An electronic pick-up, as opposed to a points ignition works without contact erosion and are therefore virtually maintenance free. The pick-up is not mechanically attached, but instead, as it is in effect in combination with the permanent magnets located in the flywheel a small generator, produces a small electrical impulse, so controlling the ignition spark timing. This makes this variety of ignition not only very reliable, but also capable of sustained high revolutions of far more than 10000rpm. Most of our pick-ups are OE PIAGGIO items.
Conclusion: The pick-up is the most fallible part of your stator plate assembly and therefore should not be missing as part of your backup parts for any long journey on your scoot.
SIP-TIP: Most pick-ups function at an internal resistance of 115ohm. If while checking this is not so, then it needs replacing.
