Fault:
Mower does not start up:
Is Y4 (mower/fan on solenoid valve) energised?
Yes:
Measure coil resistance on Y4: should be 5.9 Ohm. If resistance is ok, check whether Y4 is mechanically jammed.
Solution
: Clean; replace if necessary.
No:
Complete following tests:
Test fuses F5, F19, F7, F15, F6, F22.
Test switches S1, B8 (seat contact) S5, S15, S22.
Test relays K1,K4, K6, K7, K9, K10. Check that B+ is applied at K2 on pins 1, 2, 3;
B- at pin 6. If the seat contact B8 is closed, B- must be connected at pin 4 via X 42 and B8. B+ must now be connected to K9:86
via pin 5. K9 closes.
