I finally got around to installing the Moto Tassinari VForce3 reeds in place of the Stage6 VForce3 reeds yesterday, as detailed farther in THIS THREAD. I went to start it up, and it just wouldn't fire. It's sat with a tank full of fuel for a few months I guess, so that was my first suspicion. I opened the gas cap and it didn't have that typical nasty bad gas smell. I still drained it out and took the bowl off of the carb for a look. Looked clean. Sprayed it out quickly anyway. I just went and got a couple of gallons of fresh fuel this morning. Filled the tank and it started on the second kick. I had almost forgotten how nasty that Peace Pipe sounds. :devil: I'll ride it sometime soon to see if I can tell any difference before I start doing a little more to it. ;D Woulda rode today but it's 40 degrees and getting ready to rain and snow. The RADAR says it should be raining on me now, so it can wait. |

I have a question for the electrical gurus out there. I've got an NCY "alternator" kit sitting on the shelf, waiting to be installed at a later date. Since it's something I've seen asked more than once, I wouldn't mind trying to compare it's output to my stock charging/lighting system. The obvious way to start is simply to see how it works. Assuming it works fine with my 60W headlight and the rest of the electrical system, I wouldn't really know the difference other than maybe looking at the brightness of the light at idle and clues like that. Anyone have an idea of a good way to compare the output of the two more scientifically than if the lights work? It can't involve any expensive test meters etc... I've got a multimeter and I've got a resistor I've used to measure draw before for the stereo on the Venus as shown below... I used a 1 ohm, 10W, resistor inline between the amplifier and battery terminal and measured the voltage drop across the resistor to determine current. For reference, the volume goes from 0-30 on this unit. Here's what I came up with.  Volume @ 15, White Noise : 0.17A Volume @ 15, Radio : 0.29A Volume @ 30, White Noise : 0.57A Volume @ 30, Radio : 1.36A I'm guessing that it would probably peak between 1.5-2.0A with a good signal from an MP3 player. I'm guessing it wouldn't really tell me anything unless the system was maxed out trying to do something like that. I dunno, I know enough electrical to get by with run of the mill stuff, but beyond that I could use some (a lot of) help. |

Could you run it at a set RPM with the resistor on the battery and measure the voltage drop with the two different charging systems? It wouldn't tell you that x system produces x amount of watts, but knowing how much power relatively they produce would be handy.

Here are my thoughts.
This will involve having some way to measure temperature... either by contact or by infrared. Your cht ring spark plug t/c could work but I'm thinking a mechanical guy like you might have a remote infrared thermometer.
Cheap automotive defrost heaters can often be purchased for around $10 but an a/c house current model may work as well... the temps measured will just be much lower. You could be limited to using the household one if the temps achieved by the 12v. exceed your thermometer's measuring limits.
Simply see which stator achieves the highest temperature whilst holding the revs the same for each test. I suggest using a 10A or larger fuse. A household resistance heater I just ohmed out checked at around 10 ohms. Measure the temperature at the same point on the coil or band for each test and let the fan blow over the elements, at least for the automotive heater. Some disassembly of the heaters will likely be necessary. Probably holding the revs at 3-4000 rpm should be good.
I've done some searching and this is the best I can come up with.

Interesting idea. I've got a non-contact thermometer that reads pretty high (forget how high now). Something about me + this makes me think keep a fire extinguisher handy though.

yeah and then the only thing you are measuirng is the dc output to the stator your not measueing any of the ac output
but by reading around your dc output may be limited by your r/r

I just happened to think of this as a pretty much ready heavy load that would provide good loading. The household heater elements probably won't show a lot of heat but you're just looking for a difference. It seems to make sense but my hairbrain ideas haven't worked out before too. Lol. I started to hook a household heater up to my truck battery but I've had the mother of all colds and still don't really feel like it.... maybe tomorrow since it is a public holiday and I don't go in to work.

I was trying to think of something along the lines of your idea Reg, but that I had around. Drawing a blank. I thought of an amplifier at first and see how loud it gets with a dB meter... but I only have the little one from the Venus that draws 2A maybe max and then a 1000W hooked to a 15" Kicker L5 that probably wouldn't even turn on. I'll be stuck without electricity for 2 days this week while some work is being done in the house and it's supposed to be mid 50s those days so I was thinking I might be able to screw with it then. That's why I was trying to think of what I had around. Not sure what those heating elements cost local, I might be able to check tomorrow. I've got a little heater for the house, but I'd rather not cut it up to wire it in and to be able to read heat since it's newer so it's got the plastic screens and such that don't get hot in case it tips over.
One basic question is, even if you have some pricey meter, can you actually measure a stator's potential without it being loaded? Or maybe the expensive meters simulate a load? Like I said, I don't understand electricity enough to really know this sort of thing.

Well, I did a little searching and I see that even with clamp on meters you need to load the system. Of course everything I see is about automotive alternators, so they say to turn on every accessory and measure. Even if I picked up something like THIS I'd have to have something for a load. All my LED turn signals and brake lights aren't gonna make that much load on the charging side. Would a dead battery create more of a load? I've got a big car batt that's dead. Sorry if these are stupid questions. Just wanted to take advantage of an opportunity for more info for us. It really doesn't matter to me otherwise, if my lights work I'm good to go. |

All you need is line-of-sight for your IR thermometer so little or no disassembly may be necessary with a house heater. Unless the house heater has digital control (touchpad, etc.) you would need only to use jumper cables to hook the 120v. male plug up to your scooter and just turn the heater on to max.
A discharged auto battery would make a good load but you would have to assure that the state of discharge of the battery would have to be pretty near the same for both tests. This probably won't be a problem if you don't leave either charging system running for too long. The battery draws less current as it becomes charged but a large capacity battery with a small charging current builds up charge pretty slowly.

I bet some construction workers tell stories of the crazy guy trying to heat his garage with a scooter when they shut his power off after this. lol
