10.2 Electrical Cables
• If the belt is ok, look for any loose connections or wires around the power board or motor assemblies.
10.3 Test Motor
Put the climber in the Test Mode (see section 3) and run the motor in both directions by using the arrow keys.
If the motor is not running refer to section 10.5.
10.4 Motor Runs
If the motor runs, check that the motor shaft is not spinning inside the pulley on which the belt wraps and that
the motor does not have a stripped gearbox. If the motor shaft is spinning inside the pulley, remove the motor
assembly (see section 26) and tighten the set screws (see Fig. 5). Make sure that one of the set screws is on
the flat portion of the shaft. To verify that the motor does not have a stripped gearbox, look at the armature
shaft on the outside of the motor. If the armature shaft on the outside of the motor spins but the output shaft
and belt pulley do not, the gearbox is stripped. Replace the motor assembly.
10.5 Motor Doesn't Run

•
Unplug the motor cable from the power board assembly (see Fig. 16). Plug in the spare motor assembly and
see if it will run in both directions. If the spare motor assembly runs, replace the original motor assembly. If
you do not have a spare motor assembly, use an analog (not digital) meter (observe polarity!) to verify voltage
at connector J5 on the power board. (see Fig. 16). Place the climber in the Test Mode (see section 3) .
Measure the voltage across the two pins of J5 while an assistant presses the up & down arrow keys on the
console. J5 voltage with no load should read approximately 13 to 14 volts DC. If you do read the expected
voltage, replace the motor assy. If the voltage is incorrect replace each of these parts in the following order:
1. power board assembly (see section 29), 2. display ribbon cable (see section 31), 3. display board (see
section 30) .
