Ford Ranger Check engine light on
If you own a 2005 Ford Ranger and the battery goes dead, with the check engine light on and the seat belt light on when the key is NOT in the ignition, check for corrosion at the back of the fuse box for fuses #11 and #15. If you find any, disconnect the battery and clean the fuse box with electrical contact cleaner. Allow the spray cleaner to dry completely. Apply a small dab of dielectric grease to the area to cut down on corrosion. Then reinstall the fuses, reconnect the battery and charge it before starting.
