Nope. The only external connections are the socket (3 pins) and Bat lug. My plug for socket has just the two wires. Another piece to this puzzle is the idiot lite for the charging system doesn't come on. Even when the ignition is put in the on position with the engine not running.

In looking thru the schematics for 98 the one I posted is the only one on the Ford DVD for that year. It may be possible that it is an early production 98 with 97 loom. The only one close I found between 97 and 99 with just two wires was listed for a 5.0 Explorer rather than your 4.0. However I am posting it just in case it leads you to the problem circuit as it is wired substantially differently. It would appear your problem as indicated by others is the power circuit to the instrument cluster. Check fuses and ensure the fuse fits tightly and that the wiring connections all the way thru are clean and tight. Could even be loose at the cluster itself.

Well, every fuse I can find, inside and out is good and well seated. Guess now it's time to enter the dreaded dash and go after the bulb. I don't suppose there's a way in without pulling the dash out is there? Maybe somekind of bulb trap door that is known only to super-techs. Before diving in, is there any place Ford might hide a fuse besides the power distribution box and the interior fuse panel?

Both diagrams above show a 7.5 amp fuse in the interior fuse panel, so that should be the only fuse. There is a "15" beside the fuse in the diagram, so it may be labeled 15 in the fuse panel.
I have never worked on a later model truck like yours, but more than likely you will have to pull the whole cluster. And in the process of pulling the cluster and un-plugging the connectors and such, you may end up fixing the problem if you find the bulb is good, and don't see anything wrong, because it may be just a bad or corroded connection. You can take a pencil eraser and clean any connections you may find.

My sincerest thanks to everyone who became involved in this saga. When I had checked the fuses, I did so by probing the back of the fuses while they were still in place. After going back and pulling the suspected fuses out of the panel......what can I say? oxidation got in the way again. Cleaned the pins on the fuses...scraped a little on the terminals in the fuse box with a jewelers file........reinserted the fuses and.....voila'....Thanks again to all......knorton
