Just fixed it.
Turns out the green wire from the field coil goes to the middle bottom on the 9 way connector.
But the mating half of the 9 way connector has the corresponding green wire fitted in the middle top.

Moved it back to where it should be and its all working.

Hopefully that is the last electrical bodge on this bike  :o

Is there 12V across the coil.  ie. 0V one side, 12V the other. 

12V on one side only tells half the story.   If there's 12V across the coil and if it isn't open circuit,  then it should turn into a magnet,  which should then induce an alternating current in the field coils because of the wriggly iron thing bolted to the crankshaft spinning round.  Getting too technical now.   :)

Thanks Mike, i'll double check tomorrow.

There is 12V on the field coil, I measured the white wire that feeds it, the 12V is good.

The field coil appears good as the resistance of it checks out and its also not shorted to ground.

Have replaced the rectifier and regulator as the wiring was burnt out to the rectifier. Have replaced them with the combined solid state unit.

The field coil measures 5 ohms which looks correct and there is battery volts on the white wire to the field coil.

The three yellow wires from the stator measure about 1.0 ohm each which im guessing is correct if you take into account the resistance in the leads of my multimeter. Each of the 3 yellow wires also measure opent circuit to ground.

When the bike idles, im getting around 0.65 volts ac across any 2 yellow wires which is nowhere near enough.

Any ideas? im guessing the stator coil is fried but there is no evidence of any damage to it.

Check the fuel tap, I had fuel only coming out of one output.

Stripped it down, but couldn't see what was causing it. As it was leaking anyway I replaced it and was fine after.

Thanks SteveW,

Appreciate the help think you got lucky with £54 as the one I see on M&P is about £87 :(

Cheers
Topcat

I don't believe it, I only bought it 10 days ago £54.99 all in. Just checked and you're right, they've whacked it up to £87.  :o

Just checked, I ordered it 6th Nov

I fix MRI scanners in both the NHS and private hospitals.

Due to the very powerful magnetic field i have a set of tools made from titanium, very, very expensive.
If you take anything metal into the room of any size, it will stick to the magnet and you wont get it off.

Not sure about the anti gravity batteries but i've just bought the Electrosport ESR240 regulator / rectifier and hopefully fitting it this weekend.

Bit of a tech review here:

Cheapest place i found for it was £54 from M&P with free delivery and came in a couple of days.

This is why i'm replacing mine, circled in red :(

Finally sorted the wiring so that all lights and switches work as they should  :)
Also the tail light now comes on when the ignition is in the 3rd position.

Just got to replace the rectifier and regulator, i assume the rectfifer is toast as the cables to it are melted.

The wiring loom will be replaced next year, I'm trying to get it ready for an MOT at present.

Thanks, very much for the reply.

In the fully clockwise position it does nothing at the moment, the wiring has been very badly bodged.
