Hi everyone. new to this site. Reason im on is this. I have a 110 chinese ATV i believe its a coolster. Had the remote kill switch on it. No fob so i removed the box. No key either ( no i didnt steal it lol) my buddy gave it to me for my kid. We are active duty Army. Problem was he lost both the key and the fob when he PCS's outta the state Colorado. Anyway thats why i eliminated those two features.
Ok here is the issue. Had a no start, replaced the batt, now it turns over had a no spark. And this has been my mouse trap for 4 days all day. Im loosing my leave days trying to figure it out. Lynn Edwards this will need your attention please. I have done EVERYTHING to resolve the no spark. New ststor. All values are within range as to the flow chart described earlier out of stator, 5 pin CDI the (new performance kind with a led light on it) i replaced with a new one. Tested the regulator and its just fine as for resistance ect. But that wont stop my no spark. I then went through every wire and completly removed all wires for lights and things indont need. Its now just bare min. I replaced every ground wire with new wires. Soldered everything and heat shrunk protected. I dis the big three ground trick i learned long time ago as a mechanic. I have solid ground from frame engine to batt to wires in multiple spots on frame and engine over board on ground but thats good. Ok so. Im getting a weak spark at the plug most the time UNLESS i hold the CDI box and move it around a little bit. (This is the old CDI not the new one) this sometimes makes the led light on the CDI come on. And then sometimes the atv starts up and puurrs. Iv only got it to start a hand full of times btw. So naturally i think loose wite and or bad cdi. Thats when i bought the new CDI same brand 5 pin and inspect wires one more time. (Let me stop there and remind anyone who can help me, the bike started up and ran great) so completly re vamping and re doing the WHOLE wire harness worked) ok so i inspected the connectors at the harness the decided to inspect every connector again pulled them all out if they looked even slightly bad i replaced, crimped, and even soldered then to connnector to be safe (over kill again lol) but its a goid piece of mind. Anyhow. Bought the new CDI and pkuged it in. NO SPARK! I was sure this was it. Put the old one back on and same as before woulf try to start but only if i wiggled or touched the cdi box or wires coming right out of it. Got it to start again doing that. But died if i wiggled the cdi again. So i went back got ANOTHER cdi thinking it was bad. But before i left i asked the guy to ise that same cdi in his bike her had there same model and cc fired right up. Left with another new cdi but this time the stock one. But just like the last one nothing would try tonstart if iwiggled it a bit while cranking. SO.... I know everyone is thinking he wiggles the wires and cdi while cranking and gets spark. Its bad wires or something loose or the CDI or BOTH. Iv done everything tonthe wiring harness toncheck that. Beep mode on the multimeter to every wire theough whole harness nonissues at all. So why doninonly get a somid spark when i hokd the cdi box or wires right near it? PLEASE HELP iv spent 4 days on this all day. Found nothing online that is helpfull besides all the stator values and cdi resistance ect.
