I purchased the Koso TNT-01 meter and everything is wired up and functioning properly except the tachometer. The attached instructions show that there are multiple ways to cable the tach wire. In talking with Koso tech support they said to attach the tach wire directly to the positive wire coming off of the ignition coil. I have tried both the brown wire and the orange wire shown in the attached picture of the coil but it doesn't seem to work. The attached also shows how I currently have it wired which is to wrap around the plug wire. This method works pretty well and there is only a little bit of tach chatter. the response to the throttle is also pretty good. I feel like this could be rock steady with the proper wiring and would prefer to hard wire it.
Does anyone have any idea of which wire (positive side of coil) I should be using? Or have any other ideas?
Any help would be greatly appreciated.
