I hear a chime, see indicators on the IPC, and a gauge sweep.......so it's obviously not "completely dead".

- how do you know the battery is good? Has it been tested?
- If above is yes, what is the measured voltage at the battery?

If battery is good then check the battery connections and the cable connections from the battery to the starter solenoid and to the engine block.
