•   Connect and disconnect test instruments only with engine stopped and ignition system switched off.
•   Engine tester or individual instruments for measuring rpm and dwell angle which cannot be connected to diagnosis socket may be connected for tapping signals to cable connector of switching unit terminal TD only.
•   To prevent faulty measurements the trigger clamp should be attached directly behind ignition distributor to ignition cable cylinder 1.
•   The shorting equipment in engine testers (comparing cylinders, cylinder balance) which are stopping the engine upon actuation may no longer be used, since the current flow through ignition coil might lead to destruction of ignition coil.
•   The separate ignition coil test may now be made only with the additional adapter cable, with a defined ignition coil load, to prevent damage
to ignition coil.
