People s200 / 2007 kymco s200 electrical starting issue, thought it was light controller
« on: July 19, 2024, 07:35:12 PM »
Hello
I just made my account because I have already purchased one part which I was sure was the issue(The Light Controller) but after replacing it is not.
Long story -
So I got the scooter from a friend to work on but it was not starting. He replaced the battery and the starter solenoid and it was still having issues. At first I would get lights and then when pushed the starter the lights would go dim and then the scooter would never recover from the pull of starting once or twice. So I started checking all the electrical common stuff. I got a clean ground to the battery and the battery is in good shape. I put new fuse in where they needed to go and when I started checking voltages the main plug going to the key ignition tumbler is only sitting at 11 or 10 volts. When I go to turn on the bike now i get no lights or speedometer moving when key is turned on and the bikes power continues to site below 12volts and i get no cranking from the starter. I noticed when I unplugged the lighting computer module from the scooter wiring harness and checked the main power plug to the key tumbler the voltage was at 12.7 where it most likely belongs so i assumed that was the issue and got a used one from ebay but once installed it was doing the same thing.
So short story is---
I have a s200 that seems to have a low voltage issue in the system when the key is off or on. I cleaned the ground checked fuses and battery is at 12.7v. I check the power harness to the key it is below 12 volts and the bike will do nothing when turned on. No horn or lights. Lighting computer was replaced but didnt fix anything. Is there anything you guys can think of that may cause the condition? Rectifier? Ignition ECU? or am I missing another ground some where? I checked all plugs and took off tape on half the harness to see if any melting happened but do not see anything.
Suggestions welcomed
Trying to not to not buy anymore parts because the lighting controller was expensive unless im sure that is what needs replaced.
Thanks
