I have a simplistic question. Did the battery replacement "cure" the
problem?

Yes.

I also tried installing the old "not quite dead yet" battery in again. 3 times
installed, 3 times set the ELT off.

I planned to take a variable power supply and work the voltage down slowly from
6 volts to zero, but can't find my power supply.

Also, faxed ACK on Thursday. As of today, nothing heard... but maybe they were
busy with Arlington.
