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%).

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.
2. Remove the console knobs from the back of the console, lift the console
up, and disconnect the main cable from the console.
3. Step up on the machine. With the voltmeter set to DC voltage, test
for greater than 6.1 VDC in pins #1 (-) and #8 (+) 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.
