Re: [St] [ST]alternator troubles: follow up

[Frederic NIZERY <frederic.nizery@xxxxxxxxxxxxxxxxx>]

All,

Here is the follow up for now:

One of the three  stator coil is fried.  That explain why the coils are 
now connected
to the ground. It is a triangle arrangement by the way. The insulation 
has  melted on
one core of this coil. I have two options: rewire or buy a new one.

I now have to double check the regulator/rectifier. I will simulate the 
stator w/ a transformer
w/ a big condenser + power resistor as the load. A bulb could also be ok.
Now I have to figure out how a bad rectifier could have fried one coil. 
In fact as
only one coil is out, I can only suspect one or two diodes of the 
rectifier. I can't imagine the price
of stator+regulator/rectifier. My bike was bought new in August 2002 
that is 5 years and half.
Re-wirering is probably  the best option but painful. Plus the core 
insulator is  melted.  Epoxy
+ thin glass fiber (50 gr/m2) can probably fix that.

The bike will stay a long time in the garage I think.

Fred
