Some advise is needed with respect to the replacement of
the factory installed 24VDC to 12VDC DC to DC Convertor.
We are about to install our Icom M802/AT140 SSB Radio.
The existing 12VDC wiring system is quite mess and
includes a separate 12VDC battery that was used for the
previous SSB installation.
I have heard that an Isolated ground DC to DC convertor
should be used. These are used in systems that are ether
positive ground or with floating ground systems.
I am pretty sure that our vessel (SM#196) does not have
a positive ground system.
Did Amel built their boats with a floating ground?
What does this mean with respect to installing a DC to
What are the ramifications for using a non isolated DC
to DC convertor?
Any help understanding this is much appreciated.
