DC Electrical work

12 or 24 volt electrical wiring

The RV wiring system can be complex because of all the different appliances connected to the 12-volt batteries, and the 240 AC supply, some appliances are even connected to gas. So it helps to have a Technician who understands the wiring systems of the RV.

Our experienced technicians can help with diagnosing and fixing a wider variety of issues, including:

  • Intermittent faults that only show up under certain circumstances. This could be due to the fact that the vehicle is in motion some of the time and subject to vibrations.
  • Repairs to the 12 or 24-volt direct current wiring in the living space as well as the DC wiring in the cab part of the vehicle.
  • Repairs to the AC 240 wiring.
  • Our Technicians are also very familiar with visual and audio wiring systems that relate to the TV, satellite and sound of a motor-home or caravan.

It doesn't matter if the vehicle is an American import, European import or a Kiwi built unit, we can fix it.

More about 12/24 volt systems

12 or 24 volt electrical wiring (sometimes called auto electrical wiring), in motor-homes and caravans can get quite involved compared with standard auto electrical work. This is due in part, to the vehicle electrical system being partially connected to the living space electrical system.

A good 12 or 24 volt DC setup should work problem free, linking both the vehicle wiring and the house wiring. If the system is out of balance, we find that the house DC system voltage starts draining which in turn, drains the vehicle DC system. This can lead to the vehicle failing to start so the house DC system should be disengaged in such cases.

The RV wiring system can be complex because all sorts of sensitive appliances are connected to the 2 battery banks, such as satellite systems, solar systems, TV's, wifi, pumps, fridge etc. Over the years we have come across some very interesting wiring, done by people who knew enough about wiring to make the connection, but not enough to know what effects their work might have on everything else in the vehicle. The cost in hours of finding the cause of a problem once it is created, can add up. Sometimes it is better to leave things to the Technicians who do it on a daily basis. Our expert Technicians consider the whole system and have a good understanding of the future implications of adding any component.
