My bikes broken [img alt=:cry2:]http://static.tsrfiles.co.uk/images/smilies/cry2.gif[/img]
its something to do with charging the battery.
if i start the bike and then disconnect the battery it cuts out.
tested the resistance of the alternator coils and all three are reading at 0.6 ohms (the spec is 3.36 - 4.4 ohms). this is out of spec, though all three are evenly so. There is no continuity to earth.
Mr Haynes says i cant test the rectifier, i can either swap it for a known good one or take it to a yam dealer to do it.
any ideas what to do next?
Why on earth would you disconnect the battery with the engine running in the first place? :rolleyes
i had taken the battery out to charge, and hooked it up to a 12v power supply
ime no electrical wizard but ive always been under the impression that you should never disconnect a battery whilst engine running can do all sorts of damage?...all you got to do is leave in situ and connect a meter across the batt terminals and see what it reads both on idle then when its reved to 3 t 4thou it should be approx 14.2 + at about 4thou...little less with lights etc loaded up!!...unfazed or fazerider will give you the correct figures

[/quote]....the only reading you can get from your fazer is through your battery?..that will show what your charging system is doing??...so the battery as ...got...to be connected :rolleyes ......
when the bike is giving out the voltege, it will give the PD across the battery connectors, weather there is a battery there or not

If it was me I'd put the battery back in and push or jump start the bike. Then hook up the meter and check if the bike is charging the battery or not.

Off the top of my head only a dynamo will generate without haveing a voltage applied to it and most if not all charging systems these days are alternators which require a battery connected to work or have I totally missed the point?

Andy ...thats what i think too andy!!...and ime sure you should not disconnect whilst engine running :rolleyes ....ime also thinking if the rectifier wasnt fkd before?...it may be now!!!!!!...ime sure the unfazed wizard will be along shortly to put us right?

stuck the battery back in
bike off - 12.2v
when the bike was started it started about the same and dropped as the rpm increased.
this implies the charging is not working, stator tested correctly - going to try fitting a friend's rectifier tomorrow.
not going to try taking more readings tonight neighbours are getting home and my exhaust is a bit holey.
cheers peeps

Andy the alternator is just a coil (or three) of wire with a magnet spinning alongside it. a magnetic field moving across a conductor will induce a current in that coil.

would turning the ignition off not essentially do the same - causing a brake in the circuit.

Nah not my style. Have you ever been to Ireland? You seem to have a keen interest in the place

cheers peeps ....if it does turn out your rectifier is goosed i have a spare i will let you have cheap?...pm me if you need it ..clive.

Sorry to hear that. You should come back. There's some great biking roads here
