Reading through the archives on alternators the Battery Shack in Marathon, FL is a possiblity for a 100 amp replacement. Problem is they aren't answering at the phone numbers on their web site (877-743-0011 and 305-743-0011). Someone told me that I may be at the wrong site (http://thefloridakeys.com/batteryshack/). Anyone know if they're still in business?Thanks,Joe Mullee
