Cranking Battery Cable
The cable assembly designated for the engine starting battery is unique in that in addition to the
Red (+) and Black (-) wires, there is a purple wire that must be attached to a 12 Volt source,
which is switched on and off by the engine ignition key switch. Use the supplied quick connector
to attach the purple wire to any key activated 12 Volt source. It is important to note that the
“charge on the run” circuitry will not operate unless the purple wire is connected to a 12 Volt
source.
