I have an '07 Kazuma Falcon 150cc.

That will not turn over.
Battery fully charged
Turn the key on, press the starter...NOTHING.
Brake lights work
-12 Vdc on BLK and RED at Key switch.
Stator is marked SM060415

I was a Laser technician so I can use a multimeter. anyone interested in walking me through a trouble shoot?

Let me know what other info you need to help.

Thanks in advance.

does the solenoid click when you hit the start button? have you checked the voltage of the battery when you hit the start button?
try this: turn the key switch on, take a screwdriver and jump the terminals on your solenoid. does it turn over/crank?

 

i'm not real familiar with kazumas, do you have an inline fuse between your battery and solenoid?

 

Fuse is good.
No click from Solenoid.
Will try hot wiring solenoid in am and let you know how it goes.

Thanks for the support,
PH

 

define hot wire solenoid? do you mean jump it with a screwdriver? also, check the voltage of the battery while cranking the starter, whether or not it's with your button or jumping the solenoid. let's see what that says also.

 

Jumped Solenoid and it started, so I assume the Solenoid is bad?

Next problem;
starts but wont stay running, even at idle...
On to the carb.

 

Am I wrong assuming this? Could it be the starter switch? If so how do I test?

Thanx,
PH

 

i'd say the solenoid switch is bad, as far as the starter switch, we'd have to wait for LynnEdwards or one of the electrical experts to give advice. you are correct moving on to the carb/jets, it needs to be cleaned........

 

when cleaning your carb, make sure to pay attention to detail. look it over as you take it apart. inspect as you go, clean, clean, clean. use a carb cleaner aerosol. use compressed air, use a fine rodding out device. i use an oxygen/acetylene torch tip cleaner pack. usually the smallest 3 will work. the orifices on the jets and down the jets' throats(longitudinally in the center) have to be clean, make sure to rod out each hole and see daylight through them. use these generic pics: see the orifices scattered throughout the jet?

granted, your jets may not look identical, but you get the drift, right?

holler back, after you get the carb/jets clean, maybe by then the electrical experts may have replied for testing your switch. if not, you'll probably get by with just replacing the solenoid and that should fix you up.....just make sure your battery is hot/charged up and ready to rocknroll.......

 

Re: Starter solenoid:

You say the solenoid does *not* go click with the start button (while the brake light is lit up), and the starter turns and the starts up the quad when you short the two big screw terminals together.

If you look at the solenoid you will find that in addition to the two big screw terminals there are two small wires coming off the solenoid. If you apply 12 volts across these two small wires it energizes a coil inside the solenoid, which makes a magnetic field which sucks down a steel plate, which shorts those two big screw terminals together just like you did by jumping it externally.

So the next test is to go through the start process (ignition on, brake light on, and start button pushed) and simultaneously measure the two small wires to see if you have 12 volts across them. If you do you solenoid is bad (although this is an uncommon failure mode).

If you don't have 12 volts across the solenoid then you have a bad start switch or wiring problems. There are two ways the quads are usually wired. I'll start from the brake switch output side since you say the brake light lights up (so this eliminates the fuse, ignition switch, and brake switch as possible causes since the brake light lights up):

1) Brake switch output side goes to one side of solenoid (small wires).
2) The other side of the solenoid goes to the start switch.
3) The other side of the start switch goes to ground.

or...

1) Brake switch output side goes to one side of the start switch.
2) The other side of the start switch goes to to one side of the solenoid switch
3) The other side of the solenoid is wired to ground.

In both of the above cases not that 12 volts gets applied to one side of the solenoid through fuses and switches, and the other side gets grounded sometimes permanently, and somethimes through a start switch.
