Hi All,
will resurrect this old thread,hoping someone can either confirm or correct me.
f800gs got more difficult to start up so pulled the battery and give it a proper charge. bike was running fine whole week until today- again difficult to start.
so started up, and with multimeter checked across terminals, reved to about 5k and voltage stayed at about 11.5 - so not charging.
1.
took our regulator, that have three yellow wires, two green and two red/white. checked diodes with negative on yellow and positive on green terminals, nice consistent readings at about 470. then swapped leads and had positive on yellow wires and negative on red/white and again nice consistent readings across all three yellow at about 460. is this the correct way to check the regulator and if yes I believe the test proved regulator to be fine?
2.
stator, checked resistance across three yellow wires and was getting about 005 ohms which again I believe is ok? started bike, reved to about 5k and was getting about 80-90V AC, again I believe thats correct?
however, when I checked for the continuity in between yellow and engine bolts (earth) I get continuity signal, would that mean my coils are burned and shorting ?
is it pretty safe to say i need a new stator? I dont want to pull the cover off and check for burned stator (apparently pretty common on bmw 800) as I like to charge the battery and need to use bike until new one arrive and I can swap it hopefully without leaving me stranded
cheers
