uhmmmm, like i said,
nothing electrical works. nothing, nada, zilch ...
all dark & dead.
battery has ~13V on the terminals. can't test under load, because nothing electrical is working ...
all dead, no idiot lights, no fuel pump, no relay click, no nothing ...
Andy
What voltages have you measured around the vehicle? A 12V fuel pump or idiot light will do nothing with less than 3-4 volts across it.
Like Harry Truman said, "the buck stops here".
Likewise, the electons stop somewhere between your battery and loads. If the battery is measuring 13V and nothing works, chances are your battery is ok and there is some major open circuit. Do you have a fusable link in the positive voltage path from the battery?
Start with the battery and radiate outward. If battery is 13V and voltage at parking lights is 0V, 13V is being dropped somewhere.
With key on, lights on, ..., check battery posts, then battery terminals, then follow wires from the battery. Like to the starter. To the ignition system. Somewhere you will measure 13V, then 0V.
Check battery posts to their terminals. This is where I found 7V of drop when my car wouldn't start.
Measure all voltages from chassis since this is the ground return for the entire electical system.
Check battery ground wires to the battery by measuring voltage from chassis to battery ground.
BTW, I love an electrical challenge like this. The problem will be a simple one: a battery, a wire, a fuse, or a ground/power connection. The electrical systems in these cars are so simple (but not trouble-free) that everything can be worked on unlike modern vehicles with multiple computers, processors, sensors, servos, and miles of wiring.
If I were closer, I'd help you fix this so I can take a ride in your 3.6L and compare it to my 3.7L (1.7L and 2.0L
)
Good luck.
