I think what follows may be more useful than my modifications to the wiring doiagram above.
Cox 09M7 wiring circuits
A = Alternator
B = Battery
M = Magneto
S = Solenoid (for starter)
1. Ignition off – shorts out M and G (magneto and ground)
2. Ignition on – opens M and G, power to L for lights (not fitted)
3. Ign Start position – circuit for starter motor. Cutter handle back
– Power from B to S
– S to cutter switch No 1
– cutter switch No 1 to Foot switch
– Foot switch to solenoid
– Solenoid then sends power to starter.
4. When cutter handle back – ie cutter disengaged, 2 microswitches in one switch. Starter circuit closed (cutter sw 1) , magneto cut sw 2 open. Means can start with bum off seat. As there are 2 switches in series (seat and cutter) and both need to be closed to cut (ie earth) magneto.
5. When cutter handle forward, cutter sw 2 closed, seat circuit closed ( so when get off seat, sw closes and shorts out magneto circuit) and start circuit open, so cant engage starter when cutter engaged.
6. other safety circuit – stops mower if cutter engaged and bum off seat

Wires and circuits
7. wires to components
7.1 foot switch
(a) red/pale blue (to solenoid)
(b) dark blue-white – cutter switch
7.2 Seat Switch
(a) Green in (from cutter switch 2)
(b) White out (earthed)
7.3 Cutter Switch 1
(a) Green – magneto
(b) Green – seat switch
7.4 Cutter Switch 2
(a) dark blue-white (from foot switch)
(b) blue – ignition
7.5 Solenoid
(a) separate pin connector red/pale blue (to foot switch) – this is the activation wire for the main solenoid switch
(b) main terminals
(i) Top terminal – heavy red wire to starter
(ii) Bottom terminal –
(A) red to fuse to ignition B
(B) red to plug beside engine which becomes 2 wires
(C) heavy red from battery
8. Circuits through safety switches
8.1 starter circuit (activates solenoid). This can only be activated with cutter handle up (cutter switch 1) and foot switch depressed. These are normally open and when both are closed starter can be energised.
(a) Ignition S (blue) to cutter switch 1
(b) Cutter switch 1 (dark blue/white) to foot switch
(c) Foot switch (red/pale blue) to separate pin on solenoid, activates starter switch
8.2 Magneto short out circuit – this circuit is completed when rider is off seat with cutter engaged. With cutter engaged Cutter switch 2 is closed but with rider on, seat switch (normally closed) is open. Getting off seat closes circuit to earth.
(a) Magneto to Cutter Switch 2 (green)
(b) Cutter switch 2 to seat switch (green)
