Some additional characteristics of the battery isolation manager include:
1. e isolator electrically delays connecting the house batteries to the vehicle charging
system for approximately 15 seconds, to allow the alternator time to reach full charging
ability.
2. Aer this initial time delay, the isolator senses the voltage of the vehicle charging system.
e isolator connects the house battery to the vehicle’s charging system only when the
chassis charging system reaches the correct voltage.
3. If the vehicle’s charging voltage drops below 13.2 volts for a period of 4 seconds, due to
low idle speed and/or excessive load, the isolator will disconnect the house batteries until
the vehicle’s charging voltage returns to a level of 13.2 volts or above. For this feature, there
is a built-in delay period of approximately 10 seconds.
4. e isolator allows the chassis battery to be charged by the house charging device (usually
the converter or inverter) when 120 VAC is in use (shore power or generator power).
5. e isolator allows vehicle starting from the house battery(ies) via the Emergency
(Auxiliary) Start Switch.
Emergency (Auxiliary) Start Switch (if so equipped)
Your motorhome may be equipped with an Emergency (auxiliary or Aux) start switch.
Located in the vehicle’s cockpit, near the drivers seating area, this switch connects the house
battery to the vehicle’s starting circuit. is feature is used for situations when the chassis
battery is too depleted to start the vehicle on its own. Connecting the house battery to the
chassis battery may provide the needed energy to start the vehicle’s engine.
To operate: Depress the 'EMER START' switch, located on the front driver’s dash, and hold.
Next, use the ignition key to start chassis engine. Release the 'EMER START' switch aer the
engine has started.
It is strongly advised to turn o all 12 volt DC devices before using the emergency start
feature. is will help ensure that all available energy stored in the house battery can be used
for vehicle starting.
NOTE: Do not hold the ignition key in the
start position for more than 30 seconds. Be
careful not to run down the auxiliary battery
as this could leave you without 12 volts DC
power.
