ignition issues

[leeharrisom]

hello to you all newbie here please be gentle

I have just bought a Chinese cbr 125 copy and yes I do no they are shit and the bain of motorcycle existence but am on a budget and I do intend to change pretty much all of the bike just needed a base and got it on a 2012 plate for £250 of a auction.

now for the help part: the bike has no key so trying to bypass this just to see if the bike will start, as dont want to spend money on it if I have bought a dud

now before you tare me a new one I have bought this and I am not a dirty scum bag who pinches bikes and I can send a screen shot from the auction site to show I have paid for the bike to anyone who thinks otherwise.

so if anyone can help it would be much appreciated.

many thanks and hello

lee

Haynes Book Of chinese Fake-Aways.
Read the wiring diagram.
£15, probably as much as buying a new lock, but come in handy when you want to tackle the rest of it.
Of course if you're a low life skum-bag, you'll have to shop-lift one from Halfords
Figure out the ignition circuit and bridge the appropriate wires.
Its not too difficult... ten year old twockers can do it

HAHAHA thanks mate,

ave bought a new ignition of ebay but now think i may have broke something else messing on with the wires as the fuse blew of touching the ignition wires together so when i press the starter button the live wire gets hot and the stater motor did go at first but now no life

help please

cheers lee

yer just read that sorry for the broken English you wouldnt think I was born here lmao

I will try again

before I got the new ignition barrel and key I tried a number of different combinations of wires to try and get life to the electrics and blew the fuse.

after this I removed the fuse from the circuit to get past this but by doing this think I have broke something more serious.

then after finding the right combination to get the neutral light on I tried the starter motor which did turn a couple of times then I seen smoke coming from the wire so removed until the ignition came.

wired the ignition up after this got the same neutral light but the same thing happened with the starter motor :S

not sure what i have broke as all light work ect but as soon as I press the starter button things all go wrong as it starts to some turns once then dies and get a smoke and a clicking noise

can you help.

cheers

Is there a chance you inherited a starter motor fault and the solenoid or its wiring are a weak point?

that may be right but its a 2012 model would it go that quickly ?

even though it is a copy ?

You by-passed the fuse?

You do know that's probably the most reliable part of the bike right?

It's never a good idea to bypass the fuse as it could allow too much current through the lower rated wiring causing them to heat up and start a fire resulting in a nice little explosion. Usually when you least expect it causing you the most harm.

You will be needing a multimeter so you can go through the whole system with it and locate the fault.

You're in for a world of headaches with this one I think.

Electrical parts for clones are usually of very poor quality. Connect a car battery with booster cables and try the starter. See what smokes. Its unlikely any small wires will get hot as they are fused. The starter wiring is not but it is thicker. Corroded or loose connections to or from battery, earth and starter/solenoid will certainly get hot instead of passing current.

Then theres little hope. I earn money from people that bypass fuses. My interpretation of his message was different. I like your new name Uw

lmao thanks uberkon glad impatient people like me have there uses haha

next time I bypass a fuse am gunna think of you counting your cash lol

am gunna strip the bike down a bit this weekend anyway changing all the lights and cutting the tail down a bit to suit me new cafe racer rear ect so will have a play around then

cheers for the reply's but if anyone has an idea what I have melted this would still help

cheers lee

Thanks, new attitude, new name.

I think that the OP should post up a video that shows clearly whats happening. Not some crappy iphone video.

If the wires from the ignition are smoking then there is either a short somewhere, which I would have thought would stop the electrics from working, or the wires are trying to pull to much current and overheating.

Questions to the OP:

1 Did you replace the fuse?
a) Yes, good.
b) No, STOP messing around with it, go buy 2 packs of 5 fuses and get it replaced.

2 Is there any signs of melted cable coating where the smoke come from?
a) Yes - current is overheating the wires most likely and melting it.
b) No - no frigging clue.

2a - if you HAVE replaced the fuse, then there is something major wrong. Get a multimeter, put the live probe on the wire, and the negative probe on the frame, try starting the bike and make a note of the current and voltage. Post it up on here.

If you havent replaced it, then refer to 1b.

Because it is an electrical issue, make sure you buy spare fuses.

Oh, and buy a can or two of ACF-50. This will increase the life of your bike. It will need a good coating on metal surfaces every 6 months-ish. It will help prevent rust forming.

If it is like most i have seen, in this order, burnt solenoid, burnt large spade style connectors, or where lugs are crimped to cable but probably best to have a look first. Im sure all will make sense eventually for you.
