Charging System with Battery Brain and
Introduction
The ASAP has two batteries, one battery is located under the hood. This battery is for the Polaris
Ranger functions. This battery starts the engine, runs the ignition system, headlights, turn signals,
power steering system and the optional auxiliary cooling fan.
This battery is for all Polaris chassis related
The other battery is located under the driver's seat (this can be accessed by pulling up on the
front edge of the seat, lifting in the areas between the driver's legs and the passenger legs).
This battery is the deep cycle battery; it runs all emergency lighting, dome lights, windshield
wipers, generator starter, A\C control panel, 12 volt outlet in the patent compartment. And any
other optional equipment that may be on the unit
The ignition switch and master switch do not have to be "ON" in order to charge batteries
Polaris Battery:
The Polaris battery is charged two ways:
1. By the Polaris engine
2. By the onboard battery charger
If the Polaris engine is running the engine charges this battery.
If the shoreline is plugged in, the onboard battery charger charges the battery.
If the generator is running the onboard battery charger charges the battery.
Any time the generator is running the onboard battery charger is on and charging batteries
The only time the onboard charger is not charging the Polaris battery is if the ignition key is in
the "ON" position or the Polaris engine is running. This is to prevent double charging.
Note: There is a solenoid that only allows one device to charge the Polaris battery at one
time. By turning the ignition key to the "on" position, a solenoid breaks the connection from the
onboard battery charger to the Polaris battery.
As a safety measure this solenoid does not allow current from the battery charger to enter the
system when the Polaris engine is running. The engine stator charges the battery when the engine
is running.
Q. When would you find yourself in this type of situation?
A. If you were driving the ASAP and running the generator.
Q. Is it okay to drive the ASAP with the generator running?
A. Yes
Q. Is it okay to have the shoreline plugged in all the time?
A. Yes, anytime the ASAP is stationary and you have access to 110 volt outlet, it should be
plugged in. The battery charger will automatically shut off when your batteries are full.
