December holidays are just around the corner and it is a good time to check your
basic 12V equipment to make sure you have an enjoyable holiday.
Batteries - Test all batteries including dual batteries and caravan batteries, make
sure they are well maintained, clean and fully charged. If in doubt have them load
tested or replaced. It is a good idea to test the capacity of the batteries to make
sure they will power your accessories for any given time.
Fridges – Clean and test all fridges and fridge cables and plugs. Make sure the connections
are safe and there are no loose connections. It is a good idea to run the fridge
in the vehicle on 12V to make sure all is as it should be.
Lights – Test all lights and torches. Test all plugs and leads to ensure they are
safe with no loose connections.
Charging Systems – Test all battery chargers. Solar and Mains chargers should be
tested for serviceability and loose connections, pay particular attention to corrosion
and moisture if they have been in storage.
Dual Battery Systems and Caravan / Camper systems – These should be carefully inspected
for damage, corrosion, loose joints and voltage drop. It is important that the input
voltage from the cars charging system is very similar to the charge voltage being
received by the auxiliary batteries, any voltage drop of 0.3V or more should be investigated
and faulty parts replaced.
Spare Parts – It is always a good idea to have a basic tool kit and spare parts.
Common parts are fuses, wire, plugs, tape and always remember to pack your multimeter.
All electrical work and battery maintenance should be carried out by experienced
persons, explosive gases and chemicals are present in batteries. There are also shock
and fire hazards when working with electricity.
