Repair Procedures

PROCEDURE 1: Check harness for voltage

1.1 Remove the console.
1.2 Turn meter on setting to test for DC voltage.
1.3 Put one lead on pin 2 and the other lead on pin 3. There should be around 6 volts.
1.4 Remeber that you must be pedaling the unit in order to get the voltage reading unless you have
the unit plugged into an outlet.
1.5 If there is no voltage, go to procedure 2.

PROCEDURE 2: Check for DC voltage from Console

2.1 Remove the cover beneith the seat to access the controller.
2.2 Turn the meter on setting to test for DC voltage.
2.3 Leave the harness connected to the controller and put the leads on the 2nd and 5th wires. (You
will probably need to remove some of the glue from the back of the harness)
2.4 Press start and set the resistance to level 1. At level 1 there should be aprox .130 volts. At level
2 there should be aprox .78 volts. Level 3 should be aprox .82 volts.
2.5 If the reading is not close to these numbers, the problem is either the console or the harness. If
the readings are what they should be, go to next step.
2.6 With meter still on DC setting, put leads into the back of the 2 pin connector as pictured below.
This is the connector for the wires that go to the brake coil.
2.7 At level 1 the voltage reading should be zero. At level 2 and above, if you get any reading the
controller is working.
2.8 If you dont hav any voltage, the controller needs to be replaced. If there is voltage but still no
resistance, the brake coil needs to be replaced.
