Lower Board Checkpoints
Console Cable Connection
Procedures:
Using a dc volt meter (if non-auto ranging set for the 20vdc range), test the voltage at the grey and again at the white console cable
connections using the yellow, orange or red wires as ground. Two tests are to be performed; test once with power on before the treadmill is
started and again after Start is pressed. Note: this is the same procedure as the upper board console cable connection. If results vary from
the upper board, the console cable is the likely cause and a continuity check should be performed.
Desired Results:
The voltage charts contain typical desired results on a fully functional system. A variance from the norm would indicate a defective compo-
nent.
