Because once you start using electrics you load the alternator which cannot cope .Probably find your battery is low also if you load test it and if original , may need replaced

It is a brand new battery , alternator was replaced 17/10/17, , but went through a 12"deep Ford about 8 weeks ago , and problem seems to have started then , is this linked?

Water and car electrics / wiring dont mix , especially with nowadays set ups . I'm surprised the garage has not load tested both the alternator and battery , simple tests . If the alternator has been or is faulty it will have run down the new battery which may need a charge to bring up to full capacity . Another thought , the wiring and plug to the alternator should be inspected for water ingress.
