I have two 2008 jetmoto's one runs great. lights will come on bright when key is on without running....

other quad came with a blown fuse , one blown head light, and leaky battery, which is no good.

i replaced battery and fuse ... removed blown bulb. the other headlight bulb will come on bright only when i idle very high.

also doesn't seem to have the performance that the othe quad has, seems to putter when pinned. any ideas?

 

Check all the wires at the ignition cylinder(key switch), and check all the wires at the CDI harness clips. Voltage regulators are cheap and I would switch your out for a new one.

it is easier to remove the fenders to have access to the wiring harnesses. You will need a volt/ohm meter

 

. I have no spark either I had verry little once I guess but my kill switch only flips up or down....I think. I tried pushing...but no push

 

And the paper work and owners manual are thin to win. Cheap unhelpful crap as are the dealer's who sold it to me out of michigan. It was over three weeks late and they are less than helpful wen called. Is this a better business bureau thing? Cuz sounds like alot of people w same problems . I'm getting ready to take a 13 hour drive soon and cram it up there u know what

 

[QUOTE=Bill-Nevis;2890732]I am new here. And I have the same problem u do lol and isn't seem to find the problem and had several mechanic look at and nothing I wish I knew what it is my self 1,800 toy just gone now til I find the same answer u do it sucks not be able to ride if we all cant located the problem

This is my 150cc Tao Tao atv when the key is off I have power to my cdi but when I turn the key on I have no power and no spark everything is wired correctly but my coil has a green ground wire and a yellow and black wire that is supposed to be a positive but turns into a ground when on the coil but when I check for power on the yellow and black wire at the cdi it showed no power at all for that wire. Please help !

 

I suspect you are a bit inexperienced with using a multimeter as you are bound to get a negative reading at the black/yellow because it is earthing through the coil until the engine is turning. There should be no positives at the CDI with ignition off, or on for that matter if it is AC CDI which, from posts above, was never cleared up by the people Lyn was trying to help. Go through the tests in Lyn's sticky "help diagnose stator" at the top of this section. If your machine follows convention, it will have a black/red to CDI. On AC CDIs this comes from the stator, but on DC CDIs this comes from either kill switch or ignition switch. There will be a black/white too but this can be used on both AC and DC systems

 

The red/black wire comes from the stator so it is an ac cdi

 

It just has no spark and I am confused I changed everything

 

As I wrote above 12v positive DC on any wire going to the CDI means a fault, and may well kill the CDI. Someone put a bare bones wiring diagram up last week https://atvconnection.com/forums/chi...lp-wiring.html if you have rewired the bike using a "universal" loom, it should follow this diagram, so check out your ignition wiring to make certain it does, then do the tests in the help diagnose stator sticky to ensure the new stator and other components are not faulty.
