Fireblade stator problem ?
Just had a friend round with volt meter to check wiring etc and this is what we have come up with.
Resistance across all pairs of yellow stator wires approx 0.4ohms all equal
Voltage across all pairs of yellow stator wires approx 25-30v ac when revved all equal
0 ohms resistance from red @ black rectifier wires to battery terminals live @ earth
Battery terminal voltage
Engine off 12v
Engine on 13v
Side lights on 12.5v
Main beam on 11.9v
High beam on 11.3v All at 4000 rpm
Yellow stator wires get very hot within minutes and connector had burned black
Hope this makes sense
Any suggestions
Cheers Kev

Thats a very common problem on early fireblade looms 3 yellow wire connector block has very high resistance and burns
CURE- Cut it out and replace with new connectors

i had same probs using original bike reg/ rect as it cant handle the extra power drain & either the wires burn up or the unit itself fails,
upgrade to 1000rr with a small PC fan blowing across it

The newer ones use mosfets, whatever they are, and are much cooler running and stabilise voltage much more efficiently apparently.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
