Wired up the gauges & my gear indicator today. Left the N off the gear indicator & wired to the new gauges instead, I think it looks better that way.
The gauges are reading ok but I had to do a couple of things.
1. Set the RPM to 4 stroke, 2 Piston (presumably as it's wasted spark it's sparking twice as much as a 4 stroke would normally spark).
2. Problems with the indicators. They do not light or flash properly even though I have an electric relay already installed. Flashers installed are LED on this bike which could be a factor. If I plug the original gauge set back in then they work fine so I am guessing the fix is to insert a resistor into the wire between harness & gauge. Original bulbs are 12v / 3w so I worked that back to a resistance of 48ohms. I'm not even sure one that low exists (or if it would matter if a used a higher value resistor) & also unsure which way to face it, band towards loom or band towards gauges. Can someone help me out??
P=IV 3 = I x 12 = 0.25a
V=IR 12=0.25 x R =48ohms
3. The water temp connection (Purple) appears to be for a light on the dash only (or maybe it's also for one of their senders. The Suzuki wire (Pink) has no effect on it & the temp light (red) stays on the whole time. - I cut the connection & it has now gone out.
I'm now thinking I have to use the other accessory to get an oil temp but the Suzuki temp sensor is very low resistance (100 ohm) & I measured the one that came with the Koso kit & at room temp it is 11k ohm or there abouts. It also has two connections rather than the Suzuki single connection. I may just leave it disconnected for now. The annoying thing is that oil temp & fuel are twinned on the left of the gauge & water temp & clock are twinned at the top. I can't get clock & fuel level to show together so it always leaves one annoyingly blank or flashing!
4. I connected the side stand switch to the Hazard lamp in the idea it would work backwards (i.e. on when side stand is up) but it doesn't work at all. I could probably connect it to the Water Temp Light though & it should work properly - I have to think about that!!
High Beam lamp works fine, fuel gauge works fine, Tach works fine. Not connected the Speed sensor yet as their bracket isn't long enough for the sensor to line up with the magnets in the bolts. I have to fabricate an extension (using the 2nd sensor bracket they included I think or a bent piece of thick Aluminium stock should do it).
I should get the speed sensor mounted next week & by that time my seat will be back from Sargents & I can ride it!

Engine is not running in the pics. Tach is only digital (numbers) which is a bit of a pain... thinking the Acewells might be better from that point of view.
