Diagnosis & Testing: Notes
CAUTION:
DME ignition system voltage is extremely high. Contact with current-carrying parts while engine is running could prove fatal. Always turn ignition switch "OFF" or remove battery ground cable when connecting testers or replacing system components. High voltage is particularly present at spark plug, distributor, and ignition coil connections and at terminal 1 of the control unit. Do not attempt to check ignition system by a sparking test of spark plugs. This may destroy ignition coil or control unit.
