another aux battery malfunction, '12 ML63
Popped the side cover in the back after doing a little research on here to find it....
Shows 11.5 volts not running and the same running.... The main battery terminal under the hood is 14.1 running so we r charging.... but it's not charging the rear/aux battery
When does the aux battery charge ? is it a low voltage that triggers something ? Is there way to trick a sensor to charge the rear aux battery so I can check if it's really the battery, the sensor or the device that does the charging ?
Look like a bit of pain to swap it.... pull the side cover I assume....
Thanks
Mike
