Hi all,

Now we have rectifier/regulators we can dump all the complex mixture of direct ac lighting and dc battery charging.

On my D7 i have wired all the alternator coils together in parallel with no earth. Now with only 2 wires from all

the coils they can be wired to the input of the rec/reg. The output dc can be wired to a battery and then

to the lighting switch, instead of a battery I use a capacitor.

I find the lights are heaps bright enough even at very low revs and as i only ride the bike now and then

there are no more flat battery issues.

If anyone is interested i will post the capacitor values.

Nothing like a Bantam to stop you thinking about the real world.

Cheers, Nick

Hi Nick, nice work mate and a very attractive idea to get around all the head scratching and confusion.

When you say you have joined all the wires together with no earth but then 'with only two wires from all the coils' - please explain -    is one of these wires the earth ??

Sorry to be a bit of a thikko

6 wires from three coils all wired in paralllel = 2 connections. All the starts form one wire all the ends form another.

Four now on the road and at least several in bits.

Hi, yes please, I would be interested in the capacitor spec. Also as you have only 2 wires from the coils are you running an external ignition coil?

I'm in the process of re wiring my D7 to battery and external coil and using a capacitor rather than a battery would suit me better as I also only use it now and again (warm dry days).

Hi all,

Put the word,  compass into search and click on posts from neddyo,

ADMIN EDIT:- ** Please log in to view **

one has images of the coils and using a compass to find the polarity

of each stator pole (the part that the coil is mounted on) 

To power the coils you can solder leads onto any torch battery,

aa is ok.

The capacitor values are in there somewhere.

It is important that the coils are hooked up to read

alternately n - s - n  or  s - n - s.

I will take a photo of how i mounted things on my D7.

The good thing is the ignition system is quite seperate.

Cheers, Nick

Hi Bean,

You will need a battery if you run a coil other than the stator mounted one.

The generator output at kick start revs is probably not enough although

I have not tried this, I will give it a go.

Hi Nick,

Thanks for the info. Have had to go for an external coil as I think I may have lost a few gausses from the magnets over time as it takes some kind of effort to produce a spark. I'm not convinced the kick start mechanism should take so much abuse (or me). With a battery and external coil a spark is available by  a gentle kick or by hand with the plug out. No brainer really for my bike. Not got round to checking output from the other coils yet with it running. I will get a capacitor and try that too.

Thanks again,

Rich (Bean)

Here is a module I made for a D1, although it would

suit any D1 to D7.

The bracket is aluminium onto which is bolted the Rec/Reg,

on the other side using the same bolts is a square of 3/16 PVC.

The capacitor is glued to this with silicon together with the connection terminals.

On the stator the blue and brown wires go to the ac wires on the reg. which are pink and yellow,

the red link joining the terminals on the stator has been removed, also the white wire has

been removed.

The other side shows the green wire from the DC side of the reg. going to the left side terminal

and from there the green and yellow wire to earth in the head light also the negative wire from

the capacitor. This reg. mounting bolt also goes to earth via the aluminium bracket.

The centre connection is not earthed and shows the red plus wire from the reg. with 2 red wires

going to the head light switch and the stop light switch.

The 6 volt rec/reg I got from Paul Goff although also but not easy to find on the internet.

(does that last sentence make sense)

The 3 lighting coils are wired in parallel hence only a 2 wire output.

That's a very neat installation.

I forgot to mention, this is a good chance to convert

to 12volt.

Instead of the 6V reg. use a 12V one and of course change

the bulbs etc. The capacitor should still be happy.
