My kid has a SUNL SLA-109 (yr 2006), their cousin turned it up & washed the mud off of it, & ever since it won't start, it is not getting spark, the coil is not getting any battery positive with the key in the on possition, can anyone tell me where i can get a wiring diagram for this little four wheeler? the coil wires connections at the left frame rail were touching bare metal, i corrected this & still no change, any advice would be welcomed.........

 

this is one reason why setting up a chinese atv is to take liquid electrial tape and cover all the connectors with it, you wouldn't had this problem. the very first thing to do is on the handle bar switch is remove it off the handlebars and blow it out with compress air, then spay wd40 in it, if that doesn't work then you need to remove all the plastic and start removing the electrical connectors one at a time and spray wd 40 in them, that should work if it's water related, when and if you do get it running buy some di-electrical grease, put it into each connector and handle bar switch, then cover all the connectors with liquid electrical tape and you won't have this happen again, i have done this with each chinese atv we ever owned and we power wash them without any starting problems, so i know it works. one more thing if the coils wires were shorted out on the frame did you replace the fuse ?

 

thanks for the advise, I'll check out what you suggested, I did find two fuses (one glass & one 10 amp blade fuse) both were still good, thanks again..........

 

it might be your cdi box.
