Reducing 20v ac to 6v ac

Well done, you got the result!

Hi
Can you tell me what this component does please? Its not wired into the generator system and its missing from the stator on my bike...I believe that is the problem
Thanks

It was probably a coil for charging the battery.

No battery on the bike, this is standard for this bike

Yes, which is why it doesn't need the extra coil.

I fitted the ac voltage regulator but it still popped the bulb...confused dot com

Are you sure you wired it correctly, did you measure the voltage at the lamp.


AC regulators connect to the generator winding so that excess voltage can be dumped to prevent bulbs blowing.

When fitting an AC regulator simply connect the yellow wire to the feed from the generator and earth the case.

The regulator case must have a good earth directly to the generator. Where there are two
wires from the loom, one will be earth, the other will connect to the regulator’s yellow. You’ll need a multimeter to check which is which or the wiring digram.

AC systems require the earth to be as good as the feed wire. Relying on the engine mounts is not good.
Where problems persist adding an earth wire to the regulator mounting bolt, direct to the engine case can help.
Poor earthing is the most common cause of problems.
