I’m not too enclined on wiring on these things but I have no spark and the starter switch isn’t working and when I test o/w on the ecu and a few others I’m only getting 3 volts. Which I can’t make much sense of it. I know for sure the battery is good the gauges turn on when I turn on the key. Another thing is the fuel pump doesn’t prime or work, I get voltage to the wires when not hooked up but as soon as I hook it up the volts go down. I know for sure the fuel pump works because I hooked it up to the battery and it ran. I had the bike in running shape and then all of a sudden this stuff started happening, it gets extremely confusing. If someone could tell me if it’s an ecu problem or the rectifier or stator that would be great.
