engine must be running (such as when driving
down the road). This will prevent excessive
discharge of the house battery.
NOTE: The holding tank heater pads are
electrical resistant-type heating
elements. This type of heating element
typically uses a large amount of current
while operating. If the tank heaters are
used without a recharging source, they
will drain the house batteries in a
relatively short period. Typically, the
batteries would not support overnight
heating without a supplemental charging
source.
