Gear position sensor Part No

My GPS has been struggling to show a neutral light for a while now, and it's slowly getting worse I've cleaned it which helped a little, but it's still an issue.
This morning it started showing 2nd when I was in 1st, so I think it's time to replace it.

I think there is a new version of this that is hopefully more reliable(?)

Anyway I'm looking for the part no, it looks like the original part no is: 37730-01H01

But I think the one from the L2-L6 (37730-14J00) might be its replacement. Is this correct, Or do I need to stick with the original?

Cheers

37730-01H01 has been replaced by 37730-14J00. It might actually be hard to buy the OEM part from Suzuki nowadays.

Thumbs up Re: Gear position sensor Part No

So the newer 37730-14J00 from L2-L6 will fit K9-L1 bikes. I'll grab me one of those then.

Thanks a ton!

Re: Gear position sensor Part No

Do you plan to throw the old part out and, if so, do you have an ohmmeter? You could help the site if you'd be willing to do some disassembly. I can provide more details if you're willing.

Re: Gear position sensor Part No

Sure i'm pretty sure I have a multimeter of some sort laying around somewhere, although I can't claim to know how to use it properly! Let me know what you need and exactly what steps to perform and i'll see what I can do.

Re: Gear position sensor Part No

Here's how to take it apart, some of which is destructive.

1. Here's the sensor as it comes off the bike.

2. It's possible to remove or grind off the center pivot and remove the rotating contact holder. That's described here and gives you access to the contacts.



3. Here's the other side. There are resistors potted in (I think) white silicone rubber.


4. It's possible to remove the silicone revealing the resistors.

Gasoline causes silicone to swell/weaken, which makes removal easier.

5. At that point, the resistor resistances can be measured, which is what I'm interested in. The color bands can also be noted, though I've tried on those in the picture and the resolution isn't good enough to get values that make sense. It's also possible to measure things through the contacts on the other side but you need to know what you're doing there. The resistances are something like 370, 825, 1500, 2800, 6100, and 15000 ohms. The corresponding color bands for those resistances are Or-V-B-B, Gy-R-Gn-B, Br-Gn-B-Br, R-Gy-B-Br, Bl-Br-B-Br, and Br-Gn-B-R, where R=red, Or=orange, Gy=grey, Gn=green, Bl=blue, V=vilot, Gy=grey, Br=brown, and B=black. But that's mainly not what's in the picture. There will probably also be a fifth band that is Br and not of particular interest here.

Questions about gear position sensors keep coming up here and more information would benefit everyone.
