Rippling lights

[waffler]

New caravan with a BCA charger. On mains hook up 12 volt lights flicker- for good period of time then steady then flicker again. No problem off hookup so clearly it is to do with the charger.Anyone else met this one? (On my previous van it could ripple when the battery was very low.)

Have you tried checking the main battery terminals.

If the cable screws are not tight that could be the problem
