Electrical System; Electrical Components And Connections; Main Circuit Breaker; Charging Your Batteries - Pride Mobility JET 3 Owner's Manual

Electrical System

The electrical system is powered by two long-lasting, 12-volt, deep-
cycle batteries. These batteries are connected in series to provide
24 volts of direct current (DC). The main electrical components con-
sist of the batteries, a battery charging system, the main circuit
breaker, the motor/brake assembly, and the controller (see figures 1,
2, and 4).

ELECTRICAL COMPONENTS AND CONNECTIONS

The joystick/controller is connected to the battery and the motors
through two electrical connections: the controller connector and the
charger harness connector. Both are located on the electrical con-
nector housing at the back of the power chair. See figure 4.
Controller Connector: This is where the controller is connected to
the batteries and motors.
Charger Harness Connector: This is where the charger connects
to the joystick/controller.

MAIN CIRCUIT BREAKER

The main circuit breaker is a safety feature built into your Jet 3. It is located at the back of the power chair. See figure 4. When
the batteries and the motors are heavily strained (e.g., from excessive loads), the main circuit breaker will trip to prevent
damage to the motors and the electronics. If the circuit breaker trips, allow the Jet 3 to ìrestî for approximately one minute.
Then, push in the circuit breaker button, turn on the controller power, and continue normal operation. If the main circuit breaker
trips repeatedly, contact your authorised Pride dealer.

CHARGING YOUR BATTERIES

The batteries are sealed and maintenance free, so there is no need to check the electrolyte fluid level. Deep-cycle batteries
are designed to handle a longer and deeper discharge. Though they are similar in appearance to automotive batteries, they
are not interchangeable.
CAUTION! Automotive batteries are not designed to handle a long, deep discharge, and are unsafe for use in
power chairs.
BATTERY CHARGING SYSTEM
The battery charger is essential in providing long life for your power chair's batteries. Your power chair may be equipped with
an onboard charger located between the batteries. See figure 2. The ammeter is located on the electronics connector
housing, for easy viewing. The 7.5 amp, in-line fuse is located under the electronics connector housing. The in-line fuse
protects the entire charger circuit from shorts or bad connections. The ammeter indicates the rate of charge necessary to fully
recharge the batteries. The ammeter is also a good indication of whether or not the charger is working. The ammeter and the
charger are functional only when the charger power cord is plugged into a wall outlet.
WARNING! You must recharge your Jet 3's batteries with the supplied onboard or off-board charging system.
Do not use an automotive-type battery charger.
To charge the batteries using the onboard charger:
1. Position the rear of your Jet 3 close to a standard wall outlet.
2. Be certain the controller power is turned off and the Jet 3 is not in freewheel mode.
3. Plug the charger lead into the receptacle on the connector housing.
4. Extend the charger power lead and plug it into the wall outlet. The Jet 3 incorporates an inhibit function that disables
the power chair when the charger is plugged into a wall outlet.
5. The ammeter will indicate how much charge is needed to fully charge the batteries. Wait about a minute for the
chargerto warm up. The ammeter may move up to as high as 4 amps, then gradually move back down to 0 amps as it
charges.
6. We recommend you charge the batteries for 8 to 14 hours. As the batteries charge, the ammeter needle will slowly
drop to the zero mark. When the batteries are fully charged, the needle will vibrate on or about the zero mark on the
meter scale.
