Charging coil

See fig. 094.
In case of failure of one ignition circuit, the 2 single-pole plugs
of the red charging cables may be interchanged for failure
tracing.
If the failure remains on the same circuit, the electronic module
is the cause and the respective module has to be renewed (see
para 13.4.12).
If the failure passes on with the ignition circuit, the charging coil
Q for ignition circuit "A" or W for circuit "B" is the cause. In this
case the stator must be removed (see para 13.4.14).
Check charging cable for damage. Check resistance value
3
with ohmmeter, see para 11.5 and 13.4.7. If required, renew the
fig. 094
complete stator.

Double ignition coil

See fig. 095.
If the failure of a single spark plug or 2 spark plugs is noticed, check the
connections and the resistance values of the respective double ignition
coil, see para 11.5, 13.4.7, 13.4.8 and 13.4.11.
Assure the iron core Q is not loose. If required, renew the double ignition
coil. In this case the disassembly work as described below is necessary,
see para 13.4.9 and 13.4.10.
