state of door switches, door handle switches, hood switch, trunk/tailgate switch, ignition switch or key-in-ignition switch), they should go to sleep, and total current draw should be less than 50 mA.
Before we head down a wrong path
1. Fully charge the battery
2. Hook up meter as described in next test - make sure it's visible from inside the vehicle
3, Locate and Pull all fuse covers inside vehicle
4. Go to the restroom
5. Then grab a flashlight,
6. Get a good book, (you're going to be inside the truck for a while)
7. You'll need needle nose pliers and perform the following test:
|Customer Concern:||Electrical drain causing the battery to go dead. When pulling fuse #25 (7.5 amp) from the interior fuse box the drain goes away.|
MY summary of the issue - please correct me if I am wrong.~~~~~~~~
|Tests/Procedures:||1. Install an ammeter between the battery negative post and cable to identify the amount of amperage draw that is present on the vehicle. A normal draw will indicate approximately 250 milliamps (mA) for 45-60 minutes after all doors are closed with the ignition switch off. After that time frame, the Generic Electronic Module (GEM) will enter a sleep mode and the total vehicle drain should decrease to indicate 50 mA or less. |
2. If the amperage draw is normal when initially turning the ignition switch off with the doors closed, but it stays close to 250 mA after the 60 minute wait period, remove fuse #25 to see if the mA draw drops to less than 50 mA indicating a defective GEM.
3. If the draw is higher than either of the normal specification values, start pulling all interior fuse box fuses one at a time until the draw drops under an acceptable level to determine the circuit and components which are influencing the excessive draw. Leave the fuses out as they are pulled to prevent awakening any modules which could result in falsified readings.
4. If all interior fuse box fuses are removed and the draw is still excessive, start removing the under hood fuses one at a time until the drain drops to an acceptable level to identify the circuit of concern. Again leave the fuses out as they are pulled to prevent waking up any on-board module.
5. Once the fuse of concern has been identified, reinstall the fuse and start disconnecting all related components of that circuit to identify if the draw is related to a component issue or a circuit problem.
