I have a 2004 Triumph Daytona 600. There is a problem that when a large electrical load is put on the bike, ie hitting the brake lights, fan comes on, headlights on bright, that the Speedo display cuts out and resets. After taking the bike to the dealership, there were no problems found on the wiring harness for a short, a plug was replaced, battery replaced, and the charging system gone through with the generator rebuilt. After a few weeks the problem started again. The dealership told me to replace the ecu. I bought a much cheaper used ECU on ebay. So I have two questions. Has anybody had a similar problem? And to replace the ECU do I need to do anything special, in otherwords can I just swap them out?
