Hi, I have a 99 XXX model which is lovely except... it burns out the tail light filament on one of the tail light bulbs. The other bulb is fine and both bulb's brake light filaments are fine. Any ideas? Thanks.
Has the loom fix been done ? - that can cause all sorts of electrical gremlins.Ok, thank you gents. I'll go over it with the multimeter today. Bulb holder looks as clean as a whistle. I'm in denial about the reg/rec to be honest. I had that issue with my ex 'bird', nearly made me sick.
Yeah just be methodical go through the system, like CBRDEANO put, check your loom factory plug for corrosion as well, it's got to be the 1 thing that can cause weird electrical problems when they go bad, keep at it you will find it in the end.Ok, thank you gents.

Take the charging system out of the bike loom and use a much more efficient R/R.Can I ask what's the charging system upgrade?
Thanks for the explanation, I was thinking the only way I could think of was to go direct to battery with the reg/rec.Take the charging system out of the bike loom and use a much more efficient R/R.
You wire directly from the Stator to the R/R - Then directly from the R/R to the battery.
Many people use the FH020AA R/R unit.
When it is done - the bike holds between 14 and 14.4 volts all the time - even at idle.
The std R/R does not charge at idle.

Is that 13v with the engine running ?So, steady 13v at the battery and 11v at the bulb holder. I'm going to do this 'loom fix' anyway and charge system upgrade. Thanks for the quick responses.
yeah sounds stuffed but with the wiring having such a catastrophic impact on the cbr's stator/rec history it just repeating itself bad wiring, bad wiring, bad wiring, first replace earth strap and remake loom wires from stator/rec to battery+ first before getting any new partsIs that 13v with the engine running ?
And does the 13v increase at all when the bike is above 2000rpm ?
Sounds like you may have lost a phase in the stator and the battery is hardly charging.
