TimR Posted January 5, 2020 Posted January 5, 2020 Im presuming based loosely on Has this got the correct coil fitted. Ie single wire ( Black and white wire connects and earth through body ) https://www.wemoto.com/bikes/honda/cg_125/77/picture/ignition_coilYou mention the bike has no ignition switch ...Has the wiring been 'hot wired' incorrectly ? Quote
TimR Posted January 5, 2020 Posted January 5, 2020 (edited) Black and white wire ...Where does this connect to on the coil ....As looks like it goes to the condenser ?And it should connect to the other wire if im not mistaken and condenser earth's on body .It should connect to connector Edited January 5, 2020 by TimR Quote
fastbob Posted January 5, 2020 Posted January 5, 2020 That's not right . Is the points back plate bolted down correctly ? Quote
Jetskiover Posted January 5, 2020 Posted January 5, 2020 The only wire connected to the ignition coil is the black/white from the generator. The coil is a single wire one and works correctly when wired to a 6v battery. The ignition switch is not connected. And all it does is short out the spark when switched off. So with out it the bike cannot be stopped if it started. Quote
Jetskiover Posted January 5, 2020 Posted January 5, 2020 Not noticed that until pointed out but will check. Am pretty sure I haven’t removed generator plate since losing spark !! Quote
Jetskiover Posted January 5, 2020 Posted January 5, 2020 Just checked and the backplate for the generator is in correctly its just the angle I took the photo at . Quote
fastbob Posted January 5, 2020 Posted January 5, 2020 (edited) Just checked and the backplate for the generator is in correctly its just the angle I took the photo at . No way is that the angle of the camera . That flat on the semi circular boss should be parallel with the top edge of the back plate . Like this . Hope you remembered the spring .

Jetskiover Posted January 5, 2020 Posted January 5, 2020 The black/white wire connects to the single wire which goes to the ignition coil but is also linked to the condenser. Quote
Jetskiover Posted January 5, 2020 Posted January 5, 2020 But the 3 countersunk holes control the position of the backplate ? Sorry thought you meant one side was not pulled in tight using screws. Quote
fastbob Posted January 5, 2020 Posted January 5, 2020 But the 3 countersunk holes control the position of the backplate ? Sorry thought you meant one side was not pulled in tight using screws. That's what I do mean . That back plate does not look like it's properly located in the crankcase . Like this . Quote
TimR Posted January 5, 2020 Posted January 5, 2020 To me that base plate is out by "180"Based on the image given by FBShowing lower section is filled Ie red dot should be where yellow is Quote
fastbob Posted January 5, 2020 Posted January 5, 2020 To me that base plate is out by "180"Based on the image given by FBShowing lower section is filled Polish_20200105_180110275~2.jpgIe red dot should be where yellow is F3A2CAE5-0A60-4C0F-94A9-A95DA734E5FE~2.jpeg Not possible , the screws are unevenly spaced so it cannot be wrong . Black and whiteite pic is early Japanese and colour pic is Brazilian . Quote

Black and whiteite pic is early Japanese and colour pic is Brazilian . I understand that but as you have pointed out there is something definitely amiss with that top location .If i was OP i would go back to start and redo ...Not noticed that until pointed out but will check. Am pretty sure I haven’t removed generator plate since losing spark !! So have you removed gen plate before losing spark? Quote

fastbob Posted January 5, 2020 Posted January 5, 2020 (edited) Remembered the spring ??? Yes the spring that stops the camshaft end float and is held in by the backplate. Edited January 5, 2020 by fastbob Quote
fastbob Posted January 5, 2020 Posted January 5, 2020 That backplate is all wrong . You're obviously not seeing what I'm seeing but it's not seated properly at the top . And one of the screws is totally f****d so I don't know what you are going to be able to do about it. I can draw you a picture if you want but it's all crooked . I'm surprised it hasn't cracked . Look how it sticks out at the top ! Quote
fastbob Posted January 5, 2020 Posted January 5, 2020 And it wouldn't surprise me if the bottom coil wasn't rubbing on the magnets on the rotor with the backplate at that angle ! PM me if you're still not understanding this . Quote
Jetskiover Posted January 5, 2020 Posted January 5, 2020 I am beginning to wonder if the output from the generator is incorrect even though it creates a strong blue spark. Quote
Jetskiover Posted January 5, 2020 Posted January 5, 2020 I think the spring is still in place. I can get all the screws out no problem as have removed a few times. Quote
fastbob Posted January 5, 2020 Posted January 5, 2020 I am beginning to wonder if the output from the generator is incorrect even though it creates a strong blue spark. And I'm beginning to wonder whether this bike is even 6 volt . That back plate looks like one off a Brazilian CG which I believe were 12 volt . Again , what year is this bike ? Quote
