Alternator → 100 A charge fuse → battery, the case earthed to the engine, and the warning lamp fed from ignition and returning on the L terminal (lights with ignition on, engine off).

Battery → 150 A fuse → starter relay → starter motor, with the ignition switch driving the coil. The classic crank circuit.

Stop cooking the switch: the headlight switch now only triggers a relay, and the lamp gets a short fused feed straight from the battery.

Fan relay driven through the radiator thermal switch, with a fused feed and a documented earth. Override switch parallel to the thermal switch.

Fused pump feed through a relay; the trigger runs from ignition (or a kill switch), and the pump earth returns to the chassis.

Master kill switch first, then a 300 A fuse, contactor and the winch motor — with the hand controller on the coil side.

A connector-first diagram: vehicle switches feed the plug pins, the trailer lamps terminate on the other side — the netlist chains straight through.

Aux battery behind a 100 A+ isolator relay; the link switch only drives the coil. Keeps the cranking battery safe from accessories.
