Bigpower, you would have received better answers in the Alpine forum. My Alpine has an Echo charger as part of the Xantrax system. I believe all Alpines of that era had them. The Echo charge is supposed to provide up to 15 amps of current to the chassis batteries when the following conditions are met:
Plugged into shore power or generator providing 120-volts AC
House batteries fully charged
Difference in voltage between house batteries and chassis batteries is greater than 0.5 volts
My Echo charger doesn't charge intermittently. I've been using an external battery maintainer but I plan to install an Amp-L-Charge next week.
