I need some help here. My bike has started to run for a bit then just stop. Easy to start, runs for a bit, then stops. I put a scope on it to see what sort of signal it is getting for Crank Input VR1 at the Arduino Megga's pin 19.
The scope is set to 20V/ div. and the signal looks pretty much like the raw signal from the trigger pickup. I just need someone to confirm I am on the right track thinking that the the VR conditioner board has failed as the signal at pin 19 should be 0-5V.
Vido clip attached of the bike idling at 2000 rpm. The rpm in Tuning Studio jumps about the place a bit. The oscilloscope trace of the crank 24-1 trigger signal is towards the end. Is the VR conditioner limited to an input of 12V max, or should it be able to handle 50 - 60V Ok?
