Help please.

I think i got this figured out but can someone please review it.
Bought a new motor and loom for a go kart project but cant make a lot of sense of the full loom.
Going to rewire it and have got this far.Wanting someone to check it before i start hacking up the original.

Thanks in advance

 

Yes, provided that CDI is a DC one and that the pin out is as you show it, different CDIs have different pin outs. 6pin seem to have two positive feeds on many wiring diagrams. I try to keep it simple and use a 4pin CDI for DC systems, or go Kawasaki KLF300 which uses an 1990s car system.

 

Thanks Merryman.
Im assuming it is a 12volt as there seems to be no link from the magneto back other than to the regulator. If I'm wrong and power it with 12v DC will that harm it? Also is cutting the 12v feed enough to stop the engine? I've assumed it is although it does look like the loom has also meant to have a kill switch in the blue/white (I'm picking this is the spark timing). Also should the feed from the regulator come back in on the loom side or battery side of the fuse?
thanks for the help.

 

Yes you could harm an AC CDI by shoving battery power through it, but it isn't going to work anyway. Kill on the Blue/White is unusual though not unheard of. Some Hondas use one of the yellow alternator wires to power a sort of AC/DC hybrid CDI so no extra "power coil wire" but still AC powered. Sorry I had missed the regulator mistake in your drawing. The main fuse should be on battery side of regulator. Most common reason for fuse to blow is regulator failure.

 

Thanks for the help.
Update that I did the wiring as per the picture and engine started first pop so all good.
Only issue I have is that the led I have didn't work as per it should so when I was wired through it it wouldn't work in either lighting up on power or completing the circuit. I'm a bit lost as it was purchased new🤔.
I'm going to have another look at it tomorrow and see if I can figure it out.

 

You are putting all the ignition circuit's power through the LED. I'm not up to speed with LEDs but if it was an incandescent bulb, that wouldn't work. Bulb teed off with other side of it direct to earth, is correct.

 

Yip that's what I ended up with when I rethought it as well. Now all done. Thanks
