DR-9D Throttle Position Wires to Logic Module

1. With ignition switch in Off position, disconnect logic module red and blue electrical connectors.
2. Connect an ohmmeter between blue connector terminal No. 1 and red connector terminal No. 25.
3. If ohmmeter indicates resistance, replace logic module.
CAUTION: Before replacing the logic module make sure the terminals in cavities No. 1 and 25 of the logic module connectors are not crushed so that they cannot touch the logic module pins.
4. If ohmmeter indicates an open circuit, check wiring between terminal No. 25 of red connector and throttle position sensor.
