3. Disconnect the DC cable from the left side panel. Set the voltmeter to VDC and test for 12 to 19 VDC in pins #1 (+) and #2 (-). Replace the power supply if the voltage reading is outside the specified range. 4. Remove the bottom cover and connect the DC cable to the power connector on the left side of the frame. Locate the black and white wires on the backside of the power connector. Page 44 ELECTRICAL TROUBLESHOOTING 5. Follow the white power connector wire to the where it plugs into the main cable white wire, and disconnect it from the main cable white wire. 6. Set your voltmeter to VDC. Connect the positive lead of your voltmeter to the white wire from the power connector and touch the gray casing of the alternator with the negative lead of your voltmeter. 7. DC voltage measured should be 12 to 19 VDC. Replace the power connector if the voltage is not the same value as in step 3. Connect the two white wires. 8. Remove the console knobs from the back of the console, lift the console up, and disconnect the 20-pin main cable from the console. 9. Test for 12 to 19 VDC in pins #1 (-) and #10 (+) in the main cable connector. Replace the main cable if the voltage reading is not the same as in step 7. 10. If all voltage readings have been within the specified range and the console will not power up, the console should be replaced. Alternator Test 11. Check for loose wiring connections on the alternator, diode, and load resistor (see Final Assembly Figure). 12. Perform the Positive Output to Field test on the alternator: • Disconnect the power cord from the electrical outlet. • Remove the black wire from the B+ terminal on the alternator. • Remove the brown wire from the field terminal on the alternator. Page 45 ELECTRICAL TROUBLESHOOTING • Place a short wire with alligator clips on the B+ terminal and the field (FLD) terminal of the alternator. • Step on the machine for approximately 10 to 15 seconds. • If full resistance is achieved during this time, your alternator has correct current flow. If no resistance is achieved, replace the alternator. Diode Test 13. Remove the brown wire and diode from the field terminal of the alternator and set your voltmeter to the Ohms setting. 14. Place one lead from the voltmeter on each end of the diode, and then reverse the leads. A diode that is good will show a high reading in one direction and a low reading when the leads are reversed. Replace the diode if the readings recorded are both high or both low. Resistor Test 15. Remove one wire from the load resistor (see Final Assembly Figure) and place one lead from the voltmeter on each of the threaded posts on the load resistor. Replace the load resistor if the voltmeter does not read 0.5 Ohms (± 10%). 4600/4400 CL Battery Test 1. Remove the mid cover and top covers and unplug the battery from the power control board. Locate pins #1 & 2 in the end of the cable. Use a voltmeter to verify that the voltage is a minimum of 6.1 VDC. Reconnect the battery back to the power control board and install the battery charger for at least 24 hours if the voltage measured is below 6.1 VDC. Note: You can use the machine while the battery recharger is connected. 2. Remove the console knobs from the back of the console, lift the console up, and disconnect the main cable from the console. Page 46 ELECTRICAL TROUBLESHOOTING 3. Step up on the machine. With the voltmeter set to DC voltage, test for greater than 6.1 VDC in pins #1 (+) and #10 (-) in the main cable connector while stepping. Replace the main cable if the voltage reading is less than 6.1 VDC. Next, check for continuity in the main cable (see Final Assembly Figure). 4. If all voltage readings have been within the specified range and the console will not power up, the console should be replaced. Alternator Test 5. Perform the Positive Output to Field test on the alternator: • Unplug the battery from the power control board. • Remove the black wire from the B+ terminal on the alternator. • Remove the brown wire from the field terminal on the alternator. • Place a short wire with alligator clips on the B+ terminal and the field (FLD) terminal of the alternator. • Step on the machine for approximately 10 to 15 seconds. • If full resistance is achieved during this time, your alternator has correct current flow. If no resistance is achieved, replace the alternator. Resistor Test 6. Unplug the load resistor from the power control board and set your voltmeter to Ohms. Place one lead from the voltmeter on each of the threaded posts on the load resistor. Replace the load resistor if the voltmeter does not read 2.5 Ohms (± 10%). 7. If the problem still exists, contact the Customer Service Department at 800-331-3578. Page 47 4600/4400 PT/CL CONSOLE DIAGNOSTIC TESTS The following tests are performed while the console is in the “SELECT WORKOUT” mode. If the console fails any test, the console should be replaced or exchanged. To return to the “SELECT WORKOUT” mode, press either [CLEAR] or [START/ST...
