starter button broke

hello just a quick 1 my starter button wont crank my engine and i have no brake lights when i pull the brakes. the bike will start if i jump the solenoid and apart from that everything else works fine like lights and indicators horn ect. any ideas what it could be before i spend the whole day stripping plastics and checking wires? many thanks kev.

 

Hi
Try to bypass your brake switch if you have no brake light that could be due to that
Or the solenoid

Romain

 

Hello I will try and bypass both switches tomorrow and report back thanks. I've ordered a new solenoid which will be here Friday so fingers crossed

 

+1 on the brake light switches, if they dont work they need changing anyway, its dangerous to have no brake lights

 

yeah im gonna try and sort that. bypassed the switches but no joy. how do i figure out why theres no power to brakes/starter button?

 

Check if it s not your brake light bulb which is out
Then check on the exciting side of your relay if you have 12v when you press your brake and start button
Maybe a fuse on the brake light circuit but I doubt you have a fuse There
maybe the main fuse which bike is it ?

 

tried changing the tail light bulb? sounds dumb, but i seem to recall having this problem at work before

 

havent got a spare but looked at it and i can see there no break between the 2 wires so it all looks good

 

Which bike is it Kev ?
Sometime the bulb look fine but in fact they have a brake on the inside
What tool do you have to test your circuit and do you know how to use it ?

 

romain can take over here, he is in charge while im out....

 

hello lads sorry been working on it all day. got a multimeter and not to sure on what to do. had a break through i think it was a earth on the frame had a bad connection ive filed everything down and my start switch is working and my front lights. im having issues with the brake lights still. the back light and brake light is coming on when the lights are switched off. messed about a bit but cant get it right. what would throw these off like that? every wire + connector has been filed down nice and shiny apart from the brake light switches inside. any help would be great cheers

 

If the brake and rear light are on all the time
It sounds like one of your switch is faulty or came off his place
And I only say that because both light are on I am wondering if you did fit the bulb correctly
Since they are twin filament if not logged correctly the two contact at the back could be touching the same contact
First disconnect both brake switch one at the time and check if that change anything
If that doesn't make sure the bulb is fitted correctly you will see there are two spigot on the bulb one being deeper than the other one so try to fit it the other way around
Let us know how you get on

 

sorry for the late reply ive been stipping down and sanding the switches, fidlly little things and very hard to put back together. il try them now and report back

 

right everything works including the rear light but still got no brake lights switches are in good condition now but still not working. the bulb wasnt screwed in properly haha thanks. the problem isnt the bulb on the brakes though because both parts worked when the bulb wasnt in properly if you get me? what else could i be missing? im soooo close

 

now you want to figure out which one is the live and Earth at the back of your light you either have
one live and two earth or
Two earth and one live
if your light circuit is working check it
and the one which feed the common feed (the side of the bulb) I suspect it should be earth
When you press the brake and your light are on you should not have any live to one of the contact
If that's the case your sure it s not your bulb and you have to check the continuity between this connection and either of your brake switch if that's ok
By the way I take it you checked the connection which is roughly 20 cm away from the rear light assembly?
So if the continuity is fine and if it s as I suspect a live which you are missing you have to check either of your brake light switch for live

I hope I made sense and you understand
Let us know how you get on

 

I sort of get what you mean mate yea I will get the meter out on the back connections tomorrow and failing that il try and get me hands in a new bulb. I checked the block connectors that are about 20cm away. Pulled them all out and filed so everything was shiny and getting a good contact. Will have to try a couple of things as soon as I get the time tomorrow and report back. Thanks again for your help. Also my bike is a lexmoto zoom 2 125cc gy6 Chinese clone. Ano Ano I can't afford a real bike yet haha

 

Cool no problem ,
The good thing with a Chinese bike you learn quicker about it lol
My ex used to have a baotian
So I know a bit about those Chinese bikes

 

haha yeah ive learnt a lot from having i chinese bike mate.right ive checked every wire from the rear light to the switches and there is continuity in every single wire as i got a beep on the meter, the rear bulb has 2 green and 1 brown so im assuming theres 2 earths. still not brake lights tho mate im stuck now tho

 

No don't stress
Fault finding is just about staying calm and methodical
Or as I suspected the brown is earth and the green are live check that?
Next thing is when you go to your switch do you have live and if so what is your voltage ?

Keep calm you will get it working

 

ive only checked everything for continuity tbh mate how do i check the voltage on the switch? just on my way out to try and get a new bulb
