'92 ford explorer, 150,000+ miles, 4.0 litr.
The EEC 30 amp maxi fuse under the hood keeps blowing out when I turn the key to the on position (engine off). I have changed the main battery cables, but with the same result every time, 10- 15 seconds the fuse is blown. Would appreciate any insight to what I could do next. Thank you.

i would start looking for a short somewhere. like a hot wire shorting out on the body somewhere. if not, find a schematic, and look to see what else runs on that circuit. it could be another electrical component gone bad that runs on the same maxi fuse you described causing it to blow also. hope this helps

Suggested Repair

Look for a short, such as a hot wire contacting the body. Use a schematic to identify other components on the EEC maxi-fuse circuit and test those parts, since a failed component on the same circuit can blow the fuse.

Conversation Summary

The owner of a 1992 Ford Explorer reports that the underhood EEC 30-amp maxi fuse blows 10-15 seconds after the key is turned on with the engine off, even after the main battery cables were replaced. The expert advises checking for a short to the body and reviewing a schematic for other components sharing that circuit that may have failed.
