Hi all,
My 1998 ST2 leaves me stranded on the odd occasion by developing a flat battery. There is no pattern to this. I've done 4 days away camping and had no problem. This week, a 4 hour trip to Scarborough & home again left me stranded at my local petrol station after refuelling.
I always ride with lights on and no electrics ever fail while the engine is running, so something is working. It had a new battery last winter (which is only 2,500 miles ago).
The bike sits on a trickle charger so always sets off with a full battery (this is confirmed by the status lights on the charger).

Now I know that the 98 model had a particularly poor charging system, but I seem to remember reading somewhere that the system can be upgraded by the home mechanic by fitting better grade wiring to some bits, but I can't remember any details.

Any ideas will be gratefully accepted.

Mike Chadwick
