Bridge the two large terminals on the solenoid with a screwdriver (make sure its out of gear) its the best way to eliminate the solenoid 

if the battery and starter are ok it should crank 

and check the connections

Be brave Steve and, as suggested, use something chunky to short out the solenoid terminals. Used to start my Fordson Dexta by doing that every time but it left some interesting marks on the spanner I used to use biggrin

If it spins the starter motor then you need to pay the shop a visit here.

The genuine Yamaha solenoid is expensive but the cheaper after-market ones just aren't up to it and used to overheat and stick on meaning the only way to stop them was to disconnect the battery no 

If no spin then you need to check the brushes - a new brush set is available here if needed.

My TTR has developed a new problem, when i push the start button i get a click from the solenoid and that's it, is it just the solenoid that is faulty or could the problem be elsewhere?

Stuck brushes in the starter motor? Give it a few sharp taps to see if it frees them up.

Loads of starter information here http://www.ttr250.com/Starter_information/TTR250_starter_motor_information.htm

I tried tapping it, but no luck, if i put the bike in gear and rock it i can sometimes get the starter to go, not sure what that means though.

Take out the starter and try it off the bike to see if it will run, could be the solenoid switch as well

Yes - the contacts inside the solenoid can burn out so the solenoid clicks but doesn't send juice to the starter. Simple to check by shorting out the solenoid terminals (from battery to starter) with something metal and substantial - but be careful!

See http://www.ttr250.com/Starter_information/TTR250_starter_motor_information.htm

I have taken advantage of a long cold dark evening to go through the starter motor mega thread.

I think that I have pretty well extracted all the relevant information and put it on a single web page to make it easier to access - hopefully!

Please have a look through and let me know if you spot any errors or omissions. If you can suggest improvements that would be great!

Brian

Hi guys,

I have a TTR Raid '96. When I switch the start button the relay clicks but the starter motor does not turn. I have recently cleaned the starter motor and the battery has a good voltage. I checked the voltage arriving at the positive terminal when the start button is depressed and a voltage of under 1 volt is arriving.

What do you guys think?

Relay repalcement even though it's clicking?

Hi Cassar and welcome to the forum!

First check if it's the relay/solenoid causing a problem. 

Make sure the TTR is out of gear and then bridge the two large terminals on the solenoid with a screwdriver.

If the battery and starter are good then the engine should turn over. 

If they do then replace the solenoid.

If they don't then you have a connection problem or need to check/replace the starter brushes.

Brian

Hey guyz cheers for the swift troubleshooting tip. Unfortunately it is not the solenoid.. I'll leave it up to the mechanic as I don't have much time on my hands..

I find this site very useful for multiple inquiries and curiosities. Keep it up!

Sounds like brushes, easy check, take the back off the starter and see if they have jammed up and not making contact.

Good day. My (old) starter began to peel only a piece of shaft rotation. There is no power to turn the shaft and it devours electricity very much. Aku is new. What should I look for?
Thank you

It sounds like the brushes are sticking or worn Tom.

This thread might help you.

Thank you, Brian. I thought that if the brushes are bad, the akku is not running out. I'll check it.

Will add that if I help with kick starter it starts right away. As you kick the start only, it starts very hard.

(why is my posts so big and empty at the bottom?)

 You haven't filled out your "Signature" Tom, mine tells me that "You're never to old to learn something stupid"

To give yourself a signature go to your profile page and there is a box in the top left corner where you click on Signature.

Make something up and stick it there.

It will fill the vacant space on each post you make.

I think I'm very dark. I have read the three pages and I do not know. When I start the start, the solenoid knocks a lot. The starter only moves a little. I connected the starter directly from the battery, the starter just moves a little. Do I have to bow to Steve for brushes?
I apologize for my insistence and technical weakness.

It sounds like the brushes are sticking or worn and need to be replaced Tom.

Thank you, Brian. I have looked at your instructions and will try to fix it with my old hands.

And whether after disconnection 1 gear idler, the starter rotates well or is the brush not good?

I also took out the spark plug and the starter spins well. Used brushes?

If the starter is working properly without a load then it does seem to indicate the battery may be the problem.

Are you sure the battery is OK Tom?

If you replace the spark plug and then attach a good 12V battery (such as on your car) using jump leads, does the starter work properly then?

Brian

I removed the starter (thanks to Brian for the instructions). Brushes look like this:

They look very clean, do the magnets move freely and the springs return them, when pushed in?

I doubt it too. I ordered a solenoid, unfortunately, I think Chinese and sent a battery to check the inrush current and possibly warranty exchange.

This thread shows how the TTR solenoid works. It is usually the contacts that fail.

This thread shows how to replace the solenoid.

Beware the after-market solenoids. When I ran Totally TTRs I started to sell cheaper after-market solenoids but, after several failures, I stopped stocking them. They aren't up to the job and the contacts melt and fuse together such that the starter is left permanently spinning. The only way to stop it is to disconnect the battery. Not ideal if you are just about to pull away from the filling station having just topped up as happened to a customer no

Use a new or s/h genuine part e.g. as here

Thank you Brian, I know this thread. I also read about cheap selenoids. I'm gonna make a present and if I make money, I'll buy Steve. I have already spent too much money now. Starter, all gears, battery, etc. 10-15 starts were good and finished. That's why I am looking for what reason.

Have you replaced the sprag Tom? I am trying to think whether something else is causing the problem.

I think the sprag is good because he made a car battery out of it. My battery was new and twisted. Now he has 13V and he has strength. Only trrrrrr solenoid.

The cause of the trouble is simple. The new battery was broken. With the new second everything works. Thank you for your help, I also met a lot.
