F800gs Stator checking and replacement.

Replacing the stator on a 2009 BWM F800gs Motorcycle. This is a known weak point on these motorcycles. I used an electric-sport stator replacement and have not had any issues, but it’s only been a month since installation so that does not really mean much. My current understanding of the root issue is that the voltage regulator/rectifier is the “shunt” type. Shunt type regulators always draw full power, 400 Watts in this case. This means that stator is always drawing/creating 400W and creating that power generations associated heat. This heat breaks down the insulation and the coils start to short to themselves (hence 0.2 Ohms) and to the case (hence measurable resistance between stator legs and case) With all this internal shorting, the problem builds until one day it does not produce enough AC voltage to feed the voltage regulator/rectifier enough energy to charge the battery. This issue presents itself by at first weak starts, then the ABS light comes on, then the headlight turns off, then the fuel pump gets weak until the battery is just drained and there is not enough to keep up with fuel delivery to the engine and it shuts off leaving you stranded. This can happen in a single ride. I recommend installing a method of monitoring the battery voltage live on your bike so you can see this issue coming quicker. If you do not see the voltage above 13.5v when running, you may have this issue.
