Your battery connections and fuses may be fine but is your battery dead ? I drove to work one day and when I came out of work I had no power to anything. I used my key to unlock the door, opened the hood and even the little light under my hood would not light up. I got a boost, drove the Explorer to the dealer, left it running but locked, and when they tested the battery it had a dead cell, so they replaced the battery.
Is your battery dead ? or a bad battery cable connection ?
This requires a lot of battery power. First, check your fuses. You may have blown them(one). Then check your battery for a charge.
Check your fuses... Also check your wiring connections... Exc.
Check to make sure all connections to the starter are properaly installed, Check battery connections to see if their is corrision, or check cables from battery to other connections are not loose, if so, correct them, you can also check for burn't out fuses or relays related to the ignition.
Most likely the problem is your alternator....the battery light actually does not monitor battery condition, only the charging system. I'd check the voltage regulator and the fuses first. The fuses are the cheapest fix and the voltage regulator will run about 25% less than an alternator.
The fuse panel is on the drivers end of the dash ( the removable plastic cover is visible with the drivers door open ) and there are fuses and relays in the POWER DISTRIBUTION BOX in the engine compartment ( Ford states to disconnect your battery before servicing anything in the PD BOX , which means your Explorer would have to relearn its idle , the clock and radio stations would have to be reset etc )
According to my 2001 Sport Trac Manual Fuses 4,5,23 @ 32 are not used for anything.
The fuse panel is under the dash panel on the drivers side , and the power distribution box is in the engine compartment ( Ford states before servicing anything in the PD BOX in the engine compartment to disconnect the battery )
Is this an automatic or manual transmission?
Check all the fuses, check fusible links, exc.
If the headlights flash on and off, there may be a problem with the bulbs or fuses. There may also be a problem with the battery connections or wiring.
You might want to check the starter, but first tighten the battery connections first. The same thing happen to my wife's car. I tighten the battery connection and the lights came on and car started.
