Have an HDS 10 on the bow of a friends Puma FTD. We are on vacation and had a major thunder storm this morning. After the rain cleared the unit will not turn on. Checked and have power to the unit but nothing happens. HDS 8 in the console works fine as do all other electric functions (pumps, lights, horn, etc). Could water have entered the HDS 10 and casued it to fail? If so, will leaving it in front a a fan help? Is there a way to reset the unit? If it totally failed would water intrusion be covered by warranty? This unit is less than a year old and has been in the rain before. Any ideas appareciated. Thanks on advance.
