Anyone good at electrical workings? I've never had problems, but do now, and not really sure where to start. Here's my story, if you have some guidance, it would be very appreciated! Okay, had issues with this machine at the Rampage. It wasn't reving without spitting and sputtering our last day. I thought maybe it was a carb issue. Today, we put a 400EX carb on it. We tried to test before putting everything back together. We got a brief fire, then just kick, kick, kick. I noticed the voltage regulator wasn't hooked up. Plugged it back in, still no fire, sprayed either in the carb, no help. Pulled the plug, couldn't see a spark. Tried checking ohms on the regulator, it wasn't reading, then read good, wouldn't read again. Not sure if my meter wasn't getting low on battery. Plugged it back together, got some spark. Put the plug back in, got a brief fire again, then nothing. Pulled plug again, couldn't get a spark. Does the voltage regulator have anything to do with spark, or is it just to maintain the lights? I'll look through the manual and see if there's a way to check the electrical out of the stator. Never had electrical problems before, and not really sure where to start............................new battery for my meter will be first place!

OK, I will put this up as easy as possible....(hopefully) A) Stator GENERATES electricity(AC voltage usually 125 VAC) by spinning conductors past a magnet B) The electricity is then sent to the Regulator/Rectifier where the voltage is transformed to 12-14 volts DC(VDC) C) The CDI is distributed some of the VAC which sends it to the coil/condenser/ignitor where the electricity is stored for the use in IGNITION spark
When Ohming your stator your OHMIC value between the 3 wires should be consistent. Without knowing the stators winding, I can't tell you what the TOTAL value of all 3 should be. Also Ohm the stator to a GOOD ground. If any of the 3 wires(or what ever you have) shows ANYTHING to ground, the stator is shot.
To check the electrical out of the stator get your probe into a single bare wire, and the other probe to ground. Most stators don't produce voltage till they get up over 2-3000 RPM. How strong is your battery. I have seen a bad battery kill the spark. Pretty sure I just had it happen to me yesterday.
Can you pull start it?

I'm being told the regulator should have nothing to do with the machine actually running. It's there to control the power going to the lights? This trike doesn't have a battery. I'm going to start with the switch on the handlebars, and see if that's losing contact. From there, I'll have to finger out how to check the stator. I do have another CDI I can test with, but need to look into checking the ones I have. Thanks for the helpful information barncat!
Of all the machines that I have (dozen, or so), this is the first time I've run into a problem like this! I feel like a fish out of water.......

Correct, the regulator is there to protect and feed ANYTHING that runs on 12vdc.
The switch would be a good place to start, it sounds like the culprit. Stators are pretty easy to troubleshoot. If you find the wires that come from the engine side of the stator, look for their junction, that is where you want to test.

most stators have a charge side and a run side one is for lights battery ect. the other is for running the motor. On my boys bike his would not charge the battery but the run side was good so we could pull it to start it.. then the new stator would charge the battery but after some time it would open on the run side and kill the quad and you could not start it until it cooled back down. replaced it again and it is fine.. Like was said if any of the wires coming out of the case to the wiring harness are grounded you have a short in the stator.. just my experience.. hope it helps...
