DC CABLE FOR HF
RADIO OEM Molex type 6 pin connector 12Volt DC Cable for HF Radios.
Requiring
a 12V (13.8V) DC cable for a TS-50 HF transceiver that is constructed
with a
OEM Molex type 6 pin connector
for the radio and 35A Anderson connector for the
power supply. This cable is a
standard arrangement for a large range of amateur transceivers from
most of the manufactures.
The OEM
Molex type 6 pin connector are rated at around 10Amps and therefore for
a typical HF
transceivers such as the Kenwood TS-50S that has a peak current loads
of 20Amps the Molex plug pins are connected in pairs to achieve
the required rating. See figure 1 and 2 for the pin
designations.
It is
important
that pins 3 and 6 are not connect as they are used for a 120 or 240VAC
supply in radios such as the Yeasu FT736R for example.

The
cable also includes two inline fuses, the
positive lead fuse for general overload current protection. The negative
fuse is primarily for vehicular installations to protects the wiring in
the situation were the main negative battery leads to the motor frame
is damaged and the large starting currents may find a path back
through the radio's negative connection that could result lead damage
and possible fire. While this cable is not
intended for vehicular installation it could conceivable be in the
future. The fuses are connected in opposite directions so that they can
not be inadvertently connected to the wrong wire and provide opposite polarity to
the radio.
