Hey all I purchased this 2007 sunl 250-22 last year. It had run well, if a bit rough, for most of last summer, and this spring. It was a bit finicky at first but after an oil change, new spark plug and radiator flush it seems to be running well except for the cooling fan. I gave up on the heat sensor that plugs into the radiator, after replacing it with out any change, and installed a witch bypassing the sensor under the seat. Recently it quit during a ride into town. I had gone perhaps a half of a mile when the darn thing up and quit on me. It was running smooth then when I pulled up to a stop at a one lane bridge it was running one minute then the next dead. The engine quit all gages died no indication of power. I have currently tried the following:
1. Trickle charged over night
2. Replaced the starter coil
3. Replaced the solenoid
4. Replaced all the fuses & fuse box
Nothing changes. I turn the key and no power. I replaced the ignition coil, and the solenoid no change. I noticed if I put a jumper across the solenoid the starter tries to crank, but it doesn't quite turn over. I noticed when I replaced the fuses that some of the wiring between the wiring harness and the fuse box was melted, so I replaced the furze box. I am still not getting any electricity to the starter or the gauges. If some one could give me their opinion as to if I should replace the entire wiring harness or the cdi box and if I should try to find a sunl part or use a rocketa instead, as most of these are basically the same scoot with different branding.
