600 F - starter motor will run with bike in gear. Fault ?

[QuadClown]

The other day I by coincidence found out that my 1996 600 F will turn the starter motor if the start button if pushed even if the bike is in gear.

All other bikes I've ever owned (all Yamaha's btw) could not start if the bike was in gear .. unless the clutch was pulled.

There's no clutch lever switch to be seen, and a wiring diagram does not seem to show any kind of clutch switch located anywhere else (for the 1996-97 models, pre ´96 wiring diagrams does show a clutch lever switch. Diagrams for the 98+ also show a clutch switch).

So .. it seems as the '96 does not have a mechanism to prevent the starter motor from being activated while the bike is in gear which on the other hand does not sound right to me.

Could someone please enlighten me ?

I beleive someone has modified the bike on you.
The wiring safety interlock system has not changed fundamentally between the 88 and 06 models.

Sensors:
Clutch sensor
Transmission neutral sensor
sidestand sensor
run-switch

Neutral + Clutch: ignore sidestand switch, permit start, run
Neutral - Clutch: avoid starting, but permit running
Gear + Clutch + Sidestand up: start, run
Gear + Clutch + Sidestand down: no start, no run

Good luck tracking down the changes in the wiring from stock.

I can let you know where the wires from the clutch lever go if you can get them in there
