I think I found the problem my battery charged to 12v and with the tester it drops down slowly ( self draining) all the way to 0 while sitting on the work bench going to get a new one in the morning and Il keep you guys posted lol

 

Looking around for some advice as i don't have any spec on my charging system i just found you guys talking same stuff as im in right now !

Sorry to cut right in like that but theres not much people talking on the subject that i have found so far !

Anyway ! Mine is a 110cc GIO mini hummer with the 2 coil 5 wires stator ... i actually tried 3 rectifier and no better voltage ....and i mean if the battery hold a charge of 12 volts it will charge slowly goin up at best 12.5 to 12.75 with time but if i put the battery on the charger for some time let say so the battery is up to 13 volts then it will charge let say to 13.5 volts and a bit more if i give it time to climb to ...

brake light or head light ON will discharge the battery as charging system is not providing enuff amps ...

So my question are ... Is this normal on those cheap bike ?? Should i expect more amps from theses charging system ??? If not working propely as im thinking so could you also tell me what wire to check or test to make on this stator and mostly
what AC voltage should it give me the rectifier unplug ? Guest its also 25 Volts when not control by the rectifier ???

Thanks !

 

This sounds like progress.

After you get that new battery installed be sure to test the charging system to see if it is working. If the charging system is not working, and you aren't religious about using the external charger to keep the battery topped off, you will quickly have a third bad battery.

 

I've heard others complain that their 110cc engine charging systems are wimpy. Others say they have no problem. Here's a very direct and unambiguous way to see if the battery is charging or not (and by how much):

Set your meter to read current on the 10 amp scale (you will have to move the red lead into the 10 amp current jack as well as set the rotary switch to the right amp scale). Remove the main fuse, and insert your meter across the fuse holder terminals. Start up the quad and read the charge/discharge current directly and instantly in amps. Note that the polarity of the meter reading changes when the battery current switches from charging to discharging (or vice versa).

I have a 150cc quad with an 8 pole 55 watt stator. This is what I measure on mine:

Engine Idling, no headlights: Battery is discharging at 0.3 amps
Engine Idling, with headlights on: Battery is discharging at 3.0 amps
Engine at about 3500 RPM, no lights: Battery is charging at 3.5 amps
Engine at about 3500 RPM, with headlights on: Battery is charging at 0.2 amps.

I have two headlights, and the tests were done on high beam. The point is that my charging system can't keep up at idle, and barely keeps up at speed with the lights on. At high speed with the lights off, the battery voltage is 14.5 volts.

Since I don't have a 110cc quad, I don't know what to expect on a 110cc engine as far as charging/discharging current levels with the lights on/off at high/low engine speed.

Hmm, maybe you could measure this and post this info. You would be a pioneer, expanding the knowledge frontier, and setting the comparison benchmark for all other 110cc machines in the world.

The output of battery charge winding on my quad (regulator disconnected) is 9.5 VAC. At idle is is a lot more since the engine goes from 600 RPM cranking to roughly 1900 RPM idling. So 25 volts ac at idle is in the ballpark (Output voltage is proportional to engine speed).

I'm also becoming deeply suspicious of the compatibility of various 4 pin regulators with each other. Where did you get your regulator(s)? From Gio? eBay? I've bought and disassembled two off ebay. They are completely different designs, but use the exact same connector. They are *not* interchangable. This is still work in progress. I don't have all the answers yet.

 

ok I could be wrong(I normally am just ask my wife).I have always been under the impression that if it has a battery the charging system helps run the juice to the motor and whats left over charges the batt. take the batt. out and try to jumpstart it. if it dies when you unhook the jumper cables , the charging system is bad. if it keeps running its the batt. by the way these small batts. for these quads suck ***. try and get a gel cell and you might have better results.Seth 03

 

This is true for a few newer quads but not most. The reason is that the ignition system usually runs off its own high voltage power supply (100 to 300 volts AC) coming off of a separate winding in the stator. The battery and battery charging system have nothing to do with keeping the engine running. Its sole purpose is to turn the starter motor and run the lights.

Think of your lawn mower. It doesn't have a battery, starter, or a charging system, yet it starts up and runs when the motor is turned via a pull rope. Small engines all started off this way - starters and batteries were added later. But the original ignition design stayed the same.

But now some newer quads use a CDI that runs off 12 volts instead of the stator high voltage supply. Inside these CDI's is a voltage converter that takes 12 volts DC and steps it up to several hundred volts to run the rest of the CDI. For these quads what you say is true.

Also, many get confused between the high voltage running the CDI (a few hundred volts) and the actual ignition high voltage feeding the spark plug (10,000 volts or more). The CDI output still needs to be stepped up a bunch more to fire the spark plug. So you still need an ignition coil.

 

I agree. I still stand by what I say. I would bet a doller to a dog turd that geo 110 has a cdi and that the batt. is nessacarry to run the motor. older engines had a magneto that provided for the engine, newer engines have a stator and rectifier and cdi that provides power for the engine and charges the batt.Seth 03

 

Well, I've been wrong before - but in this case I don't think so. I have to disclose that I've not seen a Gio 110cc. I don't even think they are legal here in California. But there is a lot of info out there on these machines.

For example, 065KFR posted a Gio 110cc wiring diagram copied out of the Gio manual just the other day in the Kid's Quad section. The link is here:

http://forums.atvconnection.com/kids...g-diagram.html

This wiring diagram clearly shows that the CDI is powered straight off its own stator winding (and must therefore be AC powered), completely separate from the battery charge winding.

Also note that the CDI pictured in the wiring diagram is a five wire CDI. I've not seen nor heard of a five wire DC powered CDI. If the CDI in question turns out to be four pin then it would probably be DC powered.

Note that in Wabo's post he described a two coil five wire stator. Looking through parts vendors using that description and 110cc engine in the search field I only get pictures of standard run of the mill stators with a battery charge winding (heavy gauge wire and hundreds of turns) and a high voltage winding (thousands of turns of very fine gauge wire). There actually is a third winding (the igntion trigger pickup) on these stators, but it is small and mounts outside the flywheel so I guess it doesn't count for some reason.

I have a 2 year old chinese 150cc quad with an AC powered ignition. I know for a fact that it runs just fine with the battery and rectifier/regulator removed from the quad.

 

My Yamoto 150 runs fine with no battery in it...My Jetmoto 125 and mini utility both have dead batteries...and after being jumped started run just fine..

 

Here's a picture of the 2 coils Stator i got on this bike ...I also got that bike on eBay

Well Seller seems willing to send me another stator for free so im gonna wait for it for now ...

This week i will give the charging system a few test as soon my son is not around (...the quad is for his birthday present and its been hidden from him so far ...)

If my memory good i also check on that wiring chart cause i got it printed out on a book but the wire colors might be mix up or maybe for an older model ...anyway i will check that back !
