Battery charging and battery chargers are often misunderstood – causing batteries to die before their time. This article explains why and how to avoid it.
Electrical (general)
RV Fuel cells – great idea, but cost is too high
Fuel cells for RVs are non-polluting and ultra-quiet. Whilst initially promising their initial and running costs still excludes general RV use.
Electrical converters in RVs – they’re unsuitable for free-camping
Electrical converters in RVs supply 12 volts from 230 volt power. They work well from 230 volts, but not for long-term camping. Here’s how to fix the problem.
RV electrical wiring – twin-wire or chassis return – here’s why twin-wire is usually better
Twelve-volt caravan systems may be twin-wire or chassis return. Twin-wire is usually best. This article explains why – and which to choose to avoid problems.
Variable voltage alternator problems with caravans – how to fix
Variable voltage alternator problems with caravans and motor homes arise when charging auxiliary batteries. Here’s why and how to fix them. These alternators are, in particular, installed on many post-2013 vehicles.
TV interference from LEDs – here’s what causes it
TV interference from LEDs is an issue worldwide. It is mostly caused by LEDs in the same home (or RV) as the TV. This can be checked by turning them off. Another indicator of TV interference from LEDs is good daytime reception until lights are turned on. In the worst cases, TV reception is unwatchable, or not even obtainable.
Caravan fridge problems – how to fix the most common faults
Caravan fridge problems are due to poor ventilation, inadequate cable size and/or insufficient power to drive them. Here’s how to fix them.
Inverters for caravans – and motor homes too
Buying inverters for caravans can confuse. Prices vary for products that may seem identical but are not. Here’s what to buy.
LiFePO4 jump starters really do work – they power other things too
Despite their very small batteries LiFePO4 jump starters really do work. This article by Collyn Rivers explains how and why. A lot of power (the rate at which energy is used) is needed. The amount of energy (the ability to perform work) required, however is surprisingly small. In the days of vintage cars, a strongish 55 kg (120 lb) girl could hand crank start a 4.5 litre Bentley with relative ease.
Caravan Fuses and Circuit Breakers – how to know which to use
Circuit breakers and fuses in caravans both cut the current, but in different ways. Here’s how to know which best suits circuits and appliances protected. Those for 230 volt grid or inverter supplied circuits must be specified and installed by a certified electrician – who will install circuit breakers etc anyway. Circuit breakers and fuses for RVs (for 12/24 volt circuits) can be self-installed by those familiar with such work.
