Workshop Manual Ed. 07-2012
Coil windings resistance inspection
Disconnect the connector (1) from the coil (2).
- Remove the coil (2) as described in the relevant paragraph.
- Measure primary and secondary winding resistance with a meter.
- Primary winding resistance: 0,09
±15% at 20°C.
- Secondary winding resistance: Open circuit.
If resistance is outside the specified limits, replace the coil.
- Terminal cap resistance: 5,7 K
±20% at 20°C.
If resistance is outside the specified limits, replace the cap.
Thermo-switch check
- Remove the thermo switch (1) and soak it in hot water.
- Using a tester make sure that when the temperature rises above 97±3°C,
the resistance between the two contacts is nil (short circuit).
- Make sure that when the temperature drops below 92±3°C the resistance
between the two contacts is infinite (open circuit).
- Switch-on temperature / electric fan start: 97 ±3°C.
- Switch-off temperature / electric fan stop: 92 ±3°C.
- Max load on contacts: Max 15A.
