Re: Skoda 1.4 tdi crank sensor

Re: motorbike ignition fault

Not sure I understand the underlined part ? I think I possibly misunderstood your question and was remarking on the entire ignition event. But possibly where the clamp is in relation to fault will yield different results. For example the rotor notch on the coil lead but not the plug lead. Although ...
