We have 330 Grady Express, purchased new in 2007, and the charger has failed. Product support on line tells us that the charger has "been electronically disabled to output" because of safety reasons. This model 2722B is a 30 Amp, 3 storage, 2 output version. It seems that it is out of production. Any recommendations for replacement? Our last boat never needed a new charger in over 18 years, so this failure is a surprise. We are in the Bahamas, and the boat is in constant use. We expect 82 degrees on Christmas. Happy Holidays, Grady owners!
