are you thinking of the battery being dead

Not by his description justbuggin because he said he jumped the starter relay and it would start.
But they ohmed the key switch functions and said bad switch but myself even "if" the fuse is good I would want to see 12Vdc on the red wire to the switch at the switch. If you set the meter to read DC and test the red wire to the green wire on the key switch and read 12Vdc+ then that tells you 4 things, red, green wire, fuse are good and you are getting voltage to the key switch. Also this scooter doesn't have a diode as stated by you know who and it does have a side stand kill switch and he made the statement it doesn't. If this is so then it appears it has been tampered with.
He never said if he bought this scooter new or used? You see to ohm is all find and dandy but the true test is voltage. Been around a lot of crazy things on electrical and have on an occasion seen things not read write on a meter when doing a ohm check. some of depends on the quality of the meter itself but the one true thing that alwasy reads one way or another is voltage.
You see the key switch can be tested by reading DC voltage instead of ohming it. If you do have 12Vdc on the red then this is how you do it. Set your multimeter to DC volts, again you have to verify the red wire is hot;
Test the red wire to the green wire with the key off, if you read 12Vdc+ then you know the red and green wire terminals on the key switch are ok, the red is passing voltage even through the fuse and green (ground) is also good.
With the key still in the off position test the red wire to the black/white wire terminal on the key switch, if you have 12Vdc then the black/white terminal on the key switch is also good.
Now turn the key on and test the black wire to the green and if you have 12Vdc+ then the black wire terminal on the switch is also good.
Lastly with the key on test the red wire to the black/white wire and you should read no voltage, if you do then that function of the switch is bad.
By reading voltage when testing something like a key switch you cover all avenues including "do you have DC volts?"

It's tough for sure! LOl But if you know these scooter diagrams ..........and another scooter like it you can figure it out.  |

Oh my my, new key switch in and still no go? Didn't I mention voltage? BTW it's not a ground wire either. And the mysterious stuff works when the relay is jumped? Oh well back to the multimeter!  JR  |

I'm not sure what you saw in the pic . I did notice it looked like 2 fuses in the holder .

It's not just the picture John but I will tell you what I know by looking at the picture. In the picture there is:
alarm plug with the jumper
ignition key wiring system, four wires
fuse holder on black wire from ignition
Now I'll tell you what I know by what I read;
He said he could jump start the scooter so we have a good battery
He said he had no accessories and could not start the scooter so we have no DC power getting to the starter relay via the brake circuit, no horn and no turn signals, point blank we are not passing 12Vdc to the scooter circuits especially the starter/brake circuit
He changed the key switch, was no help so we know that's not the problem (never believed it was)
Now by reading also he said he had good fuses at the battery and up by the key switch (black wire in picture) but are they good? He has a picture witrh the meter he's using and it's set in the diode position? Not being rude but by looking at the typical Chinese fuse holder again in the picture are the cheap fuses really any good and like Chinese holders that if I use I soldier them to make them work good are they making good contact?
We know he has a good battery and 12Vdc but by again reading I see no mention of I have 12vdc to the switch on the RED wire at the switch, period!
Also we know by looking at the picture that even if he does have 12Vdc on the RED wire at the switch we can see the fuse holder on the BLACK wire off of the key switch, if this is bad NO DC POWER to the brakes/starter relay circuit.
Also the why is it working when jumpimg the starter relay? That's all for you to solve, no mystery to me.
Time IMO for this fellow to move on?

Just saw his post TV. Glad he's running but not buying it. The stuff works when crossing the starter relay is a dead givaway.
Also he could jump start the scooter with a screwdriver, remember? bad rusty ground on the frame would not allowed a good enough circuit for it to start, come on TV you know better than this? In fact with all the amps the starter pulls it would take a very good ground for it to even jump start across the starter relay.
Not buying it for one minute, in fact I still say he didn't have power to the switch to begin with.

terrilee it turns out that he had a dirty ground connection from the battery
