That's exactly what I was thinking in post #8. Like my outboard motor, an extra coil near the flywheel, using the same magnets as the magneto, to generate battery charging power.Your generator is probably two magnets (one N and one S) embedded in the flywheel and a pickup coil, giving you a positive and a negative pulse each revolution. At 3500 RPM, this would give you a frequency of ~58 Hz. The capacitor banks needed to smooth this 2.5 amp output whould be huge, so I would just skip the caps. You probably will only notice the flicker at low RPMs anyway.
Especially since you edited your content behind us. If you want to add additional details, please do it by replying to the thread chronologically, NOT by editing your previous posts.1) Apparently some of you haven't read what I wrote last!
The Bridge used is rated for 8A and 200V, 800V
What is a "half-circle DC output"?The alternator is a half-circle DC output. Don't know much more about that.
That's if it really is AC... +/- Xv, or is it really just the positive pulse wave without the negative portion based on the design of the alternator??It's what you would expect from rectifying 15VAC combined with voltage drop across two diodes in the bridge. There's nothing unexpected.
The light has always been dull, it's a 37.5W Yellow Incandescent. I wanted brighter and whiter.Being you said the bulb was very dim,....I would check the flywheel and pickup assembly. Check the clearance to spec and make sure its free of crud. Look for an adjustment. If you don’t want to disassemble....see if you can get the long spout of contact solvent cleaner on target while engine running. Douche it out good.
I still recommend the replacement bulb I suggested($8), before any mods.....just to see if it is close to the brightness you expect.
It will help determine if you output is really what you think it is.
That would give the same voltage after the rectifier+cap, under low load. Either way, the rectifier+cap acts as a peak detector unless there is a load to draw the voltage down a lot during the "off" times.That's if it really is AC... +/- Xv, or is it really just the positive pulse wave without the negative portion based on the design of the alternator??
Beginning to think that this is what I am passing through my bridge rectifier..
