|
- Connect the LED probe between terminals 2 (Fig. 128) and 3 plug ignition transformer circuits; - Press the starter (without touching the wires in the ignition transformer circuits); - The LED should blink. If not, faulty Hall sensor can be related to the ignition distributor, or system control unit; - Again, disconnect the tester and insert the plug into the connector (disconnecting the ignition); - To further narrow the search Probable cause, you can check the LED probe terminals "1" and "15" indicated in Fig. 126. When the starter LED should blink. Otherwise, replace the ignition coil with a powerful output stage;
