2007 31 PC Factory-installed 200 Watt Sub hums when the Battery Breaker is on

Here's my challenge:

50K + in damage from Hurricane Sandy resulting in all new Engine room electrical-related items including the 6 Watt trickle charger for my Generator Battery. The Charles Charger was mounted high enough on the forward engine room bulkhead and as such, did not suffer saltwater intrusion.

The symptom:

1. Turn on the Battery Charger breaker down below and the Factory-installed sum hum's like crazy. Turn off the Battery Charger breaker and the hum goes away.

2. Disconnect the "new" 6 Watt trickle charger from the Generator Battery, turn on the Battery Charger and the hum does not return.

My reasonable assumption is that the "new" 6 Watt charger is bad. Am I missing anything?
 
Electricity is wacky...could be a ground issue with the new 6 watt charger.

I would check the ground on the new unit.
