RULES TO BE FOLLOWED IN THE EVENT OF INTERVENTION ON THE ELECTRIC SYSTEM - APE
TM
A) ESSENTIAL WARNINGS
The check or in any case the intervention on the circuits of the devices for the electronic ignition can
be done with relative ease by the electronic repairers of Service Station Workshops; it is essential,
however, that they take observe the notices below, since, in case of failure to observe, they could
irreparably damage the devices.
All inspection operations of the system involving disconnection of cables (verification of the connections
and devices that are part of the ignition circuit, therefore including the main key switch) must be made
with the engine off: otherwise the control unit could be irreparably damaged.
The ignition circuit works on AC, and obviously,
must be definitely separated from that of DC
In fact the latter, powered by the battery and dy-
namotor, serves only for the service user groups
(city lights, stop, horn, lights, headlight, etc.).
KEY:
1 = Red (direct current)
2 = White (direct current)
3 = Grey - Red (direct current)
4 = Purple (alternating current engine stop)
5 = Black (ground)
6 = White - Red (direct current)
* = Connection connected to the red cable of the condenser charging coil.
** = Connections with electronic ignition.
If there is a connection of two circuits, i.e., if the
ignition one was routed by the DC, there would
be instantaneous deterioration of the control
unit. It is therefore necessary and important
that, in case of removal or disconnection of cables,
particularly of those which depend on the main key
switch and the control unit, during reassembly pay
attention to correctly reconnect each cable to the
