House battery charging issue
We can normally run 4-5 days on the house batteries (two six-volt "golf cart" batteries in series, for 12 volts) on our 2006 Itasca Navion. We're just back from a week and a half trip (total mileage ...

Hi Phil,
Clearly there is something else going on. My charging paths are twin #8 wire with automatic breakers at 50 amps each. Since I changed to the telecom jars, I get almost no charging from the engine--and the voltage quite quickly tapers to 13.2 volt. One wire is OEM from the under the hood fuse box, and the other, which I added, comes directly from the starter battery. I do have manual control of each of the solenoids.
I may have damaged my alternator over the 105,000 miles and 9 years of ownership as I did often run the water heater. This was with the 875 amp-hour battery bank of 7 Walmart Marine jars. I would do 20 minutes on which would knock the voltage down to 12.5, and then 40 minutes off. Actually that is how I came up with the 20 minute duty cycle--I did not want to run the starter battery down.
