To prevent injuries to persons and/or damage to the injection and
ignition system, the following must be observed:
♦ Do not touch or disconnect ignition cables when the engine is
running or being turned at starter speed.
♦ Ignition must be switched off before disconnecting and re-
connecting the cables of the fuel injection and the ignition
system as well as of the test equipment.
♦ If the engine must be operated at start speed without it starting,
as for example, when checking the compression pressure, re‐
move the fuse for the voltage supply of the injection valves and
the ignition coils from the fuse holder ⇒ Current flow diagrams,
