Checking the supply voltage - Figure 15
Technical conditions
| Contacts | State | Voltage |
| 15 and mass | Ignition ON | battery |
Make sure the ignition is off.
Turn on the ignition.
Measure the voltage between the low voltage terminal of the coil and ground.
If the voltage does not meet the specifications, check the wiring.
Checking the resistance of the primary winding - Figure 16
Technical conditions
| Contacts | Resistance |
| 1 and 15 | 0.67-0.82 Ohm |
Make sure the ignition is off.
Disconnect the low voltage coil wires.
Measure the resistance between the low voltage terminals of the coil.
Checking the resistance of the secondary winding
Note: There is no data on the secondary winding resistance.
