12 volt supply pulsating
Hi
Returned to caravanning after a break of 18 years. We have a Lunar Clubman 2004 and have used it over the winter. This morning when checking the internal lights I find that they are pulsating and battery level drops substantially. The battery is not fully
charged but is registering in the green section of the meter. Even switching to the charger alone and isolating the battery does not stop the flicker. Checked all 12 v fuses. I have removed the battery and am charging it wth an external intelligent charger
but evven without the battery onboard we still have the problem. All the 12 volt systems are affected (fridge light, loo flush, radio etc. No issues with the mains supply as kettle, heater etc are working fine.
Am I looking at a replacement charger or is there a simpler solution that I have overlooked?
Any advice gratefully received.
