How do i diagnose a faulty neutral switch?? light doesn't come on... but starts with clutch in and kick stand up... shuts off when kick stand goes down while running in neutral...
The neutral switch is lockated at the left side of the engine. Should have a blue wire... Comes together with a black wire ( oil pressure switch ) in a 2-position connector to the main harness.
Try if works fine with the blue wire at the ground and loose. If then everything is OK, the neutral switch is out of use.
There is also a diode set in the circuitry. With a green wire coming from the side stand switch, the blue wire from the neutral switch and a lightblue wire going to the dashboard. +12V on this light blue wire should lit up neutral lamp at the dashboard.
Hope it helps.
1996 SUZUKI 750 KATANA ENGINE RUN FINE BUT DIED WHEN PUT INTO ANY GEAR THE BLUE WIRE COMING THE TRANSMISSION/FRT SPROCET GROUND THE WIRE HARNEES SIDE OF HARNESS TO EARTH/GROUND ,THIS IS ONLY NEEDED IF YOU HAVE BYPASED ALL OTHER INHIBITORS,YOUR NEUTRAL LITE WILL THEN REMAIN ON AT ALL TIMES TAKE OUT THE BULB OR DEAL WITH IT.
Hi and welcome to FixYa,
A way to test the neutral switch is to check its continuity to ground. At neutral, it should read as 0 ohms. Additionally, Suzuki uses a dual diode to interlink the clutch and neutral safety inlocks. If the neutral switch checks out, this dual diode may have to be checked likewise.
Good luck and thank you for asking FixYa.

WHEN I go to find these wires, will there be other wires in the area of the side stand and those going to the diode you are referencing?
I'm not near the bike at the moment and not 100% familiar with everything on the bike due to no manuals... So I am trying to get a mental image of what I am going to see when I go to check the switch (need location), and where the Dual Diode will be at as well in reference to other parts on the biks. Can you give me more details or have a diagram (can't find any online for the bike free)
Where at on the left side of the engine is this located at? I am not near the bike and dont have any diagrams to reference this to get a mental image. I am trying to have all the facts and info so I can fix this in the morning and not have to come back in and send more questions.
SO, is this switch near the left side near the seat? Down near the side stand???
Next, explain what you mean if the bluw wire works at the ground and loose? are you telling me to move the wire to a different spot and than to unconnect it?
And than the dual diode in the main harness... Where would i find the wires going to the diode at? NExt are you telling me to take a wire from the positive terminal of the battery and connect the other end to the light blue wire? By doing that it will light up the neutral light is what you are telling me correct?
I'm not that smart with wiring or troubleshooting electrical at all. I appologize for being a pain but your help is much appreciated and I am grateful for the help I have received so far!! Thank you
