YY250T Missing Module Electrical Issue... [huh] By vyazovich (Read 1,494 times)

Hello,

I really need some help, I bought a JMstar yy250t scooter that had a missing ignition... Here's the story: The lady i bought it from said it was her brothers, his key broke in half in the ignition so he took it apart to replace it, he ended up in the hospital due to an illness, and passed away...

I have replaced the ignition switch but i am unable to start/power on the scooter all the way, what i mean by this is that only the horn will work and the turn signals blink front and back. The brake lights don't work when pressing the levers, head lights do not come on, unable to start as it seems dead... the clock does work and the battery has a good charge.

I have taken all the plastics off the scooter to check the wiring for damage, following some guides here on this forum i tested the voltages to the CDI, Rectifier, etc... i have power on all black wires, and most red wires... and seems all green wires are grounded out...

Last night i have discovered a 9-wire plug under the speedometer that was just hanging loose... I do not see where to plug it in and am thinking that is the problem... i have tested the plug using a volt meter and here are the results:

Wires:
Black - 12V +
Tan - Rear Tail Light
Light Blue - Rear Tail Light
Green - Ground
Red/Yellow - 12v + when pressing the brake lever
Red - Don't Remember
Brown/White - Kill Switch
Black/White - Unknown

the center wire powers when pressing the lever, two wires go back to the tail lights, one wire goes to the kill-switch on the handle bar, one wire is power.

I have found two other plugs that look the same and those come from the handle bar switch's one for the left and one for the right...both are plugged in.

Can anyone tell me where this is supposed to be plugged in if at all. I have looked for replacement modules, but the only 9wire plug modules i find are for the handle bar switch's. I'm thinking it might have went to a alarm system? does anyone else have this plug? maybe can send me a pictures of what yours is plugged into? maybe i'm looking the wrong place and i need to test/look else where...

Thank you in advance for taking your time to read my post and provide any tips/hint/help.

The easiest way to fix this is to replace the ignition with a new one.
Maybe $20 and a couple of hours and you're done.

Wow.. thank you for the fast reply... I have purchased and installed the new ignition switch already, it came with the keys n all... when i turn the key all the way to the run position it seems dead as described above... i was hoping it was going to be that easy... lol but it's not. Do you have this same scooter by any chance?

[Guitarman]

Looks like mine. Got a picture of the bike?

If it's the same as mine, there is a connector inside the 'dash' box where all the speedo and lights are.  That's where your plug goes.

i would imagine that you are on the right track with the 9 pin plug,,,must be an alarm system,,,,turn the bike on and probe test the pin block to see where you get power and then chase down the other wires coming into the block ,,,maybe you can do some jumpers that will get you on the road

[vyazovich]

This is the only pic i have currently... i'll take some better ones when i get home...

[vyazovich]

cyborg Thank you so much for the replying so quickly... i tried to jump the wires to the tail lights but would get a buzzing sound around the battery area... my guess is that i'm send to much power to the taillight... it did not light up the bulb btw...  i decided to stop not to burn anything up... lol

[cyborg]

i think you must have jumpered the starter solenoid,,,i would use a multi meter tester set on dc voltage,,,you can get them very inexpensively at any home center or harbor freight

[cyborg]

also what you may do is search the bike and see if you have a blown fuse,,,check the bulbs while you're at it

[vyazovich]

cyborg, i have checked all the fuses i could find. they are all good... i'll have to test the rear bulbs as that i did not test them... i also have one missing... not sure if that would cause an issue but i will check... Do you have a module next to your ignition wires?

That looks like the Alarm and remote start plug. Looks like someone took it off.

So try this:

Find the alarm/remote start module and find the white plug for it. Unplug it from the wiring harness then check the wire colors if you have a Brown/White and a Black/White wire or 2 Black and White wire or a Grey and a Pinkish wires in the harness plug join them together with another wire. .

So the wires your looking for To JUMP are:
1. A Brown /White and a Black/white wire
2. Or 2 Black and White wires
3. Or a Grey and a Pinkish wire


If the alarms have a fuse just remove the fuse and leave it plugged in.

Alleyoop,

Thank you so much!!!

I will try what you suggested...

[Alleyoop]

Maybe these two:

Which every one works let me know and I will label the plug and add the pictures of your plug and JUMPed wires to the TECH SECTION to possibly help others with a similar problem. Not all Alarm and Remote plugs have the same color wires so it could change from remote to remote on different scoots.
Thanks Bro

Alleyoop Thanks... i will try when i get home... do the headlights turn on when it's running?
