Default caravan charger u/

Hi all,well another weekend and another problem !
arrived on site and plugged in the mains-coupled up the water and switched
on the pump-no led..strange
have a check round and noticed one of the 6 amp mains mcb had tripped,reset
and tripped straight away-switch off internal charger and ok,switch on
charger= trip
change mcb=still same
remove charger & strip down but nothing burnt or blown(including internal
3amp mains fuse?)
unplug everything 12v from charger=no different,still trips mcb
conclusion is that its u/s
its from a swift challenger 1996 and says its a INTER-POWER 10amp by
plug-in-systems hull
any ideas if it can be repaired or replacement cheaper ?
howie
ps bought a car charger from halfords to get me thro the weekend as van
battery was flat ;0(

Hi Howie

Very difficult to diagnose, but sounds like the PSU that has gone, but at 10
Amps that sounds a little low any way, I would look for something like a 25
Amp replacement, poss the low current output has knackered the PSU.

Don't reply on a car type charger, they can get up to 20Volts and could over
charge a battery, and poss damage some internal electronics.

Also don't skimp on a decent PSU as it will cost you more in the long run

If the internal mains fuse on the charger is on the charger's input and
is not blown you should be looking at the cable between the charger and
the mains mcb. You could separate the charger from its supply cable and
check each part individually.

I would doubt there are many, if any old uncontrolled output chargers
still for sale.

Default caravan charger u/s

thanks for the prompt replies,i accept the better psu comment -but can i ask
if a low output one might be ok as in
CTEK MULTI XS 3600 12V BATTERY CHARGER
i dont use sites without EHU but i suppose a low output charger will take
ages to bring a low battery back to full charge
ref dougals comments, it makes sense - a faulty cable would do it but ive
unplugged the mains from the charger(leaving the cable attached to the
switch and its ok)
its just the same happens if you switch on the on/off switch on the back of
the charger which is the other side of the internal fuse-i fully expected
the fuse to have gone but its ok -possibly its a slow blow and the mcb
reacts quicker ?

Hi Again

Don't use the CTEK type chargers as a replacement for a PSU !

A CTEK is great if you remove the van and charge it, but they are not
designed
to run equipment in the van, as they are only about or 6 amp, also these do
a
pulse type charge, and relay on the feed back from the battery, so if you
were running
some thing like a pump it could damage the charger if the battery was low
for some
reason.

What you need is a Regulated power supply @ 13.8 Volts with current supply
of at least 20 amps, the 13.8 Volts, will make sure the battery is never
over charged, and supply power to any applicences like Pump, lights, and
things like 12volt TV etc, its surprising how quick the calculation of the
power adds up.

Is it an MCB - or is it an RCD, or a combination thereof? If the latter, it
may be tripping due to an earth leakage problem (which only needs a few tens
of milliamps) rather than because of an over-current fault.

It's still possible that it could be an over-current fault of course, since
an MCB would trip more quickly than the time taken to blow some types of
internal fuse - which may explain things.

If it is over-current, chances are that there is a short in a diode or
capacitor in the PSU. If you can diagnose that, you may be able to repair it
by replacing the relevant component.

The CTEK outputs 3.6amps maximum. That is fine for charging the
battery, but nowhere near what you might need to keep everything
running without discharging the battery. Strip lights can take 0.5 amps
each, the pump 2 or 3amps etc..

MCB's usually do react quicker than wire or glass fuses, but are you
sure it is just an MCB? Could it be an RCD?

The latter can trip simply due to a small amount of leakage to earth.
Power supplies usually have filters on the inputs between L+N to earth
which can sometimes become a bit too leaky and trip RCD's.

Assuming the plug you refer to is a kettle type plug, could you perhaps
try plugging the unit in at home and see if anything trips? It would
confirm the RCD/filter theory.
