Ignition Coils, P/U Coils, Tach Signal???
I've got the jumpy/intermittant tach Blues. Seems like I read on a post that a similar problem was cured by cleaning and re-seating the connectors. Trying to find where to look for and check any connector/connection probs. I'm confused as to which coil provides the tach signal. I see the pick-up coil on the Ayers fiche. Looks like it has 1 input connector and 2 output connectors but I'm having a time visualizing where these are on the bike or if this is where I should even be looking. Appreciate any tips or feedback. Right now, I sometimes get what looks like a good reading when I first start up but as soon as I give it throttle it drops off and then begins jumping. Some jumps seem to go with road bumps. Then, as it warms up, it often will start reading but at approx. 2x what's expected (9500~10K @70mph). If I decel it will drop off and go back to jumping. The bike runs great other than this.
