That ground strap story is interesting.

Usually Packard put the chassis ground strap on the transmission cross member. However, if the battery cable was not going to the engine then that would create big problems.

The usual method to test this problem is checking the voltage between battery ground and the body, and battery ground and the motor with accessories turned on the the motor on fast idle. A ground problem would show up as more than .4 volts with 0 - .2 volts ideal.
