i think i got the wire figured out, is this a DC-cdi or AC-cdi i need? It had 5 wires on the cdi side after i pulled the tape back.see if this is correct from the drawings I've looked at. Black/white- Ignition coil Black- Ground/Thermo element i guess motor temp Green- Ground/ shows alarm system Blue/white- Trigger coil Black/red- Magneto
From what I see there are more than one circuit in that bundle. This is a AC type CDI
Black/White = engine kill from key switch and engine kill switch on the handle bar Black/yellow = Ignition coil feed Blue/white = trigger coil Black/Red = AC feed from stator to CDI Green = ground to CDI and other components, sometimes a CDI will have 2 ground wires.
Some of these wires you may have to open up the scooter and trace their origins. You have other colors that generally mean this
Red = 12VDC from battery to key switch Black = 12VDC from key switch with it in the on position Green/Yellow = 12 VDC feed from brakes when applied to brake light and starter relay
The others could be to an alarm or even to headlights or other things, got to find out where they go?
Of course you are going to have to get a new ignition switch and with some pictures and wire color descriptions we can get these simple things going. I have a wiring diagram presently of the 50cc Aargon 2T and if it is the same we can use it, if not then we'll improvise.
1. Red/white wire out of left handle bar column is on the old harness. I tried to trace it on the old harness but its been cut about 5 inches from the connector. As its coming from the left column could it be just for lights as white and brown/white goes to the head lights and I also nees to find a blue wire that goes to the head lights too.
If it goes to the left side it is one of three things, headlight feed to the dimmer switch, horn or blinker. Only way to know for sure is to open the switch assembly on the left side and see if it is there is indeed a red/white wire?
2. The only place I can see another pink wire on the new harness is the one that's wired to my cdi.
You got to remember you are trying to make 50cc harness work on a 150cc scooter so this pink is a odd color on the CDI and here is the location and normal colors on a CDI:
So in this case if you look closely at the pin out in the image you will see the black/red, blue/yellow and the black/white are wired correctly on your CDI in your picture. The green/white and the pink even though 99% of all ground wires are green need to be hooked up to the battery negative and if green in your harness is actually a ground wire then they both need to hook into it.
Wires are as follows:
Black/red = AC feed from stator to CDI Blue/Yellow = pulse coil feed wire to CDI Black/white = engine kill wire from key switch and engine on/off switch on the right handle bar. As I stated the Green/white and Pink will need to be grounded.
Do you own a multi-meter with the ohms function? If so do you know how to check wiring with the ohms setting? If so you can easily verify the pink wire on the CDI is the same loose pink wire on your harness by the battery. In fact one can verify any wire from one end to the other.
3. No this wire comes from the electric start button. The wire has been changed to a red/white but by the looks of it inside the column it was originally orange
Ok if this is the case then it will go to the yellow/red on the starter solenoid relay and if it comes from the start button the other wire to the start button has to be a ground wire.
4 & 5. 4 is where 5 connects, 5 is all the electrics for the right column. Yellow/red, green, black/white, red/white, green/white, black, brown/white and brown.
Yellow/red = start button wire going to the starter solenoid relay Green = ground Black/white = engine kill wire going to the CDI, it may splice into the same color wire from the key switch
The other 3 I am not sure but will ask this? Does this scooter have a on/off headlight switch and a dimmer switch or just a dimmer switch?
6. Yes white goes to the stator. Its a new r/r but its exactly the same as the old one on the bike. What should I do with the black?
White will be the head/tail light feed wire and these lights should only work with the engine running. Black should be a 12Vdc wire with the key on, do nothing with it unless you plan on adding a accessory?
7. Does that mean my ignition has 2 ground wires?
8. This is my cdi wiring. Top of 2 pin connector is red/black. The bottom is black/white. On the 4 pin connector top left is green/white, underneath is black/yellow, bottom right is blue/yellow and top right is pink.
When you say flasher switch are you talking about the little switch on the left hand switch assembly that is spring loaded and turns off when released? If so this is called by the Chinese as a passing switch that when pressed gives 12Vdc from the battery to make the high beams only get brighter. The idea is to make the vehicle in front of you notice the brighter light so they see you are coming around them.
Since you have said you have checked the bulbs and connections we now have got to start looking for voltage along with any possible bad ground issues. Question did this happen when you were riding down the road all of a sudden or did you just start it up and find it that way? Reason I ask is a bad ground or still even a bad connection is the number one reason if it just did this all of a sudden riding down the road.
So let's do this I need you to start the scooter and take a volt meter and take a voltage reading on the battery with the scooter idling. Then take a reading with it revved up to say 5k rpm or so. Why do this? This tells me if the stator and R/R are good provided there are no bad connections here. If you tell me I've got good voltage at idle and even better with it revved up then we know that we do indeed have a gremlin other than a bad stator or R/R.
If this is the linhai then you should not have a fuse box and the head/tail light circuit along with the instrument panel lights are on the same circuit.
Get the battery readings and get back to me and we'll go from there.
#1 Red/White is generally a wire that comes off of the key switch and /or engine run/off switch. It would go to the CDI so when the key is in the off position it grounds out the CDI thus killing the engine. It may go only to the key switch or engine kill switch or split and go to both. Is this a original wire on the old part of the harness? If so then trace it out so we can be sure. White can be to a lot of things including headlights, again is this part of the original harness?
#2 I'm assuming the pink is part of the new harness you bought? Pink is generally a accessory wire like to a tach? Where does it come out at the other end?
#3 Same as answer on number 1 is generally a kill wire to the CDI. Is this the same wire as #1 and just the other end? Can you use a meter to check it out using the ohm function of the meter?
#4 &5 $ looks like the CDI plug according to the number of wires and colors. 5 looks like start button wires and other things? Can you tell me all the colors, hard to tell in the pictures?
#6 pink would go to white if whites goes to the engine stator? Black is generally a 12Vdc wire from the key switch and is hot only with the key on. Is the R/R original or a new one?
#7 Green is always ground or at least that color green and runs to a variety of things including the key switch.
#8 Part of it looks correct but you asked about the pink wire, is the 4 plug got a pink wire? I need to know those colors for sure hard to tell with picture.
