Electrical, battery & solar

Find the fault. Restore the power.

Practical diagnosis for the 12V systems that keep your motorhome, caravan or camper comfortable and ready to travel.

Testing an RV electrical and solar system

Electrical problems need careful diagnosis

When lights, charging, batteries, solar or connected equipment stop behaving normally, replacing parts at random can waste time. Lakes RV starts with the symptoms and works through the relevant 12V house systems.

Systems we can investigate

  • 12V lighting, connections and common supply faults
  • House batteries and charging behaviour
  • Solar panels and controller operation
  • Fridge connections and related RV fittings
  • Intermittent faults while travelling or parked

This describes RV house-system fault finding, not automotive engine electrical work or regulated certification.

What to include

Tell us the vehicle, what stopped working, when it happens, any readings and what has already been tried.
