test your voltages with a multimeter to see if your lights are getting the power they require & that the battery is charging.

Comment so I can find this again!

Stoked on the way my MAX harness install turned out so I figured I'd post a pic..

pm and payment sent

Good job mounting the components. Everyone should pay attention to that pic and spend a couple of extra minutes making sure the battery box looks like that inside.

I can't look at my harness right now but can somebody please tell me what color the 2 wires going to the coil are and which 1 is the hotwire and which 1 is the ground wire?

are they not green and black? with Green being power? May be wrong.

From the first page!!!

Front side:

#. HARNESS wire Color > OEM PARTS wire color (Notes)

1. Light Blue > Y connection into BOTH Light Blue from OEM left controls AND Light Blue front signal light (+)
2. Orange > Y connection into BOTH Orange from the OEM left controls AND Orange front signal light (+)
3. Grey > Grey from the OEM left controls (signal + flasher input)
4. Black > Black from the OEM left controls (DC + input)
5. Black/Blue > Black/Brown from the OEM left controls (AC + input which is OK to power most lights with power from 6 and some 8 pole stators)
(BUT if you have an 11p stator which has too much power to run typical headlights without blowing them, don't connect Black/Blue harness wire. Instead do a Y connection of the Black DC harness wire AND Black AND Black/Brown from the left controls so that the accessories are all DC powered, don't do the y connection here with a 6 pole or the battery will die from too much DC power draw) Alternatively 11p and AC headlights input could benefit from an AC voltage regulator as stated above in the tips/tricks.
6. No harness connection! > Connect the Blue left hand control wire directly to the High Beam (+)
7. No harness connection! > Connect the White left hand control wire directly to the Low Beam (+)
8. No harness connection! > Connect the Light Green left hand control wire directly to the Horn (+)
9. Green with female spade terminal > Horn ground (and you can use this for headlights and signals ground as well, or frame ground those separately)
10. Green/Yellow > Y connection into BOTH Green/Yellow (left and right) brake lever switch wires (level pull outputs brake light and starter relay +)
11. Black > Y connection into BOTH Black (left and right) brake lever switch wires (+ input to brakes)
12. Yellow/Red > Yellow/Green from the OEM right hand control (- output to starter relay)
13. Green > Green/Yellow from the OEM right hand control (- input)
14. Black/White > Black/White from the OEM right hand control (- output to CDI)
15. Green/Black > Black/Red from the OEM right hand control (- input)
16. Red > OEM key switch MIDDLE terminal (battery + input)
17. Black/White > OEM key switch LEFT terminal (+ to IGN Relay)
~ 90 degree black and red boots > bolt each one to the starter relay (does not matter which side is red or black. Tape this up good so it does not touch any thing.)
~ Black Rubber Boot > bolt down to negative battery terminal (Frame ground - make sure this touches the bare aluminum frame, you can bolt it down using a battery frame bolt)
~ Red Rubber Boot AND fused orange wire ring terminal > bolt down to positive battery terminal
~ Plug with Yellow/Red and Green/Yellow > plugs into starter relay 2 prong plug
~ Dual plugs 4 and 2 prong > Plugs directly into CDI
~ 4 and 3 prong large plugs > Its already plugged into rectifier

Thanks for the help, but I didn't see anything in your post about coil wires. I called Dan and got the answers I needed from him.

anyone having an issue with the electric choke? i cant seem to get mine working

how can you tell it is not working?


A common problem with gy6 carbs is the autochoke sticks open only way to fix it is to replace it or better yet remove it and jbweld the holes shut. Removing it makes tuneing idle alot eaisier and your ruck wont let you sit when it gets stuck open.

I agree. I blocked off the autochoke as soon as I got my harness wired up and the enginecan running. It made a world of difference.

I blocked mine off as well and did not wire it in.
Mine Idles way better.
I used to have to drive it a bit then it would idle ok.
Now after one start it idles great right away.

Woo Hoo!!! got my harness in started to tuck it last night then realized I had better make sure that it runs first bfore I go through all that trouble. So will be hooking up tonight just what is needed to get it started and running tonight

Are there any down sides to removing the auto choke?
