First off hello and thanks for having me. I had to venture out to different forums because the ones I was in didn't really have any active members who were able to help or even respond. Now before anyone starts throwing stones at me please forgive me I drive....eh... I drive...uh I mean I drive a scooter........ sorry but I do for now
I know it's not the same as a rocket but a lot of the parts are very similar from motorcycles to scooters such as the Yamaha Lean angle sensor. I believe Yamaha motorcycles carry the same one as Zuma 125 scooters. I have checked everything in the ignition circuit diagram, replaced stator and ignition. Tested the kickstand sensor, engine stop switch, main switch and main fuse. I have verified everything checks out I even have ground to chassis so I am down to 3 suspects. 1.)ECU 2.) Lean Angle Switch 3.) Some type of short in the wiring. 4.) Just thinking about it maybe I have a voltage drop issue.
I am not the type to quit but man this scooter has been kicking my ass.
I checked my lean angle sensor for voltage and at level it is around 4 volts and 45 degrees or more it reads at .8volts. The service manual says anything less than 45 degrees should read .4Volts and greater 1.4volts but the sensor is clearly adjusting voltage as its rotated and I don't have much confidence in the numbers I always see different specs other than what the service manual calls for and the part still works. If anyone can share any insight I would appreciate it I am pretty desperate at this point thanks.
