15. Replace the screened cap.
GO TO point 14
16. Reconnect the following components:
- Shielded cap
- H.V. coil supply connector
- ECU interface wiring:
GO TO point 17
17. With the engine idle, measure the induced
voltage produced by the H.V. coil primary. In this
case, use the digital multimeter and the peak vol-
tages adaptor.
1 - 12 = 300V (peak)
Minimum allowable voltage ³ 200V (peak)
Standard voltage at start-up= about 350V
(peak)
YES point 18 NO point 19
N.B.
USE THE ADAPTER WITH THE POSITIVE
PROD ON PIN 12. IF THE ENGINE DOES NOT
START, CHECK THE INDUCED VOLTAGE AT
THE START-UP

18. The system is efficient, check timing.
19. If the detected voltage is much lower than the minimum allowable, check the core dwelling time
reported in the «parameters» function of the diagnostic tester
