Hi Bigjohn and welcome to the forums.


It might help if you could give some more details such as the make of charger and model, or even the model of van you have as as someone may have had this problem before and know what causes it.


It seems strange the charger appeared to operate again before getting hot after 3 days. Clearly something is faulty and whilst most likely the charger is faulty there is a chance it may be an extrernal load making it run at full power output.

It might be worth while testing it with the output unplugged and see if it still gets hot. However it certainly sounds like it could well be faulty and a new one should cure and also get your mains hook up indicator light working again.


1. Does your battery stay charged when not on hook up indicating something causing excessive drain?

2. Do you have a voltmeter so you can do some tests?

3. What make is the charge and model?

4. What make and model/age is your Motorhome?

5. What capacity is your battery and type?

6. What other equipment do you have on board the vehicle powered by the leisure battery?

I suspect that a low voltage output from your charger is used to enable the pilot on your display. Replacing the charger with one purchased as a direct replacement should make it work again. But replacing the charger with something else is unlikely to light up your display.


If your control panel has a voltmeter function then you could use this to check if the battery is charging, because if it is the hookup is connected!!


In our van the tel tale that the hookup is connected is that the microwave oven display lights up!

Alternatively a small neon added to a prominent mains socket is a simple and effective mains indicator.


A range of chargers were recently reviewed / tested in the April MMM.
