New owner of a XJ8 needing some info.

[RWW]

Hi all. 

I recently purchased a 2004 XJ8 V8 SE Auto. Everything was going great until it started raining. While driving I turned the wipers on and the engine cut off. The car still had Electrics, but the engine stopped dead.

Would anybody have a clue to why this might be happening.

Hi Robert, never experienced this cut out in any vehicle before, but would suspect a connection between the rain and the cut out engine, to have an electrical sub plot.

It sounds like a water ingress to an important part of the vehicle's electrics which was "loaded" when you turned on the wipers - perhaps a coincidence, but worth looking for commonality in the circuit - like ignition on.

Did it restart afterwards, or has it remained "dead" since occurring? You state "the car still had electrics", what do you mean by that? Were the lights on at the time and remained on, did the dashboard light up, did any warning lights come up, are there any stored codes to be read?
