Oil pressure light

[RedFred]

Hi,
I've got a query about the oil pressure light that comes on (and goes off after a short while) after I have taken a sharp right, usually going round a roundabout!
There are also some other electrical issue, such as; new leisure battery not holding charge and the electical indicating panel by the fridge no longer working.

Can anyone recommend someone who may be able to help in the Oxfordshire area?

Many thanks,
Dominique
