hey ,
This is quite an old thread but i really want to do this to my RXS can someone tell me if the same priciple applies . I.e. can i follow the guide and use the C90 cub rec/reg ?
Thanks
Dave

I would de wire it and then re wire it one at a time to see where the fault lies , Its definatley shorting somewhere although why its coming back to life when you touch the neg terminal is beyond me . Thats a weird one for sure.

when I was buying new coils I came across those. Figured that there was no satisfactory way to use them as you need a + supply for the coil and an interupted earth for the points.
the only way to use them would be to isolate the coil form the frame and run a negative to the points, not the best.
check the ohms rating as they could also be for electronic ignition systems!
Thats kinda what i thought . Mine is electronic which would suggest thats why mine has only one wire also . (mine is poxy 6v too ....yamaha definatley mucked that one up !!)

It's ok, at least your offering advice! I just cant think of a logical way around using a coil with only one hook-up without using more relays (which I certainly wont be)
i would try and source some better coils in that case .
-
A coils ground is the spark plug though isnt it? My old coils has two wires in, one for the condensor and one for the points.
yeah you`re probably right . See i told you i would be completely wrong ..lol .
looking at the coil though . Its a metal chassi and if its a neg ground it will be grounded by the frame . Thats where my assumption came from .
it might be an idea to get the coils with 2 wires to make sure you`re ok
-
yeah that will be grounded to the bike . So if your bike has the black cable from the battery connected directly to the frame you should be ok . If not you will need to run a negetive to the chassi part of the coil .
IMPORTANT EDIT : IF YOU TAKE THE SECOND OPTION I WOULD ADVISE THAT YOU SHIELD THE COIL FROM THE FRAME WITH RUBBER OR THE LIKE OR YOUWILL INADVERTENTLY ADD A NEGETIVE GROUND TO THE BIKE REMEMBER TO DO BOTH BOLT HEADS ALSO FOR THE SAME REASON. YOU DONT WANT ANY PART OF THE COIL TOUCHING THE BIKE INCLUDING BOLT TO COIL TO BIKE ....IF YOU GET ME
My rxs has a neg ground so EVERYTHING only has one wire ...lights , coils ,everything . This can lead to ground failure and it can be a pain to find if somthing corodes etc . so if you are designing a newsystem for it it may be beneficial to you to put in a negetive rail .
sorry fgor all the edits ...haha ... : if you redesign a bike from neg ground to a "railed negetive" you will need to isolate everything from the bike . I dont even know if that is possible so definatley ask somone with more knowledge than me !!

You GOT a score of 6 out of 11
well its over half i guess . Still dont get how 30 divided by 1/2 is 60 ...lol.
guess 30 times a 1/2 is 15 isnt it ...mmmmmm

Normally if theres only one wire going into somthing it means it needs a negetive ground to the frame.
That is only a guess as i dont know the bike. So i`m prob worng.lol

The prob you are having is pretty normal for a rxs . I have the same issue with mine all the time . The electrical system on them are rubbish. I`m looking into converting mine to 12v as i`m so fed up with having to recharge the battery all the time and having the indicators dull all the time . just replace your flasher and make sure the battery is fully charged and check all the earth points . When you have had enough of doing that look in to conversion !
