Solving Modern and Classic Electricals

Solving Modern and Classic Electricals

Land Rover’s reputation for temperamental electrics is well-earned, but it’s often misunderstood. Whether you’re dealing with the legendary Lucas wiring in a Series III or the complex CAN bus networking in an L322 Range Rover, the root cause is usually the same: moisture, vibration, and poor previous repairs. At Landymen, we spend a significant portion of our week with a multimeter in hand, tracing “ghost” faults that have baffled general garages.

In older models, the issues are usually mechanical—corroded earth points, brittle insulation, or switches that have simply worn out after 40 years of service. We often see auxiliary fuse boxes that look like a bird’s nest because someone wanted to add work lights or a winch without using a proper relay. We take pride in stripping those back and loitering the wiring properly, using heat-shrink tubing and factory-spec looms to ensure reliability in the middle of a muddy field.

In modern Rovers, the challenge is software and sensors. A “Suspension Fault” or “Transmission Failsafe” message can be terrifying for an owner, but it’s often down to a single corroded height sensor or a dying battery. Modern Land Rovers are incredibly sensitive to voltage drops; if your battery is at 80% health, the ECU might start shutting down “non-essential” systems. We don’t just clear codes; we find the source, whether it’s a pinched wire in a wheel arch or a leaking sunroof.
