any experts on electrics and wiring loom out there??

[cookie81]

hi all, scoot is indian gp brought from rayspeed as one of their restored scoots 3 years ago. i havde recently purchsed a 120watt bgm stator as an upgrade from my indian one after having some problems with misfiring etc. but i now cant get a spark at all. i know nothing about electrics and am really struggling. i have checked all the usual checks that i have been advised ie plug, removed the green wire (ignition swithc) and also the green from the stor to see if i get a spark off this but still nothing. the flywheel fits on fine and no rubbing on pickup although i did notice that the inner boss did appear very close to the green wire going to the coil that meets with the white wire and am concerned it may rub!
someone has mentioned tipes and checking trigger points but i could do with this being explained a bit simpler and in more depth
the other thing is that i would like to get rid of the juction box and go from the stor straight into CDI however i already have wires connected to the CDI a green one( witch i belive is igntion swithc and i think a white one and the one on top i think is 2 wires joined together, i think one of them is purple and possibly striped and i think it is with a brown wire, in the juction box i have green, white, yellow and brown and into that i had prevsiously had the 4 wires from the stator although on my new stator i dont have a brown wire but a red one, also the brown and red are not a staright swop as the yello wire that was on the old stator was connected to the pikcup where this time it is the red one, so that has resulted in the yellow from the new stator having to go where the brown went from the olf one and the red wire going where the yellow went! confused? i have researched this on the net and cant even fined out which type of loom i have and which wires to joing together etc to get rid of the wire loom and take out the wires that i have in the cdi box so that i can put the stator wires straight into it! i may not have explained myslef very well, but if you can understand what im trying to say, any help would be greatly appreciated as i need to get this scoot back on the road as its my main mode of transport and currently having to use the mrs car, so shes walking and aint happy

try fitting the origional stator back ,this willeliminate the stator before you start messing all the wiring up,

i did think about that joe but ran out of time today, will try that next weekend before i do anything else. would be annoyed if it was that though, however i think the delaer i purchsed it from would be sort it out with little fuss as they have a good reputation, although if i did nt get any joy i know from looking at other threads the guy behind the BGM stators has sorted other problems previously and been very helpful,

i would oike to know though how to get rid of the junction box and also what and how to carry out this test with regards to tipex and trigger magnets etc

removed the green wire (ignition swithc) and also the green from the stor to see if i get a spark off this but still nothing.

The spark will be very small and yellow, you may need to try a few times to see it. If you haf a resistance meter it's possible to check the ignition side of the stator. The readings are in Sticky's book but from memory, the white wire is the stator earth and you should get a VERY low reading between it and earth, less than 1 ohm. Then test between the white and green which should read somewhere between 450 -550 ohms. Then white to red which is the pickup and should be around 95 - 110 ohms. If you don't have a meter then go and buy one, Maplin do a perfectly good one for around £10, it will pay for itself over and over

ive had good readings and its turned out to be the pickup even on genuine ducati items(vespa tho), now this could also be down to allignment issues from the trigger and pickup
as far as i know and understand the flywheel trigger fires when it leaves the pickup, sometimes its just a missmatch of parts that dont work well together

thanks fo replies i will look to get a meter then! can you get the maplin ones from any local stores like b & Q etc im on the isle of wight, so we dont have a wide range of tool shops!

I'm sure you'd get one in B&Q but it might be a bit more expensive. Alternately you could buy on line from Maplin, I bought one of these and it gets the job done http://www.maplin.co.uk/Module.aspx?ModuleNo=464984

nice one cheers coaster! someone else mentioned that it could be a miss match of parts with regards to the triggers linig up, is this likley with an indian flywheel, as ive seen a bgm leaflet on line that said it should be a straight swop for indian stator, and this bike had been running for the last 3 years.
one last thing, i have stickys book and will get a multi meter, however whilst i can do the tests outlined in the book as its easy to follw instructions i dont know how to test which wire connects to what, as i want to get rid of the junction bo but have various different colours so need to know what to do to find which wires need connecting to what

cheers mark

Good luck with sorting the loom out, I had a similar problem when I bought an 'Indicator' loom for my Jet thinking it would be easier than modifying the one that came with it.......I was SO wrong Sticky was kind enough to send me a pre production print of a servetta wiring diagram but what I had wasn't even close I ended up chopping away every thing I couldn't fathom and then added back the wires that I thought I'd need using clues from other wiring diagrams. Good luck

cheers coaster, thats filled me with optimism i will be looking at it on saturday and have saved all information i have found on a disc so will take lap top with me and hopefully will get it sorted. thanks again
