Yamaha SR125 Electrical Problem (continued!)

[Toby_Smith]

Hi there

I posted this thread a bit ago: http://www.themotorbikeforum.com/viewto ... =5&t=28627

Since this I have charged the battery (which shows up as been fine on the optimate) and tried two other batteries but still have no power unless the bike is bump started.

I have cleaned up any earth connections I can find and also given the battery terminal connections a good clean. Still no joy.

Any ideas?

Absolutely clueless here!

Cheers!

So you are saying the battery isn't getting charged when you ride?

Have you tryed changing the rectifier or looking at the generator?

Cheers, i just had this problem if it's the same problem.

Does it start up the first time from when you have charged the battery?

Or does the electric start not work at all? If so, sounds like the starter motor.

Even a fully charged battery won't even switch the ignition on.

I have a fully charged battery in it. I turn the key and don't get any electrics at all.

Once I bump start it I do, but then if/when I stop the bike and the engine is off I won't get any electrics at all.

Is there any chance it could be the ignition switch? The ignition needs changing anyway so I will be doing that, but it'd be handy to know if there is anything else I should check first.

So to clarify, it isn't a case of the starter not working, none of the electrics work without the engine running. No lights, starter, horn etc etc

I would have a look under the seat for the fuses, could be a main fuse thats gone, therefore disabling the main circuit.

the fuse should be 20amps, and on the battery red/positive cable.

Funny you should reply...I was considering PMing you instead of starting a new thread heh.

A fuse did cross my mind, I will have a look tonight. Any idea what this fuse will look like? I'm guessing nothing like the ones from cars which I'm familiar with?

Blade fuse like below (gotta love ebay) and it will be mounted on a rubber bracket to the frame

Thanks mate, will have a look later!

I think i may have a spare one kicking round off my old SR which I had to break after it was stolen and recovered in a not so nice state.

Will let you know how i get on!
