I am having trouble diagnosing my 1977 t140v ignition. The coils seem ok I checked the power to the switch leads and have power from the brown/ blue wire to the white wire but not from the blue/brown to the brown/white wire. I don’t know where to go from there. Any help would be greatly appreciated. Thanks.
The symptoms would probably help with the diagnosis mate....do you have or have you downloaded a manual?
What is your issue, you are diagnosing because the bike wont start? you turn the ignition on and what happens, does the ignition light come on? have you a spark? give us a bit more rope mate and we can try and help
Thanks for the reply I was riding and the bike backfired and quit.(had to get it towed home) Fuel is ok Lights horn etc ok No spark. Coil primary and secondary seem ok. It has electronic ignition. Cheers
I will have to l Check this out. I posted a pic of the switch power from blue/brown to white And nothing from other leads
Eric27 My 77 was positive earth. And I think the blue and brown was disconnected on my bike believe it was for the kill switch. But this is just guessing. Regards Joe
