Rained hard the other day and unfortunately we drove through a fairly deep puddle on our way home. Suddenly there are multiple systems warnings flashing and the battery died the next day. Warnings include: battery no charge, low refrigerant, a/c shut down, traction control, etc. The only one that stays on is the 'battery no charge' the others come and go. Changed the battery, tested the old one and it was taking a charge fine. Changed the alternator and the warnings are still flashing??? It's got to have something to do with the water in the engine, too much of a coincidence. Any ideas?
