Gen 1 Fazer Electrical problem.

[g5guzzi]

Does any of the wires you altered connect some how to the ecu.If they do you may have damaged it .Dose'nt take much to do this.If the problem persists I have an old ecu from an 03 bike which is ok except for the part which turns the lights on.You are  welcome to it if it may help you sort your problem.The numbers on the ecu have to be a match.The one I have is 5lv-82305-40.  131800-8310.  12v  tndf71    denso.I do hope it is not this but if you accidently put a live feed down an earth near  the ecu it may share the same earth and get damaged.Some vehciles store the oddometer readings in the ecu.
