PROCEDURE (continued)

10.Connect positive voltmeter probe to the Idler / Engine protection PC board J1 pin 10 for Code 10856, (J31 pin 10 for codes 11199 and 11408). Connect the negative probe to a good chassis ground connection or the negative battery termi- nal.

11.Move the run/stop switch to “run” and read the volt- age within 30 seconds of switching to “run”.

If battery voltage is detected:

Test the flashing diode and resistor assembly, and the two diode and leads connecting the negative side of the D1 bridge rectifier to chassis ground. Also check all of the wiring and connections between the Idle / Engine Protection PC board, and the positive brush terminal. See the wiring diagram.

If battery voltage is not present, move the positive probe to J1, pin 1 for code 10856, (J31, pin 1 for Codes 11199 and 11408), and check the voltage.

If no voltage is present, check the run/stop switch, the circuit breaker, and all connections between the bat- tery, engine starter solenoid, ammeter, run/stop switch, idler switch, circuit breaker, and the idler/engine pro- tection PC board. See the wiring diagram.

If battery voltage is present at J1 pin 1for code 10856, (J31-pin 1 for codes 11199 and 11408), check that the Idler/Engine protection PC board is properly grounded. Lead wire #5A connects J1 pin 5 to chassis ground for code 10856. Wire GND-A connects terminal B1 to chassis ground on codes 11199 and 11408.

12.If the idler/engine protection PC board is getting power, and has a good chassis ground connec- tion, but is not producing flashing voltage during the first 30 seconds after power-up. Replace the Idler/Engine Protection PC board

When testing is complete, replace all covers and close the doors.
