Rene,as I posted previously. Do look at those connectors below the relay(s). My friend who looks after several cars on the race circuit & normal private ones. He says it is a known fault & sometimes you can actually see the evidence of “arcing”. He has had 3 cars with the same fault in the last 5 years iirc.
The auto electrician who solved the 1st one, said same fault as known on older Land Rovers.
