7000 PT /STEPMILL /GAUNTLET™ ELECTRICAL TROUBLESHOOTING
Please refer to your owner’s manual for detailed instructions. If you do not have an owner’s manual please call
our Customer Service phone number to order one.
A. Power
1. Verify AC voltage at wall outlet (110 – 120 VAC).
2. Verify AC voltage at end of AC cord (110-120 VAC -if cord detaches from power supply).
3. Verify DC voltage at power supply. You should get a minimum 12 VDC if your DC cable detaches from
the power supply, and a minimum 10 VDC if your DC cable does not detach from the power supply and is
prior to 10/27/97.
4. Verify VDC at end of DC cable.
5. Verify VDC on pins 4 and 5 at the end of the grey cable.
6. Verify VDC at pins 4 and 5 on relay board while someone is standing on stairs (be very careful, the use
of alligator clips is imperative). Voltage under load should be between 9-12 VDC if you have an older
style power supply, and no less than 12 VDC on the newer style power supply.
B. Grey Cable (does apply to the 7000 PT)
1. Perform the AC tap, alternator test, 107 enter 1 (this tests the blue wire - Pin 3). While standing on the
stairs, the lower left LED should light up on the console indicating a good circuit. The alternator should
provide resistance.
Check for loose connection/bad crimp at alternator.
OHM grey cable pin 3 to blue wire and end of grey cable, Acceptable resistance is <1.0 OHM.
Test all other wires and crosscheck wires against all others by leaving the probe in pin 3 and
testing each pin at the end of the grey cable. All tests here should give full resistance readings.
2. Perform the field terminal test, 107 enter 2 (this tests the brown wire -Pin 2).
a. While walking on stairs, there should be no resistance. Use the speed up and slow
down arrows to give full resistance/no resistance.
b. The lower left LED should light only when machine has full resistance.
3. Check for loose connection at alternator.
4. OHM grey cable pin 2 to brown wire and end of grey cable molex. Acceptable resistance is <1.0 OHM.
5. Cross check brown wire against all others by leaving probe in pin 2 and testing each pin at end of grey
cable. All tests should give full resistance readings.
