The pump relay is immediately to the right of the regulator/rectifier when viewed from the back of the bike. It has gone again twice since I last posted about this and was informed by my dealer that there may heve been a batch of faulty relays sold. Not certain if this is correct or the usual dealer bull.
Since then I have flipped the reg/rec under the rear of the inner mudguard. I had a suspicion the relay may have been overheating from being to close to it. Since I have done this I have had no futher probs. Don't know if this is because I have got a good relay at last or it not longer gets cooked by the reg/rect heat.
Anyway I still always carry a spare relay in a zip bag cable tied next to the relay
and it can't hurt to actually get a reg/rect where it can get some cooling from the passing breeze insted of the stupid original position fully enclosed under the seat.
If you want to flip the reg/rec it quite easy. Remove the relay mounting bolts and drill down the holes through the inner mudguard and tap the threads straight through. They are only brass inserts so the jobs easy. Loosen the seat base and the relay will thread through the gap at the front with a bit of a squeeze. Refit the reg/rect underneath with longer bolts with spacers to keep the reg/rec from touching the inner mudguard and thats that.
General point - As a matter of interest my dealer said DDS would not pick up this fault and no resets are needed for fuel pump relay failure.
Hope that helps.
