SPEED CONTROL PROBLEMS
to Figure on page. 34). The relay indicator should light up. If it does, go to step #4. If the relay indicator does not light up, the relay assembly circuit board must be replaced. Replace the relay assembly circuit board and retest the machine.
4.You must check the cable assembly for continuity if the relay indicator lit up when you jumped tabs #1 and #5.
a.Unplug the main cable from the position labeled 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 #1 at the console connector end of the console cable (refer to Wiring Diagram). Place the other lead on pin #1 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.Check continuity in both ends of the main cable assembly at pin #5.
d.If there is no continuity in the cable assembly at either pin, replace the cable assembly and retest. If there is continuity in the cable assembly at both pins and the relay resistor indicator is not lit, the console is inoperable and must be replaced.
5.Have your assistant step on the staircase (leave the console in the ATTRACT mode) while you check the field indicator light. It should be flickering. If it is and you still have a speed control problem, go to step #6.
If it is not flickering, ensure the following: the console cable is connected to the console; the console/main cable connection is secure; the connector at position J1 on the relay assembly circuit board is securely connected; that there is continuity in the cable assembly. To check for continuity:
