How many amps if any does the stator put out?.gy6 engines

Glennby,
Good question! Hope someone here can give an answer. It will vary because not all stators have the same number of coils. The more coils, the higher the output. Scoots of 50 cc and 150 cc generally have smaller stators and output fewer amps. Some of the 250 cc scoots had smaller stators originally but those were bumped up when it was found more output was needed. My 250 CFMoto engined scoot has the 18 coil stator.

Hi: Scooterollie is correct, it all depends upon the number of coils (poles, windings). From what I've been able to dig up, it would appear that the "stock" gy6 arrangement for 150cc is 6 coils, with 5 used for system charging and one for the cdi. This link provides a pretty basic explanation: www.buggydepot.com/buggy-tech-center/150cc/Yerf-Dog-Blade-GY6-Buggies-Parts/1Here are the capacity specs for a few models: Stella: 12 volts/96 watts Argo AR150-18: 12 volts/98 watts Vespa 5-port: 12 volts/96 watts So, it would appear that the average capacity is about 8 amps (~96W/12V) Regards, BA |

then that kinda goes with the battery amps as well then right?.mine sez 7ah.

Not necessarily. Seems most 150 scoots are equipped with the 7 amp hour battery. I replaced the one in my 150 with a 9 amp hour AGM style that had exactly the same dimensions. Cold start cranking power was stronger. Not a problem for the stator to handle for recharge.

Glennby: "Amp-Hours" is just a way of rating a battery's sustained load handling capacity. For example 7AH means that, at the battery's nominal voltage, it can service a 1 amp draw for 7 hours, a 2 amp draw for 3.5 hours, a 7 amp draw for 1 hour, etc, etc. (all values approximate). Similarly, when properly severed with an uninsulated pair of wire cutters, a household power cord can supply enough current to make your entire life flash before your eyes in the approximately 100 milliseconds it takes for you to land on the opposite side of the garage.

In a backtracking method, based on my Fiji 150 GY6 engine powered scooter.
Two 18w headlight bulbs draw 3 amperes. A 25 watt tailight bulb draws 2 amperes (with brake light on, less without brake light on). Running lights and instrument cluster could draw about 2 amperes maybe 3 amps total.
Yields a need to supply 8 amperes to power those items. So the alternator needs to provide at least 8 amperes up to about 10 amperes.
The DC circuit fuse is a a ten ampere fuse which might be a good hint too.

Been there, did that when I was a kid! |

don"t forget that the headlights, taillight and dash run of the lighting coil on the stator, this is a separate circuit from the charging circuit.....
