Electrical output of a 65cc chainsaw?

[brt3638]

I start early in the morning before the sun comes up, and my saws don't stop running till after the sun goes down. I want a couple little stand alone led lights. On my kick only shovelhead, I had a magneto/capacitor system that didn't need a battery. Would a setup like that work on a saw? Would I need the handle bar heater flywheel? Or could I run the lights from the coil?

I've never seen a shovel head Harley that only had a kicker on it unless it was some custom affair .That said even with a mag it should have had a generator and a battery .The old pan heads had a 3 brush generator that only had a relay ,not a voltage regulator .The only put out about 10-15 or so amps at 6 volts .Lights weren't all that great either .

Might have to scour Ebay for one of them old Mccullochs 10-10 generators. Or grab one of them little HF 2 stroke generators.

Both mine had magnetos and generators. But were kick only, rigid, open primary, death traps.

I’m not sure of actual powers output. And as cool as a chainsaw with headlight be, your better off with a high quality head lamp.

Wonder what kind of voltage the Arctic’s are puttin out?

I doubt you could run LED lights from a coil, because a coil by it's nature is a switching power supply. LEDs require a steady input for it's semi-conductor to switch the LED on and off many times per second.

I would look at getting a matching recoil starter assembly from a Husqvarna 372XPG, Stihl whatever, etc. and use the output from that to drive the LEDs. Whatever the output is for the heated handle bars, I am sure you can find a matching LED in the same voltage range. You might need a capacitor of sorts to level out the voltage. I would tend to go with an automotive LED because they are usually pot well to resist vibration.

I would build a separate coil driven by the flywheel's magnet, and make a rectifier with a smoothing capacitor, maybe even use a super-capacitor. Then I'd use a switching boost or buck converter if needed, and another capacitor or supercapacitor for energy storage. It would be cool having lights on a chainsaw. I think if you knew what you were doing you could get a lot of light from just the flywheel magnet.

Or you could just get a headlamp lol. Some interesting info in here from guys with a lot more knowledge than me, but the phrasethat comes to mind is “just because you can, doesnt mean you should”. Id rather not run a chainsaw in the dark anyway

A headlights on a saw is not only kinda ridiculous, its would be highly useless too. The saw is by function cutting through wood so any attached light would get blocked and not be helpful. A better idea as mentioned is to have the light above the work area i.e on your head where it lights up whatever your looking at. But fitting Harley parts to a saw does sound cool, its just a bad idea. Like a miner fitting a light to his pick or shovel, its dumb.

The LEDs on my $20 HF 18v drills are a fine addition and come in handy, so, lights on tools have their uses. I can see where it might be handy on a chainsaw. BUT, I consider operating a chainsaw in the dark extremely dangerous because the hazards you step on and spring poles. Though for firewood bucking, maybe less so.

That being said, I have used LED Energizer headlamps (ones with a single strap) on my chainsaw helmet to finish up a job in the dark. It is something I avoid, but, the question was about how to get her' done.
