But you didn't say what you jumped it to. Your car? Your charger? I'm not getting important answers to simple questions.

As far as the motor locked up - take a side cover off, find a hex nut on the crankshaft and turn it with a wrench. Does it turn?

13.26 volts is a little high for no engines running (car or quad), but you would expect that the voltage at both sides of the jumper cables would read the same without massive current flowing in the jumper cables causing a voltage drop through the cable.

So let's review what you're saying as I see it (you have been very thin on reporting details):

You take a pair of jumper cables and connect you quad to your car battery (the car you start up and drive to work every day, right?). You try and start your quad and it sucks down the voltage measured right on your car battery terminals to 5.3 volts?

In other words your teeny little quad sucked down a working good car battery to 5.3 volts? I don't believe it. You certainly did not do this test as per the above description.

If you still think you did this test then you did it wrong. We need detailed information on what you did.

yes everything was done exactly like you told me to and it still drags it down that far with it hooked up to the car battery

and the starter wire and starter gets hot

i jumped it from the car

i took the side cover off and found hex nut on the crankshaft and turned it with a wrench and it did turn over

Was it easy to turn over by hand??
I ask this because, All jumper cables are NOT created equally.
It is possible that the clip only have 2 or 3 strands of wire making contact. That would restrict voltage and cause the starter to get hot.

With all the weird stuff you say is going on, then may be it is time to look at things taken for granted.

There is a lot of info here that doesn't add up. More than one problem, or maybe measurement error, or both - it makes no sense at this moment...

OK, your starter motor doesn't turn, the cables get hot and so does the starter. If you take out your starter motor and use your jumper cables to power it up off the battery directly - positive to the starter input post and minus to the starter case. Does the starter turn outside the engine all by itself hooked up to the quad battery?

Also do the same with your old starter motor. When you jump it does it turn?

Also try using the car battery to directly power the two starters.

On both the starter motor tests measure the DC voltage at the battery while the starter motor is hooked up, and also measure the voltage at the starter motor (input post to starter case). Report those measurements.

Bad jumper cables are definitely a possibility for some of the reported symptoms, but a bad connection somewhere in the jumper cables (like just a few strands hooked up) would cause the jumper cables to heat up - not the starter or the starter wires. And the heat would be concentrated right at the bad connection where the wires neck down to the few strands.

Bad connections are the same thing as resistive connections. Dissipated power (i.e. heat) is proportional to the current squared times the connection resistance. So bad connections that are passing substantial current will also be hot connections.

Lynn, My idea was 12 volts to the starter with 6 to 10 amps.

More than anything my post was to maybe get everyone to stop take a deep breath and enjoy trying to troubleshoot this problem and re think what has been reported and if there is a better way to explain what is happening.

From what I get out of all that has been said is it does/will not start with any starter or any battery or charger. BUT the engine is not froze up, locked, seized or otherwise prevented from turning over. So all the physical laws that we know and use do not apply to this one bike. keltikayla seems to have knowledge and use of the English language so nothing is getting lost in translation, however mechanical and electrical phases may be throwing them. ( like the people that say it will start but not catch), terminology might be thought to be one thing but is something different.

I am sure that something is just not being put into the correct words. And basic description is being distorted.

But this is just a guess on my part. Maybe this 4 wheeler is from some other dimension.

Don't ever think people don't appreciate what you do.. We Do

Does it turn over really easily with the sparg plug removed?

Is it possible theres a bit too much oil in it? i put about 1/4 litre too much oil in my 250 last time i filled it and it was crazy hard to turn over. I think it was hydrolocked. Drained a couple ounces of oil and it turned over and started fine. I did't have a voltage drop to 5V tho.....

Did you try hooking the car batt directly to the Starter and bypass the wires and solinoid?

yes it was easy to turn by hand just got a little stiff when the compression came up

yes both starters spin when they are hooked up to the quad battery and also the car battery

at the starter it reads 8.25 with the sparkplug out it turns over slow for about 5 seconds the stops and at the battery it reads 12.86 then when i try to start it it drops to 8.56

the jumper cables i am using are from work and we use them to jump semi trucks so i dont beleive the could be the problem

it turns over about the same but without the compression stiffness

i tried to hook the car battery directly to the starter and bypass the wires and the solinoid and it did the samething turn over for a few sec and then stop
