    The problem seems to be a charging issue

    This a gen1 ? The bullet Diag wires you are looking for are under the rear r/h side near the mesh on a gen1.

    If it's a charging issue you need to measure the input from the stator into the reg/rec

    They should all be pretty much the same output at tickover and almost identical again at 4K rpm also. Measure all three across one another with a multimeter. If one is different or all different the you stator is burning out. Also check input into battery in case the reg is faulty.

    Yeah, 2004 to Years have that stator burn out problem, lots of good info on tech forum. If your brown connector from the rectifier is fried, that's probably the problem but do the test. I have an 03, so got lucky with this. Good luck man, keep us posted

    Hi guys , I have solved the effi light issue!!!
    It was a brown connector between rectifier and stator ! I cut the wires and soldered them
    And the light disappeared ! Although Iím not happy with the voltage output !
    It ticks over at 12.7v and at 4K , barely reach 13v
    Checked the stator output and and itís pretty much the same across the tree wires
    And rectifier should be ok too !!any tips ??
    Mann thanks

    yeah that's low on the voltage, mine goes to 13.5, should be able to hit 14 or so. The riders that do the aftermarket stator and Mosfet rectifier get over 14 volts. The sprag clutch might start grinding if the bike starts to have trouble starting due to low voltage, I wouldn't hold the start button for too long. It's not just us, some japanese bikes have same issue as does the Harley Sportster 883.
    Let us know what's going on. There's a real good read on this forum if you search Rectifier/Stator Problem. In any case, I love my RSV and most likely will never sell it. I've sold all the others, this one I'm attached too for some reason.
    Ride safe, I almost moved to your side of the pond.

    I agree is a lovely bike ! But gosh it frustrate me ! Sometimes is nice to go out without worrying about breaking down . The immobilizer is fried ! ( currently looking for someone with a master key so I can fit a second hand unit )! Voltage is low ! Sometimes it misfires 😱😱😱😱although the misfiring could be due to the Lowe voltage . I will go and replace the power cable from battery to starter and see if it fixed the issue

    Yeah man, once you resolve this it probably won't break down on you.
