dash lights on after deep flooded river crossings

[whirly03]

i went through a lot of rivers at the weekend 2 inch above the bonnet in most places, it would seem i have picked up an electrical fault, basically all my lights on the dash have turned on EG the turbo red light,battery ,timingbelt and oil ,, at one stage on the drive back they flickerd on and of and the battery was charging again, but later they all came on again,, any ideas what has happened? has my alteranter shit its self? ive checked the wires but cant se anything obvious like a lose connection or anything .. they could be a short but im unsure where to start looking,, any help would be great

thank you in advance
