hi i just bought a roketa 250cc 2wd atv from a guy, only paid 150 and its like brand new but theres a problem, when i plug the voltage regulator the fuse pops? i also have 2 wires by the battery that arnt connected and not sure what they are for, ill post pics soon, and thank you for any help

 

trace the wires at the battery so you can identify which one is the positive/negative. what are the color codes of the suspect wires? make sure you're not missing any inline fuses-especially if they have the normal connections on the ends of the suspect wires. typical male/female connectors of certain styles...etc.... let us know

 

ok heres some pics the only fuse i see is the one where battery is but in the pic you can see theres 2 wires, black and green. i have no clue what they are for but they have some kinda connectors. i was thinking to first replace the regualtor, rectifier?

 

without a wiring diagram to refer to for specifics, those connectors on the green/blackwhite look like they hold a 30amp buss fuse like my kawasaki!

Mr. Firemouth!!!!
Hhhheeeelllllpppp

 

so thats for a fuse also?

 

i'm unsure but it sure looks like it. let's get Mr. Firemouth and LynnEdwards and mywifesquad's opinions on this. they're the experts. meanwhile, here's a wiring diagram. let's study this and see what we can come up with while we're waiting on them..

well, looks like a fuse on the lower right on what's labeled as a RELAY COMP START that shows B/W to Y/G connectors. what do you think? i wouldn't try to install a fuse until one of these electrical experts looks this over. i don't want you to make a mistake and burn it up.

 

The terminals in the wiring pic indicate they are for a fuse. However that does not mean that those wires are intended for any use on this bike.
They both seem like ground wires according to the diagram.
Lynn will know more.

Do NOT connect them. First test them with a volt meter. Make sure they do not have power. Check Key on.

I would check from the battery forward each wire and locate the source of the short. Use a voltmeter. If you suspect it to be the regulator you can replace it and see if all is well. If the same problem occurs, I would continue to remove the wiring wraps and check each and every wire. Your main fuse should not be blowing.

For this problem, I would want to have a voltmeter and try to locate the problem. I would also follow back the available disconnected wires and see if anything is unplugged or I would trace those wires to their sources and proceed from there.

Let us know if a new volt regulator helps.

 

I was looking at the same wiring diagram for a Roketa 250cc as Jaster94 (it could be that I got that from him a while back). I'm not sure how much it applies to your quad - the number of pins on the regulator is wrong for example.

Let's start with the regulator: Regulators aren't supossed to ever draw current from the battery. They are supposed to *supply* current to the battery when the stator is putting out sufficient voltage and current to do so. When the stator isn't supplying enough voltage/current the regulator just stays off - it neither draws current from or supplies current to the battery. So if the regulator pops the fuse when connected then it is miswired, is the wrong regulator, or is bad.

Any sign of hacked wires in or around the regulator? I'm trying to get a feel if someone else worked on this problem before, did some creative rewiring, and gave up.

Does the fuse poping stop if you disconnect the stator at the connector where the stator wires come out of the engine?

The two extra wires: Look for wires that tie to engine ground via a lug under a screw. What color are those wires? Green? Does your green mystery wire tie to engine ground?

Look at your CDI kill switch pin as shown below:



Do you have a wire on that pin? Is it black/white? If the answer to the above questions is yes then I think your mystery wires are just kill switch wires. Maybe a lanyard pull rope kill switch? The reason I suspect this is that these two colors are commonly used for ground (green) and kill (black/white). It certainly doesn't match the wiring diagram I have (which is the same as the one Jaster94 posted), but the regulator doesn't match either.
