DR-5B Detonation Sensor Wire to Logic Module

1. With detonation sensor electrical connector disconnected, place ignition switch in Off position.
2. Remove jumper wire from detonation sensor electrical connector terminal.
3. Connect an ohmmeter between detonation sensor electrical connector terminal and terminal No. 24 of logic module blue electrical connector.
4. If ohmmeter indicates continuity, replace logic module.
CAUTION: Before replacing the logic module, make sure the terminal in cavity No. 24 is not crushed so that it cannot touch the logic module pin.
5. If ohmmeter does not indicate continuity, check wiring for an open circuit.
