I've run into the same problem it sounds like many of you have, the rectafier. About the 4th time i changed it out, it really went out with a bang, ended up blowing every bulb on the bike, frying the ecu, and worst of all my guages don't work now. I have since fixed everything else, but it fryed two resistors in the tach and the speedo. If anyone has pic of the back of there guages it would help greatly, when it fried the resistors it made them unreadable to tell what value they are.
