Checking winding resistance
Primary circuit (A cylinders 1 -4, B cylinders
2-3)
Bring the probes of an ohmmeter into contact
with the postive strip (central pin) and the
negative strip (pin 1 for circuit A and pin 2 for
circuit B).
The primary circuit resistance reading on the
guage should be between 0.44 and 0.53 ohm
at 23 °C.
Secondary circuit (C cylinders 1 -4, D cylin-
ders 2-3)
Bring the probes of an ohmmeter into contact
between the two high tension outlet termi-
nals.
The secondary winding resistance reading on
the gauge must be between 4500 and 5500
ohm at 23 °C.
Recovery
Inhibition of injectors for cylinders in which
ingnition is not taking place.
Open-loop mixture control
Current command is de-activated in case of
short circuit to positive in order to try again
later.
If circuit is broken, or short-circuit to earth,
charge time is assumed to be dependent up-
on battery voltage.
Removing refitting
1. Disconnect HT leads from spark plugs.
2. Unscrew the bolts indicated and remove
the ignition coils
