Operation when the motor is running
Assoonasthemotorisrunning,arelayconnectsthestarter
batteryandthemotorhomebatteryinparallel.Therefore,the
dynamo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oagain.
Tochargeadischargedmotorhomebatteryoptimallywhile
driving,disconnectthe12Voperation oftherefrigerator
andturnoasmuchequipmentaspossiblethatuses12V.
