Problem with 12v System

[Andrew_374385812]

Hi,

Whilst away in the caravan last week the 12v system stopped working and I am looking for some advice on getting it sorted.

Over a period of a couple of days everything that is 12v slowly stopped working (lights, water pump, extractor fan etc). I have checked the status of the battery and it is still fully charged which seems to suggest that it is not the charger at fault? I am thinking it may be an earth fault but am not really sure where to start with identifying the problem.

Any help that anyone could give with either supplying a potential solution for the problem or any other ideas on identifying the fault if it looks as though I am wrong would be gratefully received.

I will potentially get an electrician to look at it but would like to have an idea of what the problem is before parting with cash if it is just a "loose wire".

I have a 2003 Compass Omega 524

Many thanks in anticipation

Andrew

Andrew,

You say the systems slowly died - which implies a failing battery. So how did you check that the battery was OK?

But you also need to check for a poor or corroded connection, broken supply or return wire (no earth on 12 volt systems), a defective fuse or faulty switch.

Do you have a reasonable quality multi-meter, about 5 metres of test probe extension cable, and are you happy to use it to diagnose a fault?

You need to start at the battery and check everything, item by item until you find the problem.

Hi, problem solved, thought i'd post the solution in case it helps anyone in future.

It was the battery charger - new one

I do hope it was'nt just the fuse blown on your old charger....

Some types have a blade fuse buried in their workings, which it is not obvious to check, unless you know it is there.
