Honda Hornet 1999 kill switch circuit current

[steven_191]

Had a look at the wiring diagram and it seems the kill switch circuit is fed from the 10A starter circuit. This in turn goes to the coils and/or the ignition control module.

I know that the 10A part doesnt sound right going to a control module, but thats what the diagram says. Im guessing its a low current circuit but im after putting an opto-isolator in line for part of a project. I just need to ask (bit of a longshot), but does anyone know what sort of current is going through that circuit? at least, the kill switch part.

Im hoping not a lot.

You could always get your multimeter out and ask that?

CBA to take my kill switch apart and tell you... but have you tried asking on the hornet's nest? Probably better to ask there as there's so much hornet-specific knowledge.

I havent looked into it on the bike yet so just thought someone might already have had a play with this sort of thing and might have a clue. Im guessing the circuit has its own fuse to which as a limiting factor makes it easier to pick the part i want.

Just found another diagram more detailed of the ignition. It seems it is a 10A fuse to the kill switch and then onto the coils and module.

by the looks of it I may be able to switch the neutral in parallel to the side stand safety circuit. This should be the cable that cuts the ignition when you have the stand down and try to put it in gear. This should be minimal to no current by the looks of things.

this is for an ignition kill by the way to cut the spark. I dont want to interrupt the part of the circuit covered by a 10A fuse if I can help it.

You will usually find a diode pack in there somewhere that links the neutral, clutch lever and sidestand switch in a magical way so you can't do anything silly.

Is there any particular reason you are trying to tamper with it?

yeah i see the diodes on the wiring diagram. It doesnt look as though it will cause me any problems in terms of bypassing because its still following the same route.

Im playing around with a quickshifter and want to find the best means of cutting the spark. Cutting the feed to the coils via a 10A circuit isnt the way i want to do it but it does split off from this feed into the ignition module. This may just be a feed to run the control board in which case it will be on a much lower fuse rating. So I could cut it here and that may stop it switching the coils. This feed is run directly from the kill switch. I may have to open the module to see where the feed goes. The only problem i see with the clutch/stand safety circuit is that when its in neutral the ignition will run as normal so changing from first to second may cause the ignition to start up mid shift.

I think my best bet at the minute is the feed to the module but without looking closer I cant say for sure yet.
