WHEELCHAIR USER
As a manufacturer of wheelchairs, Invacare endeavors to supply a wide
variety of wheelchairs to meet many needs of the end user. However, final
selection of the type of wheelchair to be used by an individual rests solely
with the user and his/her healthcare professional capable of making such a
selection. Invacare highly recommends working with a certified rehab
technology supplier and/or a member of NRRTS or RESNA.
RESTRAINTS - SEAT POSITIONING STRAPS
Invacare recommends that wheelchair users NOT be transported in vehicles
of any kind while in wheelchairs. As of this date, the Department of
Transportation has not approved any tie-down systems for transportation of
a user while in a wheelchair, in a moving vehicle of any type.
It is Invacare’s position that users of wheelchairs should be transferred into
appropriate seating in vehicles for transportation and use be made of the
restraints made available by the auto industry. Invacare cannot and does not
recommend any wheelchair transportation systems.

This Section Includes the Following:
Field Load Test
Motor Testing
Motor Brush Inspection
Electro-Mechanical Parking Brake Testing
FIELD LOAD TEST (FIGURE 1)
NOTE: The following test can also be performed through the controller of the wheelchair along
with a remote programmer. Refer to the
chair.
Old batteries lose their ability to store and release power, due to increased internal
resistance. This means that as you try to take power from the battery, some of that
power is used up in the process of passing through the battery, resulting in less voltage
at the posts. The more power drawn, the lower the voltage available. When this lost
voltage drops the output 1.0 volts under load (2.0 for a pair), replace the batteries.
Testing under load is the only way to spot this problem. While special battery load
testing equipment is available, it is costly and difficult to transport.
ELECTRONICS MANUAL supplied with each wheel-
TROUBLESHOOTING
Use a digital voltmeter to check battery charge level at the charger connector. It is located
on the base of the wheelchair frame.
NOTE: READ the instructions CAREFULLY
before using the digital voltmeter.
Battery Charger
Connector
(-)
(+)
NOTE: Invacare recommends that ONLY
qualified service personnel perform this test.
1. Ensure that power is OFF.
2. Make sure battery is fully charged. An
Digital Voltmeter
extremely discharged battery will exhibit
the same symptoms as a bad one.
FIGURE 1 - FIELD LOAD TEST
3. Remove the footrests from the wheelchair and place the CASTERS of the wheelchair
against a wall, workbench or other stationary object.
4. Place the voltmeter leads into the charger plug on the wheelchair. Most digital voltmeters
are not affected by polarity, however, analog meters (meters with swinging needles) can be
and should be used carefully. A good meter reading should be 25.5 to 26 VDC.
5. Have two (2) individuals (one [1] on each arm) apply as much downward pressure as
possible on the arms of the wheelchair.
6. Turn the wheelchair ON and push the joystick forward, trying to drive the wheelchair
through the stationary object. This puts a heavy load on the batteries as they try to
push through the stationary object. Read the meter while the motors are straining to
determine the voltage under load.
NOTE: If the voltage drops to less than 23.5 volts from a pair of fully charged batteries while
under load, they should be replaced regardless of the unloaded voltages.

SECTION 2 TROUBLESHOOTING
MOTOR TESTING (FIGURE 2)
NOTE: This procedure should only be
performed on wheelchairs with the
conventional motor/gearbox assembly. For
gearless/brushless motors, there are no
serviceable parts. Return motor to
manufacturer for testing.
1. On the 4-pin motor connector, locate
the two (2) contacts in the red and
black housings.
2. Set the digital multimeter to measure
TROUBLESHOOTING
ohms (Ω).
3. Measure the resistance between the
two (2) motor contacts.
Ohmmeter
Ohmmeter
NOTE: A normal reading is between 1 and 5
Motor Connector
ohms (Ω). A reading of 0 ohms (Ω) or in
excess of 15 ohms (Ω) indicates a problem.
Motor Connector
FIGURE 2 - MOTOR TESTING
High readings are generally caused by bad
connections and/or damaged brushes. Contact
authorized dealer or Invacare.
MOTOR BRUSH INSPECTION (FIGURE 3)
NOTE: This procedure should only be performed on wheelchairs with conventional motor/
gearbox assembly.
There are two (2) contact brushes on
STORM motors located under the brush
caps on the motor housing. If these caps
are hard to remove they are either
overtightened or the motor has become
very hot. Let motors cool. If caps still
cannot be removed, it is recommended
that the motor be sent to Invacare
Technical Services for inspection/repair.
NOTE: It is very important to note which way
the brush comes out of the motor. The brush
MUST be placed into the motor exactly the
same way to ensure good contact with the
commutator.

INSPECTION
3G Storm Series® Wheelchairs 18 Part No. 1104849
SECTION 2TROUBLESHOOTING
Once the motor brush caps have been removed, pull the brushes out of the motor. The
end of the brushes should be smooth and shiny and the spring should not be damaged or
discolored. If one or both of the brushes are damaged, only the damaged or worn
brushes need be replaced. It is very important that any time a brush is replaced, it must
be “burned in”. This is accomplished by running the motor for one hour in each
direction with a half hour break in-between. This should also be done with little or no
load on the motor, i.e., put the wheelchair up on blocks so the drive (large) wheels do
not contact the ground and run the wheelchair. A motor with only one brush replaced
will only carry a small percentage of its rated load capacity until the NEW brush is
burned in.
ELECTRO-MECHANICAL PARKING BRAKE TESTING
(FIGURE 4)
NOTE: This procedure should only be performed on wheelchairs with conventional motor/
gearbox assembly.
1. On the four-pin motor connector, locate the side by side connectors in the black
housings.
TROUBLESHOOTING
2. Set the digital multimeter to read ohms (Ω).
3. Measure the resistance between the two (2) brake contacts. A normal reading is 100
ohms (Ω). A reading of 0 ohms (Ω) or a very high reading; i.e., MEG ohms or O.L.
(out of limit) indicates a shorted brake or an open connection respectively. If either
condition exists, send the motor to Invacare Technical Service for inspection/repair.
CAUTION
A shorted electro-mechanical brake
will damage the brake output section
in the controller. DO NOT connect a
shorted electro-mechanical brake to
a good controller module. A shorted
brake MUST be replaced.
