Hey all - need advice on electrical issue By stevensonrc (Read 583 times)

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 gages. 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.

Well if you jumped the Solenoid and the battery had enough juice it would spin the starter.
If you have a Volt Meter check what the battery reads just sitting there. When you jump the Solenoid you are bypassing everything and sending the battery juice directly to the starter. So it barely turned the starter I think your battery is shot.
Try jumping it off your car battery(BUT DO NOT HAVE THE CAR RUNNING).

get a test light , put the aligator clip on the positive side of the battery . Poke the negative side of the battery , make sure you get it to light . Then poke the engine followed by the frame .
