cg 125 toughy!!

[andwat16]

got a cg 125 m1 and it has been sitting in front for about a month, i went to start it and it wouldnt.....so i changed battery and spark plug tried again and nothing, i tested the spark by putting it on cyclinder head and there was no spark (not even on old plug) i have noticed aswel that the headlamp doesnt come on when switched on, nor does the tail light with lights switched on (but does come on when brake is applied)

i have followed the wires from ht lead and everything looks ok, no cracks or splits so im abit baffled

i also checked all the light bults too

any ideas why the headlamp wont come on, and is this a result into why it wong even spark? wont even spark on kickstart either

cheers

So you're absolutely sure the battery is charged and yet the power is completely out? I'd try to jump start it from another vehicle just to be completely sure but otherwise it would sound at first like an electrical / wiring problem?

What year is the bike?

ms51ves3: why does it need 500 miles? Are you teaching it how to be a piston?

[andwat16]

its 2002 model, with both kick start and electric start

brand new battery fitted, indicators work fine and rear brake light, but not rear tail light if that makes sense?lol

Is there a fuse somewhere that might be broken.

[andwat16]

there is one fuse on the bike, and that is straight from the battery, so if that has blown nothing electrically will work

[Alexio]

Ah I see. Does the starter motor work then?

If what you're saying is that some of your lights DO work but you have no front light, rear tail light or spark then it's more likely a wiring fault. I don't know much at all about the wiring / electricals of a CG to be honest but there might be a fuse somewhere, the bulbs might simply be blown, there could be short circuiting or corrosion even.

All this is just a guess though, there are still plenty of other things it could be but it's worth checking as much as you can. Were it me I'd have someone look at it or get someone to help me follow as much of the wiring as I could and test / inspect them.

Kill switch?
Failing that all the wiring is in the headlight, a poor connection will stop it starting.
2002 model, should be CDI so no points to play with.

lol, made me giggle reading that then
the lights used to come on when i switched them on with the ignistion on and bike not running, but they wont come on at all, and the bike just wont start

yeah i had a look at all those wires behind the headlamp...everything looked connected but i didnt do a thorough check tbh
would that effect the rear tail light (even tho it works when i press brake light?)

its getin picked up in the morning now to be taken to the garage was hoping to sort it out myself...il post up what was wrong with it
cheers everyone

[TUG]

Its tough when it comes to electrics, lots of wires, undetectable breaks and stuff. If its been left out side then if its got a break it wouldnt surprise me.
Let us know.

Just an idea, could you use a volty currenty meter thing to see if theres anything going round the bike?

The headlights on my cg ('77) work off the engine, not the battery, if the bike stops, the lights go o

Wish i had that maybe even a half decent 12v battery for a pair of heated grips

bike is back from garage........a bulb had blown out which effected the circuit (i did check the bulbs and they didnt seemed broken in any way etc) and the starter motor had stiffened up or something along those lines

the bike kick starts fine....just takes ages to heat up because of the weather, but the electric start still doesnt work, the mechanic says its due down to the cold..... because its soo cold its effecting the battery and there for not allowing it to tick over the bike

is this true??

cheers

[27cows]

Sounds like cobblers to me. Surely the CG will run without a battery? I know the old ones did because some arse nicked mine from my first CG (it was flat and needed replacing LOL) and I was able to ride home with no bother.

[andwat16]

it runs fine and kickstarts, just the electric start isnt working

[27cows]

Ah, I should have read your previous post more carefully

The cold will certainly affect the battery, if you're a good few degrees below freezing.

[TUG]

Bulbs blow on CG's all the time, on my pre-electric start CG's it wouldnt affect starting tbh. Glad its fixed and you can enjoy it, whatever you do don't sell it, i miss the one i sold and i miss the one that got robbed more than ever.

I know this is fixed now, but one thing for the rest of you to note. The brake light usually works when everything else is turned off, this is a safety feature so that if you have a total electrical failure on the road then other vehicles can still see your brake light.

I assume to do this it runs as a totaly independant circuit (on old bikes, newer ones probably do something clever).

I'm surprised that one bulb being blown knocked everything else out, my money would have been on the main fuse.

[Midriff]

I had a 2002 M1 and my lights never came on without the engine running. Had to have the engine running for them to even come on.

It is spose to be like that right....
