Ron, et al,
A corollary of Kirchhoff's law says that all currents are equal in a
series circuit and all voltages are equal in a parallel circuit. Tapping a
load across
of the carts the
duty cycle.

This is a very common issue in aircraft. The most obvious question is
does your jeep use 2 each 12 volt batteries? If so, simply connect
your radio
batteries.

Depending on the load connecting across one battery
I have installed land mobile stuff in Gov Surplus fire equipment, (right
next to Fort Hood) and 24 volt Forestry Service and 24 V street
sweeping equipment over the years. I will NOT install any equipment
across one battery in a 24 V string.
Take it somewhere else and let them do it. I

Steve, this confuses the dickens out of me. I now understand the
reverse polarity part, but won't the protection diode be reverse
direction, and
This assumes that the installer did not fuse the + lead to the radio.
Normally a 25 to 35 watt radio has a 15 amp fuse but you might be
surprised how many times the power cable has been cut and no fuse.
Anyhow, without a fuse, the reverse protection diode or transorb in the
radio tries to
