...but you need to be able to measure and machine to thousandths of an inch so the new contacts are press fit into the plastic before sealing them with an oil proof sealant

It will be done on a CNC mill... thousandths of an inch are not a problem...

Why a delay in the circuit?, you have a contact to use for neutral indication.

When the sensor gets milled for the other 6 pins, it will mill out the existing neutral pin.. and it will be easier to add a delay in the programming for neutral than try and re drill the neutral pin and solder to it...

OH, and if you need a test mule for your board .......... pick me !! I can get all the required electronics locally.

I'm considering building a second unit for test on another bike... if it comes to that.. no parts will be required, it will be complete out of the box... besides one chip needs to be programmed..

I'd be glad to volunteer as test dummy for an 1100...

A question for those of you that are interested in one of these units... would you want a shift counter? a feature that counts total number of shifts, then when accessed it will tell you how many shifts occurred by flashing the characters separated by a bar or the decimal point... once the it replays the total number of shifts it clears itself.

It's too late for this revision.. but I'm considering it for Rev B..

Thoughts...

Hey Jim, might want to start a thread just for that item

I've never had an issue with my bike, only being an 06 with around 10,000 miles on it, so I've never had to look at the safety switches. Does the Neutral safety switch rely on that neutral contact though? Just a question that stands out in my mind.

[GSXFJim]

thats all passed thru switches in the side stand and the clutch lever

[Unholy_m]

What would the shift counter be for? The total shift from the ride?

yes...

The neutral light relies on the neutral sensor and the ignition is disabled by the neutral sensor unless the sidestand is up.

... would you want a shift counter? ...

Wouldn't do anything for me.

[GSXFJim]

Wild... my pre had 2 ign interrupt switches.. one on the side stand and the second on the clutch post.. both are by-passed, my neutral sensor has never been hooked up.. and it starts up fine.. unless something changed on the post units.. that sensor provides a ground to light the light only...

[Wild-Bill]

I've got a pre. There's a diode in there that causes (or is supposed to cause) the ignition to shut off if the bike is in gear and the sidestand is down. The logic diagram is supposed to look like:
sidestand up OR in neutral => ignition enabled
sidestand down AND in gear => ignition disabled

[GSXFJim]

Interesting...

[ygolohcysp]

Okay, after getting home, I checked in the manual I printed up for my bike. My bike is a post, and this manual is for posts, but I would think the pre's are fairly similar. The neutral switch is indeed used in the safety system, described in the manual as the "side-stand/ignition interlock system". Basically, the neutral switch has two independent functions. One is the indicator light. The other is the side-stand relay. Each "function" is connected to the switch via a diode to prevent one function from effecting the other. The ground side of the coil from the side-stand relay has two different paths to ground, the neutral switch and the side-stand switch. That way, if the bike is in neutral, the coil works and the ignition can then make it to the kill switch on the right handle bar. OR if the side stand is up, then the coil works, and the ignition can make it to the kill switch. This also works with "AND", of course.

Here's the really really bad, hurt-your-eyes pic from my phone, of the manual. I don't presently have the time to find my scanner, and a usb cable, and scan it.




Sorry for the bad quality.

[GSXFJim]

I did the same.. I printed out the pre schematic and traced it out.. seems that my kat has been fooled with prior to my taking possession of it.. my neutral sensor has never been hooked up... I have a feeling that the NP sensor circuit is grounded somewhere to fool the side-stand diode into thinking its in neutral all the time allowing the bike to start normally.

So with that said, YES.. a GS sensor will be needed to keep the Kat's side-stand/ignition interlock system functioning as designed, unless it is bypassed.

The programming of the electronics will still have the Delay built in to display the 'n' character when in the Neutral position. If you choose not to by pass the side-stand/ignition interlock you will still have your green Neutral light in your dash...

I'll have to do some looking to refresh my memory on the exact nature of the fact that on the post Kats, the neutral sensor also tells the ignition whether the bike is in 1st gear (or is it second) I'll get my manual out in the morning and check.
