System Notes — ELECTRICAL AND STARTING SYSTEM
The electrical and starting system covers the battery, starter motor, alternator, wiring harness, relays, switches and the instrument panel. It carries current from the batteries to the starter to crank the engine, and from the alternator back to keep the batteries charged. Because these machines work in dust, vibration and wide temperature swings, connectors corrode, harness insulation chafes against the frame, and starter solenoids burn out from repeated short cranks. Parts in this group are usually replaced on a symptom basis — slow cranking, a dash warning, lights that dim under load, or a no-start condition traced to an open circuit.
System Notes — AIR INLET AND EXHAUST SYSTEM
The air inlet and exhaust system covers the air cleaner housing and elements, intake piping, turbocharger, aftercooler, exhaust manifold, turbo mounting hardware and gaskets. It delivers clean, dense air and carries hot gas away. On this group, the two dominant failures are dust ingress and heat cycling: a leaking intake joint lets unfiltered air straight into the cylinders and dusts the rings in a few hundred hours, while exhaust manifold and turbo flange gaskets crack from repeated heat cycles and start whistling or sooting. Parts are replaced when boost drops, the intake tract shows dust trails past the filter, or a soot streak appears at a joint.
