Is there a way to measure the wattage output of a scooter electrical system?

Yes, all you need is a Volt Meter.

Thanks, but I don't want to measure volts. I want to measure wattage.

PIE (P, for power, =IxE, or current times voltage, so if you don't have a "power" measuring devise, just measure current and voltage and multiply it. For example, if you measure 13V at 1.4 Amps, you would be measuring 18.2 Watts.)

So, Do I break the circuit at the battery to measure the amperage?

I'm pretty sure you just stick your leads on the positive and negative. I have never measured amperage though never needed to

No, To measure amps you have to break the circuit so that the currant runs through the meter. I just need to know where to break the circuit.

Measure it at the main fuse then right off the positive lead circuit is already broken there or rather it could be

Pazzo , lets be a little more clear . What is it you want to measure ? Did you want to measure the power the stator can output in AC or did you want to measure the the wattage of the charging system . Remember they are a little different .
For the 150cc GY6 I sell 11pole stators with regulator and magneto . I sell it as a set , you can have a total load of 125w DC and still charge .
Whutz answer is correct , however is it what your looking for ?

My goal is to know the max wattage headlight bulbs I can run.

what cc engine and how many coil stator is it ?

First of all what scooter do you have? Typical GY-6 stator puts out 80 to 90W. Remember the R/R controls the output of the stator and excess wattage is shunt to ground. Charging systems on the GY-6 are nominal and to answer your question about the bulbs? 35W max, want higher wattage then go to a 11-pole stator.

I have a 150cc Jonway. I don't know how many coils. I have a puller ordered to pull the flywheel and check, but it hasn't arrived as yet.

It will be 8-coil.

Is there a formula like 8 poles = x of watts 11 poles x of watts or do they vary ? I do know more poles = more wattage . I think many 150s have 8 pole and some nicer ones have 11 pole . I was happy to learn my CFMoto Echarm has a 12 pole stator since the headlight comes on with turn of the key rather than when the engine starts like most . My Echarm does not have a kickstart which has saved many with a weak battery or bad starter . I asked my dealer about it not having one and he said his truck does not have a kick start as well . I have no idea ( hope someone does ) if a CFMoto 12 pole stator , regulator and CDI ( on carb models as EFI is controlled by an ECU instead ) would work since its not exactly like the common GY6 as its LC not AC . Here is a lnk to CFMoto parts of interest www.scrappydogscooters.com/CF150_4T_1P58MJ_Parts.html If you look at the 250 they have way more poles in their stators than the smaller ones . An option may be to get a battery with a higher output of amps providing it fits in the tray as well as a trickle charger in case 55 watt bulbs take away from the stator to charge up the battery |

Measuring will only tell you what the scooter is currently putting out but not what its maximum capacity is unless you do a load test with an adjustable carbon pile and know how to use it without burning out your stator.
You will most likely need to put in a relay and a direct fused line to the battery if you go with much larger than stock. What size headlamp bulb and how many does the bike have now?

The 150's have 35W bulbs for a reason. Both bulbs = 70W and all know that the 8-pole stator engines with the other bulb load is right to the maximum threshold as far as charging and keeping the headlights going. Add any extra wattage load and you'll have a dead battery.
Something as simple as a brake light switch stuck and keeping two brake light bulbs on all the time at a extra 20W load will get the battery.
Best solution is a complete LED change out which will gain you and extra 1 volt in charging and putting in a good 12 to 14AH battery.
The 11 pole stator put out around 150 watts and give you extra wattage to play with.

Kick starters are on applicable with AC systems that don't require even a battery to kick start them. |

Well it could be an 11pole stator in there . Find the plug from the stator and tell us how many wires and the colors . Then we can get a better idea of what is in there , without opening it up .

I have one headlight bulb, I don't know the wattage. I'll look at the stator wiring.

You can also take a look at your R/R and see how many wires it has and the COLOR of the wires. Or better yet take pictures of the wires from the STATOR and the R/R and you will not have to take the flywheel off.

I have one headlight bulb, I don't know the wattage. I'll look at the stator wiring. How old is this scooter? Some of the older Jonways had 6-pole stators and with only one headlight bulb more than likely it is 6-pole. Are you sure it's 150cc because mostly 50cc scooters only have one bulb? Jonway only puts out one scooter with a stator bigger than 8 as far as 150cc scooters go and that's their 16" wheel version and it's 12 pole. Any other larger stator is on the 250cc and it's 18-pole. If it is a 6-pole then whatever size bulb you have (probably 25W) is at your limit. Might hang in there again with a complete LED bulb change out and larger battery with a 35W bulb but that will be it. If I was going to change it especially if it is a 6-pole I would go all the way to a 11-pole set up, but remember this if it is a 50cc then 11-pole stators that fit a 50cc is hard to find. |

The scooter is a 2012 model. Engine code 157qmj.

Then it most likely has an 8 pole stator.

If it is a 8-pole and most newer models are then with only one headlight bulb and a LED change out you could go to a 45W bulb with no problem.

He means replace all your incandescent bulbs i.e. brake, blinker, and markers with LED types which are brighter, nearly last forever, and require less power...

Change all your other lights on the scoot to LEDS they take less wattage so you get some left over and that will handle a little brighter headlight bulb. Get LEDS for your Taillights, Turn Signals and Instrument panel.
Take one bulb from each and get the number off of it, then you can google for LEDS they have a ton of them. The thing you just have to watch out for is the LENGTH some are longer than others and may hit the outside lens. But you can put the numbers on here and maybe pictures to see what type of bulbs you have and we can find you some.

Will they run on AC or will I have to convert to DC?
