Testing the Selettra ignition
Some of the Selettra components can be subjected to a resistance test.
A digital ohmmeter should be used to test Selettra ignition components. Do not use an analog measuring device as it is not accurate enough.
Note
Do not check the components when they are still hot! You have to let the components cool down to room temperature before testing them!
Insert a probe into each end of the two wires after they have been disconnected from the stator coil.
For an analog stator, it doesn’t matter which probe is used on which wire.
Note
When testing the ignition coil, check directly on the ignition cable and not via the spark plug connector.
Units can operate slightly above the recommended range with test results.
If the readings are in the lower end of the scale, but the system is working properly, damage can be assumed.
To be on the safe side, the component should be replaced with a new one, as a short-term total failure can be assumed.
Recommended range
| Stator Type | Stator Type Measured value (Measurement with direct voltage at approx.20°C) | Number of windings |
| KZ 2200 90/94 48mm | 102 Ohm ± 10% | 2200 Windungen |
| KZ 3200 90/94 48mm | 162 Ohm ± 10% | 3200 Windungen |
| P3356 90/94 58 mm | 115 Ohm ± 10% | 2700 Windungen |
| NO2019 90/94 034-IG-14 | 57 Ohm ± 10% | 2400 Windungen |
| A11 90/94 58mm | 200 Ohm ± 10% ca. 180 – 220 Ohm | 3700 Windungen |
| Mini 034-IG-75 | 80 Ohm ± 10% ca. 216,6 – 239,4 Ohm |
