No spark!

@declan so to rule out a few things, will the dt start without the ignition barrel,will the neutral circuit cause problems if the wire is not looped, would the clutch circuits also cause problems if it’s not looped

I found these wires wrapped up two of them are joined together I can’t remember if there were other joined like this, they come from the same loom as the battery wires

[declan]

Okay, looks like the problem is the ignition coil when I remove the wire and kick the bike it shocks me yet when I connect it back up the plug still doesn’t spark I already have one on order so I’ll update when I’ve fitted it...(edit- by remove the wire I mean the direct feed from the cdi to the ignition

[NINJA]

@declan Are there any breaks in the wire, which could be causing a short circuit???

[declan]

@NINJA nope, just seems the coil went dead

[NINJA]

@declan OK well hopefully a new coil will resolve the issue???

[declan]

@NINJA it should do

[declan]

@NINJA never that simple is it I have power before the coil but when connected up I get nothing

[NINJA]

@declan Are you sure that the correct wires are connected to the right terminals bud???

[declan]

@NINJA yeah just as the original was, it will shock me every time but the second that power wire touches the ht terminal the power vanishes

[NINJA]

@declan It sounds like you have a short somewhere else? Re-check all the wires as something is a miss.

[declan]

@NINJA I can’t find anything wrong it doesent make any sense I could understand if it was weak power but no power at all is flowing through

[NINJA]

@declan Well something is causing the issue, try using a volt meter to check volt's & Amps etc

[declan]

@NINJA how do I go about testing things I have my multimeter now

[NINJA]

@declan Look in the Haynes/Owners manual there should be a list of voltages. You then just put one probe one each wire and check your readings against the ones listed.

[declan]

@NINJA hi, I have looked but I’m not familiar with wiring in general I don’t know which ones I’m supposed to be testing

[NINJA]

@declan The ones to the coil would be the first place I would look. Then check any other wires associated with the ignition system. I suspect that you have something either not connected correctly or an earth is failing? Scrape some paint off underneath the ground eyelets to ensure that you have a good earth, as a bad earth will cause a short circuit and give you problems.

[oldman]

From experience the earths are prone to fail on old looms, check continuity using your multimeter from various places. Have you unwrapped the loom around coil area? Definitely worth checking, look through my red bike posts and you will see I had to renew earth from that area. Earth cable oxidised internally and started intermittently failing and quickly failed altogether .

[declan]

@oldman I figure it has to be the stator because when I hold the power wires coming from the stator I get a decent shock but when I do the same but on my 50cc the jolt is easily 4or 5 times more powerful

@declan Dude you've gotta stop trying to electrocute yourself!!! :grinning_face_with_smiling_eyes: :smiling_face_with_open_mouth_closed_eyes: :smiling_face_with_open_mouth_cold_sweat: :face_with_tears_of_joy:
