I have a three bank battery charger in my Chris Craft. When the unit
is actually charging, it creates interfernce in the TV picture on my
boat and the boats in close proximity. Does anyone have any idea why
this is happening and what might be done to alleviate it? My
neighbors are ready to sink my boat. Thanks.

Simple answer is to run the charger during hours when others are unlikely to
be watching TV. ...

Add "Install ferrite beads like the ones found on some computer cables"
to the list of possible fixes. They're available at most electronic
stores (Radio Shack) and snap around the wire close to the charger.

Your charger has what's called a switching power supply in it. Simply
put, the input power is converted to a much higher frequency, this
allowes the use of a much smaller transformer than you would need for
standard 60 Hz AC power. This makes the charger much smaller, lighter,
and cheaper. The noise you are getting is comming in on the power
line or the antenna. You might try a shielded antena wire, and if that
doesn't work, you may need a power filter. The folks at Radio Shack,
or someplace like that, may be able to help you.
