headlights burn with key off ,regulater bad or a stator? its a 150cc gy6,and ac fired system

[sprocket]

Stator? Replace the ignition switch or disconnect the headlight wire at the switch or disconnect the battery...

[Bashan]

Yeah, it's not the stator or R/R, they wouldn't do that. As Sprocket said the switches could be bad, and you could have a short from the DC system on one of the yellow wire branches. The yellow is grounded in lots of places to the frame so any hot wire from the batterry shorting to it will light it up like a Christmas tree. Start inspecting wires and checking switches with your multi. Rich

well rich little info my dumb.... hooked the batt 2 a running diesal truck i know was a dipsh... thing 2 do before a knew it, it smoked so when i unhook the r/r the lights go out . ignition is new i think i need a new r/r and batt and reg thanks for the replys fellas

[Bashan]

If the truck hadn't been running you could have got away with jumping like that. But since it was running you probably did some significant damage. Check your fuses, they're probably toast. I go through the wires and connectors and see if any are melted. There might be some bulbs blown and you'll need to check your R/R and CDI. Good luck and keep us posted, we're here to help. Rich

well u can unplug the r/r and the lights go out . at the fuse when r/r is plugged itll spark pretty bad and when u unplug the regulater they will go out 2 .my batt is toast just dont know were to start with replacing parts.CDI is well was a new racing one .i have two of these scooters the other one i was riding one day it was raining started missing ,bogged down and shut down waited a few hrs it started back but only ran for few minutes now no spark and no power 2 the cdi . one is a DC and the other is a AC so wiring totally different............ grrrrr

When you say unhook the R/R do you mean all of the wires to it? The R/R is a rectifier and regulator so you wouldn't need to order a reg too. One nice thing about Chinese scoots is the parts are cheap. If I were you I'd order a CDI, R/R, coil, and spark plug. If you end up not needing them you have spares. If your battery is old you should probably get another one. At the very least I'd take it to a Auto Weinie and have them load test it, make sure it's a load test. Here is the multimeter test for your ignition switch.

I'm not sure what you're referring to here. Rich

[roketafan]

rich i have two scooters is what i was saying one is ac the other dc and jimbo that makes sense too

[Bashan]

Good point Jimbo, I'll have to remember that. As for the AC and DC systems, they're very similar. The DC just means that the CDI power comes right from the battery and not a red/black wire from the stator. Also, you won't see a killwire in the DC CDI because the switch shuts off the power to the CDI and you don't need to ground the coil out to stop the engine. Other than that most of the lights run off of a yellow AC wire just like an AC fired CDI system. Rich

[sprocket]

jimbo

Where does the power come from that feeds the CDI for the spark?

[sprocket]

Thanks jimbo...I have never seen a DC CDI with a kill switch wire.. live and learn

[sprocket]

Probably means they can use a single wiring harness, across a number of different brands...but I'm an AC CDI guy...

[roketafan]

well imma bye a stator ,new kill switch ,batt,and croos me fingers o and a stator puller from srappydog i hope they have 3 wire kill switch ?

[roketafan]

dang my typing sucs lol

heres a pic of my scoot
