Posted: 18:14 - 14 Aug 2023 Post subject: ST1100 Charging issues. |
|
|
Is there anyone near to Southampton that can come and give me a hand before I scrap the bike?
I cannot tell for the life fatham why my battery is not charging. I have done the checks from the Haynes manual testing all the yellows from the alternator, testing the black and white wire, and I think they are correct.
The RR test in the haynes makes no sense to me. I have tried 3 regulators 2 standard ones and a brand new electrix one that I paid £100 for and nothing.
People are saying the starter solenoid has nothing to do with the charging circuit, yet the wiring diagrams show power coming from the RR through this. Prev also when the fuse was missing from the starter the bike did not charge.

I thin it was 96 ish onwards they started to use 'proper' alternators.

Gulp, gonna risk looking stoopid here but what are the differences?
I figured all, apart form the most basic mopeds, systems used coil(s) that fed multiple AC lines into rectifier/regulator that provided a DC charge voltage of about 14.5V, although I also recall being told alternators had the R-R bit built in.
How far off am I? ____________________ Now: A100, GT250A, XJ598, FZ750

Bikes usually have a 3 phase AC generator on the crank
this is basically 3 sets of coils and permanent magnets whizzing around
it which produces AC power.
This AC power goes out to the Rectifier/Regulator (RR for short)
where diodes in the rectumfrier turn it to DC as yet unregulated.
This unregulated voltage may well be a far higher voltage than the bike/battery needs so needs to be regulated to usually close to 14V
This is usually done internally to the RR by shunting excess power to ground hence the need for fins to dissipate the heat produced.
so basically, wasting some of the power produced by the stator
'Proper' alternators like you'll find on most cars do it all internally
they generate, rectify and regulate and give out a steady DC voltage
of around 14V to power the electrics while keeping the battery charged.
They don't use permanent magnets which produce a fixed output like a bike stator which produces power whether it's needed or not
but have field coils which can be altered in response to demand ( load)
by altering the magnetic field strength.
This makes them more efficient as they can put less load on an engine
when demand is low (battery full charged, sunny day, no lights or heated grips on etc)
that earlier ST has what initially looks like an alternator but
closer inspection shows it has no slip rings brushes or diode pack
and regulator like a pukka alternator.
It's just a fancy pants faggoty assed external stator setup ____________________ bikers smell of wee |
