I love the Acewell Gauge and am more than happy with it. Mine's been in use for over a year. One thing I've found is that the angle must be proper to read it in dark conditions. I don't think it would be readable laying flat in a headlight nacelle. (?)
Yeah, That's been my experience with the wrap too. That and instruments blanking out at higher RPMs (my timing light for example). I was wondering about tapping into the wire from the points near the coil, or off the dyna booster, now it's all coming together.
Thanks, good replies here from you guys.
