Stator generator problem

[Mazalak]

So bought my v strom on a whim pre covid then boom lock down put the bike to my local garage good friend to change the chain for me phones me to tell me the bike not charging …… so he replaced some parts etc turns out the wiring loom had been on fire at some point .

So with in this time the bike has had a new stator new rectifier new battery and last week new flywheel/generator and to my horror still not charging done the usual tests with the stator checked resistance 0.4 each coil …… 215 at the pick up coil but no voltage ….. there is a f1 on the dash but it’s c44 oxy sensor help I’m going crazy flew through it’s mot and can’t use it sorry if there is another post like this couldn’t find it in the search

Further loom damage that hasn't been found.
Has the garage got another battery you can try, you never know.
Was the bike running/charging when you bought it?
You say it isn't charging but what are the readings?
Upt.

New battery in mate and rectifier and stator and generator…… the ful loom replaced ….. the stator is measuring resistance all three readings 0.4 and the stator pick up is resistance is 215 but no voltage coming from the stator when running wondered if we take not Earthed right somewhere

   Have a look at the two negative cables coming from the battery,the heavy one goes to the main earth on the engine,the smaller one is the rectifier negative back to the battery,there is a coupling about halfway between the rectifier and the battery,make sure by splitting the connector that everything is OK inside.Good luck,it’s a pig to get to.

Are you sure the flywheel had been been changed, your model has an issue with the magnets coming loose.

[Mazalak]

Yeah I replaced it with a new one from rm stator in Canada got it shipped across

[kwackboy]

Test the stator while its running.
Charge your battery, unplug the stator connection to the regulator then start the bike.

Use your meter on the high voltage setting and then test the three same coloured wires, they'll be either 3 yellow, 3 white or 3 black wires depending if your stator is genuine.

Use your meter probes to test every combination of two, they all should achieve 45v +

Did your mechanic replace the stator magnets when he replaced the stator, etc?  There have been a few complaints of stator magnets migration and a fix to the stator magnet problem,  https://www.stromtrooper.com/threads/stator-magnets-jb-weld-pictures.400946/

[Mazalak]

He tried Jb welding it back on but still wasn’t working so just bought a new one mate also there is no power coming from the stator running

[kwackboy]

Then you have a bad stator

[Mazalak]

It’s a brand new stator 🤦🏼‍♂️ also rm stator has stated in installing to make sure the pick up coil is as close as possible or adjust to no less than 0.010 looked inside it can’t be adjusted two bolts holding it on like they are stating if it’s not close enough it won’t pick up ?

[kwackboy]

The pickup is nothing to do with the stator with regard to charging.

[Mazalak]

New stator must be goosed then I’ll
Order another 🤦🏼‍♂️

You need a garage that's not your good friend, but knows their stuff maybe

[Rusty Nuts]

Geography will be counting against much choice, I'm guessing.

[Gert]

There is a stator resistance and voltage test in the service manual, that you can follow to test your current stator. The resistance test includes a resistance to ground / earth. You don't want to dispose of a working stator without first correctly testing it.
It is possible that a stator magnet or two may have been turned around / incorrect polarity pattern, if any loose magnets where re-attached.
It may also be that the method used to test the stator voltage was not followed as recommended in the service manual...

So checked everything…..
I have replaced this week the generator a second new stator new battery and rectifier and still it’s not producing volts from the stator I literally can’t do anymore and don’t know what else to do just a huge money pit and still not on the road …… anymore ideas etc would be welcome

[endintears]

My idea/advice is find somebody (paid if need be) with basic auto electrical  knowledge and show them the information I have attached.

[Barbel Mick]

Have you checked the earths & the connector as Ianmc suggested in reply #3?

[kwackboy]

Stator and generator are the same thing ..

A charging system consists of a stator that sends AC current to the regulator turning it into DC into the battery.

Remove the loom from the equation and connect the positive and negative coming out of the regulator direct to the battery with some spare 30amp wire .

If its charging then there's a loom problem , maybe a connection that's not connected ..
