Operation when the motor is running
As soon as the motor is running, a relay connects the starter
battery and the caravan battery in parallel. Therefore, the dyna
-
mo charges both batteries. If the D+ signal no longer sits close
to the dynamo, the two batteries will be separated from each
other again. In this way, the starter battery cannot be discharged
by equipment in the motor home.
The 12 V supply for the refrigerator only functions when you
are driving. If the motor has stopped, the 12 V operation of the
refrigerator is automatically turned off again.
To charge a discharged caravan battery optimally while
driving, disconnect the 12 V operation of the refrigerator
and turn off as much equipment as possible that uses 12 V.
Checklist
• Turn off the motor.
• Switch on the 12 V master switch.
• Turn off all equipment that uses 12 V.
• Start the motor.
