Voltage of the magneto?

But same wattage, it's not the volts I'm worried about, it's the total power I can derive from the system. Are you sure that 1k olm resistor, with the way you hooked up that tester, didn't alter your calculations or something? Those values are scarey close to being 1k ohms.. In fact it's just 29ohms off..

You're saying normal voltage is about 30-35, if I cut my wire and make my meter part of the circuit I could get the current right?

V=IxR (voltage equals current in amps times resistance)
W=VxI (watts equals voltage times current in amps)

V/I=R
34v/34mA=1K exactly, not 290 ohms off

I said 29 not 290 ohms, time to shop for reading glasses jaguar ;)

Did you make your meter part of the circuit, or cross it over the circuit making it parallel to the mag?
 
sorry, my eyesight isn't too good. But the answer is still 1K.
yes parallel to the coil and the resistor. all three are in parallel
 
Lol no wonder... Amps must be measured in-line, like you would have to cut the blue connection to the cdi, and place the meter ends between the too, it would appear you measured the wattage being used by the resistor (it probably took the resistors reading simply because it was the shortest path, and your current being passed across the 2 wires wouldn't want to do more work than what it was already doing, electricity is a b**ch,) but that's OK, because I think we are getting onto something. I'm busy with work tomorrow at 8am, and will be working for 8 hours till 4:30, so can't go out and start a motor with a meter in series to my cdi, what kind of meter do you use? Like digital r analog?

If you could tinker around for me it would be much appreciated, it could also open a lot of doors for other people too, as far as getting power for lighting, which is very important at night.
 
the resistance that the CDI presents is different for the positive half of the wave than it is for the negative half of the wave.
So that complicates things. Pure wattage reading of a coil is done the way I did it.
 
Maximum wattage for these motors would be about 1400w which is the 2hp or so that they produce.
Big enough magnets and lots of coils and you can drag all the hp out of the motor electrically.
Glue super magnets to the clutch rim and coils to the cover and you have a pretty efficient generator.
I'd go for 3 phase windings (6 coils) and 6 diodes to rectify it, with a simple voltage capping regulator off a dirtbike or sled.
You could use 6 permanent magnets glued into an aluminum ring bolted on the clutch.
I oughta take out a patent.

Wait a minute, clutch is going 1/10th speed of crank.
Put it on the crank, either end. If not enough room, go 4 diodes, magnets and coils.
Single phase. Cheaper, lighter.

Are you being serious about putting it directly on the crank? Doesn't seem like a fantastic idea at those speeds... But that clutch plate idea had a thought going (watch out!) some careful machining of a dead crank, modifying the crankcase and cover, a second bevel gear could be mounted up along the clutch gear, which would spin the new small gear at the same rate as the crankshaft, and would continue spinning after the clutch was disengaged too... Hmmm...
 
Yeah I'm serious. It would take less copper and steel if driven directly off the crank.
I'm looking at using the motor to charge batteries on a hybrid. The rotor and mag are pretty much maxed as is but there is a lot of room in there. A redesign of the pickup coil could provide spark and volts.
