Hv Coil Secondary Check; Specific Tooling; Electric Characteristic - PIAGGIO Carnaby 125 Service Station Manual

Carnaby 125 - 200
Electrical system
- HV primary coil check
Disconnect the control unit connector and check
that the cable between terminal No. 3 and terminal
No. 8 is not interrupted (see figure).
If non-conforming values are measured, check
again the HV primary coil directly on the positive
and negative terminals. If non-conforming values
are measured, repair the cable harness or else re-
place the HV coil.

Electric characteristic

High voltage coil primary check
0.21 ± 0.025 Ohm

HV coil secondary check

Disconnect the spark plug cap from the HV cable
and measure the resistance between the HV cable
terminal and the HV coil negative terminal (see
figure).
If non-conforming values are measured, replace
the HV coil. To carry out a more complete diagno-
sis, check the peak voltage with the multimeter
adaptor.
