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.
