Another weird electrical issue thread
My daughter's Explorer had been giving random dash warnings (low tire pressure, check charging system) for weeks. Then the other night the dash flicked, the lights went out, the trans went to limp mode all within a block of the house. She limped it home and while still running off the battery, all lights and dash were dark. Looked like a classic alternator failure to me.
I bought a replacement alternator from Adavance at 5pm on Christmas eve and planned to replace it the day after Chrismas.
I get the old alternator out, take it to Advance to verify that it had failed. They put it on the test rig and it tests OK. Because the issues had been intermittent I decided to install the new alternator anyway figuring it was the classic "the car is never sick when the mechanic is around." Meanwhile, I also charged the dead battery.
After wrestling with the belt tensioner I get it all back together, it starts fine, no dash lights, and then about 30 seconds later the "check charging system"
light comes back on. I recheck all of the connections and it all looks good. I drive the car to Advance on the battery and they put their gizmo on it. Zero volts form the alternator.
They are willing to let me try another alternator but that was a lot of work. Plus, since the old one checked out OK, something else is wrong. The Advance clerk suggested a fusable link between the fuse box and the alternator is bad.
Does anyone have any idea where that fuseable link is?
Is there a specific fuse or relay in the fuse box that relates to the alternator?
Anyone have a diagram of the fuse box? I have no owners manual. I bought the car used from a dealer (why do they often steal the owners manual anyway?)
Any ideas are welcome as this fricken car is driving me crazy. It is a shame. the engine runs great but the trans is goofy and the electrical system is goofy.
