A forum for owners of Yamaha TTR250 trail and enduro bikes!

Have been playing with the wiring ?
you can NOT run power from the battrey
though the starter button....

Don't push the start button again....you will end up turning it into a crispy critter

you now have DC current going though it
the button is to small to handle those amps...

you should have AC current that is picked up from the recifier
with a diode in the system to stop the DC & AC current coming in
contact with each other...

Still got the diode for you Dwight.

I'm stuck here....i can get the bike running by sending power directly to the post on the starter relay.....im just not sure how to set up my ignition wire or why mine isn't working

my original killswitch blew out the diode (s3h-02) ....since I bought a new harness and switch ...(2 switches one a on and off 3 prong switch for the killswitch and a 2 prong push button switch for the star button) 

everything worked for a day correctly the killswitch worked and the ignition button worked  .....then the dioide in the new loom burnt out ....(not sure why ....I believe it had something to do with the 3 prong (ground,earth,lead) switch. I'm not 100% sure but the diode blew when I flipped the killswitch from on to off .....

i replaced the just the diode this time and my  killswitch started working but my ignition button doesn't work ....I can get the bike to crank by bridging power directly to the post on the starter relay but nothin happens when I press the button ....I tried touching a wire from the battery to the blue wire on the ignition button ....this worked in the past in cranking the bike .....now I get nothing ....i wonder if I've shorted something out in the cdi

There is an explanation of the starter circuit in this thread which may help - http://ttr250.activeboard.com/t48824180/starter-motor-problems-and-solutions-megathread/?sort=oldestFirst&page=2

I can't fathom out what has happened to your circuits as I can't follow the wiring. It is always best to try and match the original wiring colours to help diagnose problems.

On the original starter switch I have in front of me there are 4 wires. A pair of red/white, a blue/white and a black. The pair of red/white wires go to the red cutout button and the others to the grey starter switch.

Starter switches rarely go bad. The only problem I have had is with the contacts on the grey switch getting dirty and a quick clean has always got it working again.

In circumstances like yours I would just go back to the standard fittings - switches and connections - and hope that solved the issue.

In the first picture the blue and yellow connectors are the 2 red wires (one turns brown after the connector) and the other blue wire runs to a ground (in order to turn the light on in the button)

 

in the second picture the button is attached the blue and black wires (black wire becomes blue wire after the connector)

On the original switch it did not ...when I pressed the button it did not make a circuit .... Now on my bike the 2 wires blue/white & black do not make a circuit ...one has 12 volts and the other Is ground ....the new switch I have is good and when I press the button it makes a circuit ....but the 2 wires it plugs into don't

dosn't look to flash.... fix it & yer soon find out...
