Voltage ???

[McDerry]

well, got the trike running :w00t: Took it for a spin with the ubber redneck bike brake throttle that only opens it 1/4 way max.... It still halls. Spent the afternoon powersliding it around the yard. Get the throttle rigged up to go wide open and Ill be realy enjoying this.

Well figured, Id get some lights on the 200s so I can run it at night, wasn't sure on the voltage, so, hey ill jsut slap the voltage meter on it. grounded the negative lead, and slapped the postitve lead on the yellow wire coming off the stator.

:confused: the voltage went negative, very confusing, so I assumed the ground on the bikes is positive and swapped the leads around. Even stranger the voltage still showed negative.:confused:

Am I missing something, or is this a obvious sign of the coil in the stator for the lights being bad.

its 12 volts i too have a 200s

It is 12 volts AC. The trikes without batteries ran the headlight on AC not DC. Try your meter set to AC.

Yep AC.

12 Volts not anymore

20v AC, time for some a couple capaciters and inverters.

Oh yah, I held the leads to the bare flapping wires with my hands, and electricuted the *Edited**Edited**Edited**Edited* out of myself.

AC hurts.

DC burns !!!! :lol:

Alternating current gives you that buzzzing feeling..... from - to +.. Hertz..


DC just burns like hell.... takes a bit before you realize it does... but god i hate shocking myself..

A voltage regulator would do the job. Keeping things at 12v.

The 200s did not use a voltage regulator. The lighing coil was wimpy enough, just connecting the headlight to it kept the voltage down. Hook up a light and measure the AC voltage, you will find it is down around 12 volts (when the motor is reved up)

Voltage is voltage,

if the winding is putting out 20v at idle, it will put out 20v at idle, no matter how much load I put on it. The voltage drop after going through something may be different, but the initial voltage will still be 20v. Id need 800 so feet of wire to drop th voltage down to 12v just from wire resistance.

I can regulate the voltage to where I need it no problem, the watts to run the fixtures will still be there.

It is the IR drop in the windings themselves. Hook up a car headlight and see. That stator cannot drive it.

of course not

the stator doesnt put out the wattage to run a car headlight

not because of the voltage

a car headlight is a 12v headlight, if it had the wattage it would light it all day long.

On another ntoe I can slap a 12v headlight on the 20v all day long, it will still draw the same watts, but at a lower amprage, almost half.

[ATCnut]

Do you understand Ohm's law

V = IR

V is Voltage
I is Current
R is Amps

P = VI

P is power

If the stator could always put out 20 Volts, you would be able to draw infinate current out of it. It would be what is called an ideal voltage source.

There is Theven's Therom.

That any real voltage source can be modeled by an ideal voltage source with a resistor in series. That means that the more current you draw, the lower the voltage will be.

If you do not believe me, check the wiring diagram from Honda. A 200s did not have a voltag regulator. The lighting coil is directly connectied to the headlight.

[McDerry]

Your forgetting something there. Theres no resistor prior to the light, so the light will recieve all 20v, function as aresistor, and drop the voltage. The stator will always be putting out 20v.


Oh you have the variables wrong in ohms law

V = Voltage
R = Resistance
I = Amps

[ATCnut]

You are correct, I mistyped Ohms law.
