TROUBLESHOOTING
GENERAL TROUBLESHOOTING GUIDELINES
This section outlines several tests to systematically identify and isolate problems
with the electrical system and the drive train. This troubleshooting section is
organized into three basic problem sections: Electrical System, Console
Diagnostics, and the Drive Train. Perform the tests in exactly the same order as
written. Refer to the "Parts Removal and Replacement" section of this manual
for any disassembly and assembly instructions. To order a replacement part, or to
get help with the troubleshooting process, contact the Customer Service Depart-
ment of StairMaster Health
&
Fitness Products, Inc. at (800) 331-3578.
International customers should contact their local distributor or call
(425) 823-1825.
SYSTEMATIC ELECTRICAL TROUBLESHOOTING
The electrical system of your Momentum systems cycle ergometer has five major
components: the power control board, the alternator, the load resistor, the main
cable assembly, and the console. In order to identify the component that is
causing the problem, you must systematically test the entire system. You will
need a Volt-Ohm meter (multimeter) and alligator clips to conduct portions of the
following procedures. The console. battery. and power control board are not
serviceable by the owner. If any of these parts are inoperable, they must be
replaced. Attempted repairs to the console. battery, or the power control board
will void the warranty.
1.
Remove the side covers.
2.
Test the battery connection at the power control board (PCB). Measure
VDC between yellow test points 7and 10 (near the battery connector) of
the PCB for a minimum of 6.0 VDC. If the measured voltage is 6.0 VDC or
more. Skip to step 6.
3.
Test the battery. Unplug the battery connector from the power control
board and locate pin 2and pin 3 in the end of the battery connector.
4.
Use a voltmeter to verify that the voltage between pin 2 (negative) and
pin 3(positive) is a minimum of 6.0 VDC. Install the battery charger for
at least 24 to 48 hours if the voltage measured is below 6.0 VDC. It is
