Viv,

The problem with your generator may not have been the battery. It is quite possible the problem is the alternator. I had that problem this summer in Maine. Inopurtune timing, it failed on the only day/night we were to dry camp. We also could not open the coach windows for fresh air because of a reallly, REALLY hard rain followed up with some really, REALLY thick Maine fog. Sure glad we didn't eat tacos with the twins at dinner that night! Anyway, the alternator on my generator, a motorola unit is no longer in production. It puts out 37 amps when working properly. NAPA said they could get me one with the exact same body and mount dimensions but it did put out 65 amps. All that means is the battery would be fully charged a lot quicker. Bad news it would take three days to get it to the Rockland ME NAPA store. I had less than 24 hours to do something. NAPA put me in touch with a local Alternator/starter rebuilding shop. I dropped the alternator off at 4:45 in the afternoon and it was rebuilt by 10:00 AM the following morning. Repairs were completed in Bar Harbor thanks to Miles Circo and Jim Keller. Thanks again guys. Now if I could only get the Galley and Bedroon A/C compressor clutch to quit melting on me!
