SPEED CONTROL PROBLEMS
a.Unplug the connector at position J1 on the relay assembly circuit board. Disconnect the console cable from the back of the console. Set your multimeter to the continuity check mode; on most meters this will be the resistance or ohms setting.
b.Place one lead of the multimeter on pin #2 at the console connector end of the console cable. Place the other lead on pin #2 at the end of the main cable you disconnected from the relay assembly circuit board. You will get a reading of near zero ohms if there is continuity in the cable assembly.
c.If there is no continuity in the cable assembly, replace it and retest. If there is continuity in the cable assembly and the field indicator light is still not flickering, contact the Customer Service Department at
6.If the field indicator was flickering while your assistant was on the machine and you still have a problem with speed control, you need to test the alternator.
a.Disconnect the white wire (labeled positive output on the alternator) and the brown wire (labeled “Field” on the alternator). Use a jumper wire to jump the Field and positive output terminals of the alternator.
b.Have your assistant step onto the staircase. Does the staircase slow down? If it does not, you need to replace the alternator. If the staircase does slow down, contact the Customer Service Department for further assistance.
c.Replace or exchange the alternator with another alternator you know is good and retest the machine.
d.Test the load resistor as outlined in the "Load Resistor Test" section of this Manual. If the speed control problem still exists, contact the Customer Service Department at (800)
