    Would it be possible to run a battery with this setup ie connect the positive battery terminal to the red output? Useful for the sip speedo when the scooter is not running and to power lights properly at low tick over…?

      Yes, this will run/charge a battery which is fine if you already have a battery wiring system on the scooter. The most important thing is to make sure you have a battery ignition switch and wiring so that the battery is isolated when the ignition is switched off so it can’t drain while the engine isn’t running.

    You mention the problem with vespa indicators. LED relay and bobs would cure that quickly enough, wouldn’t it? Similarly (from memory, I’d need to do a switch to check) a DC model horn switch, with wiring that runs to earth after the horn, would be a possible solution there. Can’t see any reason why not, but it would need testing.

      Not sure an AC Vespa indicator relay will work on DC, LED bulbs and resistors to stop them flashing at the wrong speed is a.different issue.

    Whats to be expected if this conversion fails? No lights and then a need to replace a lighting coil? Or will it transfer to the ignition side as well?

      It is a totally separate circuit to the ignition (still) so the engine wouldn’t necessarily stop running if the lighting circuit suffered a problem.

    I did something similar to my lambretta but kept loosing enough power at tick over to power sat nav which is when you normally need it most at junctions and roundabouts,I found this very frustrating.Went for the battery option in the end,trickle charged from the engine,much better for sat nav use with no loss of power.

    Replicated the above, but why does the headlight glow fractionally brighter as i rev? voltage at and above 2k rpm is 14- 14.5 v max at the battery. voltage at the headlight socket reaches 14 on revving.

    I have a stator with four poles, two 30W with one yellow and one green=earth.
    Ignition coil which is grey goes to CDI
    The last one is grey and not in use at the moment.

    I understand that I can’t use three but could I float the two 30W coils? I plan on using a reg/rec with a battery.

    Has anyone actually converted a PX with both AC and DC to fully DC ?
    If you have, how did you do it ?
