Ignition switch and charge light on LS

Hi Roy,
Its the yellow wire

John beat me to it.
Connect the five leads as follows (and study the wiring diagram): Black lead (Negative Earth) OR Red lead (Positive Earth) to Earth / frame / chassis Green lead to Field Yellow lead to Dynamo Brown lead to Ammeter White lead to Brown lead for 6 V operation White not connected (insulated) for 12 V operation

Good one GB, I've put it in my watch list, I'll need two 6v (XT500 & AG175) and two 12v (51 A7 & CB1100F). The only head scratch is with the A7 converted to 12v through a DVR2. 6v if it goes on the dynamo side or 12v if on the battery side.
Cheers

I am hopeless at electrics but, what has the magneto got to do with seeing if the dynamo is charging ?

They are unrelated.
My idea just uses a double pole switch that can control two different circuits. Before you could start the bike you'd have to click the switch to enable the magneto. At the same time the charge indicator would be powered.

 Fairly much the same as Rookie has done

 The Gizmo is a nice idea and I considered it, but with the cost of postage to Au added on, decided I'd see what I can bodge up ...

A) This will only show voltage when the engine/ dynamo is charging ??
B) It may flick on and off during daytime running ?? as the regulator switches on and off ?????
C) No switch needed LOL
John

A: That was the reason, as my ammeter was spinning.
B: Yes, at low speed, the LED will light up and also if there is too much current.
C: If there is no switch, the LED is always on when you shut down the engine.

Here the original and my new wiring diagramm again. Also the LED's
and the keyed switch (universal for Scooter or  Quad) with 2 contacts -1 opener (magneto) and 1 closer (dynamo), so you have 2 functions  with 1 turn.
Sourced via evil bay in China total cost: 5€

As I was going to sleep I realised my circuit has a problem. When the switch is closed the mag is earthed so engine is stopped, but, the charge indicator is powered! I need to arrange to short the mag but cut power to the LED. I'll draw a new circuit idea after breakfast.

Muskie seems interested; maybe you could share the UK to AU shipping cost. Any other forum members interested?

[muskrat]

I sent the vendor a ?. How much for 4 + post to AU. See what he says.

 yeah ta not really that fussed- I think I have it covered and can live without it, and would still need to add in extra leg and hassle of postage probably only a few$$, but see what vendor says anyway

 What I have done though, to alleviate the stress on lighting I've lashed out $90 on a LED headlight insert ($75+ $9 postage +$5 PPsurchrge ), supposedly draws 1.8A @6V 4-4.5K lumens....I'll keep yea posted on that- just waiting for it to arrive...

I like this idea, there is no way that you can forget to turn the LED off if you have to flick the switch to stop the engine and visa versa.
Now waiting for your revised diagram. After your Weetabix.

On my Ariel Square Four MKII I have a similar installation, but here also an oil pressure indicator ( red as very important and essential for a SQ4). The Ariel has an ignition switch by factory .

For my BSA I'm still searching a position for an oil pressure switch.

I made a start but a boring person asked me to go and buy skirting board!

OK, Roy, sorry if the word 'relay' fills you with dread but really it shouldn't. Here is my new improved schematic. When the, (now single pole) switch is 'Off' the relay is unpowered and the Normally Closed, (NC) contacts are earthing the magneto. When the switch is at 'On' the relay is powered, opening the NC contacts, enabling the mag. At the same time the charge indicator is powered. Any thoughts chaps?

Of course the switch could be a keyed one.

Suitable relays are not expensive:

Thanks GB. I know what a relay does and I can follow a simple wiring diagram, I just can't design one
