Leisure battery problem?

[Hamish the highland hymer]

Hi im new to the site, and have not long bought a hymer b544, which i love, ive done my maiden trip
But on my return saw that the engine is not charging the leisure battery infact the voltage drop when the engine is running,
It charges from mains hook up and get power from my solar panel but with the engine on it appears to drain the battery quite a lot.
Any ideas would be great
Thanks
Mark
