according to the manual..

section 14- 7

it states that the resistance of the coils ( ie between the yellow wires ) should be 0.1- 1.0 (20 )

what does the (20) mean? ( my guess is the setting of the specific meter they recommend )

I have a resistance of 1.6 ohms that does seem to be out of spec a wee bit?

here's a snap of the relevant page of the manual.

there is no continuity to the frame...

I measure the voltage when the engine was running... only giving me ( i think) 3 volts.... I read Krusty's post said it might give quite a bit more?

stator fubar's anyone?

there's a hole in my bucket!!

ok so I bought a fly wheel puller a while back... looks like I cant get it in unless I unscrew the RHS pulse generator...

this is what it did to my allen key! took the end off!




anyone got a picture of the tool I need to pull it off with out removing pulse generators?

and the universal holder is recommended? or the bar thru the spokes will be fine to stop the engine rotating?..

is the fly wheel on clockwise to loosen as opposed anticlockwise to loosen?

thanks !

i have sprayed screws with WD 40 hopefully that will loosen them up a bit,, but wondering if a different puller will help? mines a 3 pronger and looking had to get in there=!

The flywheel puller I use just screws into the flywheel, its a left hand thread, the puller is common to most 2 stroke cranks. 27mm x 1mm LH thread, your mechanic will have one for sure.

No need to remove pickups to use.

A three pronged puller is going to damage something.

The resistance between the three yellow wires on the Mk3 stator that I have is 0.6, 0.8 & 0.8 ohm.

The flywheel is easy to get off with a puller that screws 'the wrong way' into the flywheel (as has been mentioned) and then has a bolt that screws the right way (clockwise) onto the end of the crank to pull the flywheel off. Very easy with a ratchet gun but you could put the bike into 6th gear and stop the rear wheel turning some way and use an ordinary socket set.

You don't need to take the flywheel sensors off to get the stator out but you do need to remove the gear selector sensor from the gearbox as this is part of the mini loom.

thanks gents!

any chance of a piccy of the puller I need? its a lot easier to find something here if I can wave a piccy at them...

would like to get one asap!

missed 2 sets of rides this w/e

like this?

or is this one better?

One like the photo (they're all the same).

thanks Kmk1! managed to get one...

but still flumoxed at the first hurdle!!! - ok I spent all of 5 mins trying cos my wife's bike throttle return cable had disappeared! emergency override initiated

I tried to loosen the nut holding the flywheel,,, ( 17mm spnner ) put the bike in 6th and wedged a bar in the back wheel

I guess it hasnt been off since it was made - cos it aint budging! back wheel strains - then something inside the engine slips ( clutch???!)

it is a reverse type thread on that center nut? so what would normally be tighten is loosen.,,

tomorrow I must win this battle!

You need to find someone with an impact/ratchet gun. 5 seconds with one to get the nut and the flywheel off. Will do it even with the engine out.

I'm in! sort of! ( got a flywheel holder )

cant remove the loom because the pulse gennys will not budge.. with fly wheel off I managed to get impact driver in there... but its shredded the bolt! ( maybe not a big deal - I can just drill the head off cos I will scrap this side of the crankcase for sure ! )

BIG question,, I realise my meter isnt errr optimal when I short the probes out.. get a reading of 0.9 Ohmmmms

so if I do maths... then my stator is in spec!! ( spec said up to 1 ohm is ok - I'm registering 1.6 - pretty sure you can just add reistors togther to get the total resistance )

but for sure the voltage I am getting out the stator is very low! only 4 volts ( if I rememember ) might have been 3 Volts!

any guesses anyone?

I can see some cables got a bit scorched from the new exhaust.. my bad - but those go to the gear detector- and its just one wire thats a bit brown - but it didnt get thru to show the bare wire fortunately...

Something's wrong somewhere . Either with your measuring equipment, the stator or .............

I'm not sure about your calculation re the resistance. Have you got some resistors of known resistance you can test your equipment with (You can work out the resistance from the colour bands around electrical resistor components).

yep - feel confident its measurin volts ok ( ie a 9v battery is about 9 V )

which means the stator is only giving out 4 volts on each of those yellow wires ( measured between the yellow wire and the frame or engine block )

so if the stator generator isnt pump out enough then the regualator aint no miracle worker......

anyone like to venture it s the stator?

could a short wire *somewhere* produce this low voltage at the generator output?

It's got to be the stator otherwise there would be some serious heat build up on the shorting part of the loom to make the potential difference that low .

thanks for the hint Knk1! I think I have an answer!

it seems like the regulator... so looks like you were right - it was heating up the regulator until it started working... and I was testing it whilst HOT!! I thought it was hot - but thought thats why they have a heat sink! DOH!!!

I just went and measured it now - and bingo! no continuity at all thru it! ( should be 0.5 ohmm to 15 Ohmmm )

also just researched - you can simply add and subtract resistance - so taking 0.9 from my figures... so that means my stator is OK!!! ( i hope! )

anyways! I am looking for a regulator now...

any other regulators I can make fit? ( I checked my local parts places for stock las week and none in )

- I had a quick look on flea bay and the fireblade looks close - has the right number of wires,, of course I have no idea!

about to search the alt parts thread!

thanks
