Iseki finally got that well deserved wash. Also a new alternator belt, so no more screeching.
Love the engine access here. Top hinges up, side panels just lift out to get access to everything. Nobody appreciates good engine access like a former sailboat owner!
Drying off now, then time for some fresh grease.

New #Documentation: Saab 93: Alternator Replacement (1.9 TTiD)

My #alternator is only ~2 years old; is its voltage regulator already failing? 14.7v does indeed seem high...
A magneto is an #electricalGenerator that uses #permanentMagnets to produce periodic pulses of #alternatingCurrent. Unlike a #dynamo, a magneto does not contain a #commutator to produce #directCurrent. It is categorized as a form of #alternator, although it is usually considered distinct from most other alternators, which use #fieldCoils rather than permanent magnets. Hand-cranked magneto generators were used to provide ringing current in #telephone systems.
In 1904, Ernst Alexanderson designed the first high-power alternator useful for generating radio wave frequencies. #Poetry #Science #History #Electromagnetism #Alternator #Alexanderson (https://sharpgiving.com/thebookofscience/items/p1904f.html)
Here is proof! On my 60th Birthday trip, she went from 99K to 100 and has many more miles to roll. Blaze has been so happy since we found (at around 60K) the source of the battery drain. Just normal wear & maintenance; most recently replacing front suspension.

PSA. If you get a new #battery from #AAA or your #car mechanic, make sure that they also clean the shmutz (I believe that's the vox technica) from the terminals that run from the #battery to the #alternator. Suffice it to say, I learned this the hard way.

Dude wants to pull "300 ish Amps at idle" from an aftermarket 325A 12v #alternator. I predict this will end with heartache and poorly-founded accusations.
I'm guessing <100A continuous/hot at idle and <200A continuous/hot at cruising speed *after* he upgrades the Big Three and runs a separate NEG return.
I swear 90% of "influencer" content about #alternator charging #LiFePO4 on #youTube is fearmongering and ignorance.

Motorcycle Regulator By Popular Demand
A few weeks ago we posted a build of an avid motorcycle enthusiast named [fvfilippetti] who created a voltage regulator essentially from the ground up. While this was a popular build, the regulator only works for a small subset of motorcycles. This had a large number of readers clamoring for a more common three-phase regulator as well. Normally we wouldn't expect someone to drop everything they're doing and start working on a brand new project based on the comments here, but that's exactly what he's done.
It's important to note that the solutions he has developed are currently only in the simulation phase, but they show promise in SPICE models. There are actually two schematics available for those who would like to continue his open-source project. Compared to shunt-type regulators, these have some advantages. Besides being open-source, they do not load the engine when the battery is fully charged, which improves efficiency. The only downside is that they have have added complexity as they can't open this circuit except under specific situations, which requires a specific type of switch.
All in all, this is an excellent step on the way to a true prototype and eventual replacement of the often lackluster regulators found on motorcycles from Aprilia to Zero. We hope to see it further developed for all of the motorcycle riders out there who have been sidelined by this seemingly simple part. And if you missed it the first time around, here is the working regulator for his Bajaj NS200.

Motorcycle Voltage Regulator Uses MOSFETs
For how common motorcycles are, the designs and parts used in them tend to vary much more wildly than in cars and trucks. Sometimes this is to the rider's advantage, like Honda experimenting with airbags or automatic transmissions. Sometimes it's a little more questionable, like certain American brands holding on to pushrod engine designs from the '40s. And sometimes it's just annoying, like the use of cheap voltage regulators that fail often and perform poorly. [fvfilippetti] was tired of dealing with this on his motorcycle, so he built a custom voltage regulator using MOSFETs instead.
Unlike a modern car alternator, which can generate usable voltage even at idle, smaller or older motorcycle alternators often can't. Instead they rely on a simpler but less reliable regulator that is typically no more than a series of diodes, but which can only deliver energy to the electrical system while the motor is running at higher speeds. Hoping to improve on this design, [fvfilippetti] designed a switched regulator from scratch out of MOSFETs with some interesting design considerations. It is capable of taking an input voltage between 20V and 250V, and improves the ability of the motorcycle to use modern, higher-power lights and to charge devices like phones as well.
In the video below, an LED was added in the circuit to give a visual indication that the regulator is operating properly. It's certainly a welcome build for anyone who has ever dealt with rectifier- or diode-style regulators on older bikes before. Vehicle alternators are interesting beasts in their own right, too, and they can be used for much more than running your motorcycle's electrical system.

Modified Car Alternator Powers Speedy DIY e-Bike
Your garden variety automotive alternator is ripe for repurposing as is, but with a little modification, it can actually be used as a surprisingly powerful brushless motor. Looking to demonstrate the capabilities of one of these rebuilt alternators, [DIY King] bolted one to the back of a old bicycle and got some impressive, and frankly a bit terrifying, results.
We should say up front that the required modifications to the alternator are quite extensive, so before you get too excited about building your own budget e-bike, you should check out the previous guide [DIY King] put together. The short version is that you'll need to machine a new rotor and fill it with the neodymium magnets salvaged from hoverboard motors.
A custom built alternator rotor is the key to the project.
Once you've got your modified alternator, the rest is relatively easy. The trickiest part of this build looks like it was cutting off the bike's rear wheel mount and replacing it with a plate that holds the alternator and a pair of reduction gears pulled from a 125cc motorbike. Beyond that, it's largely electronics.
Naturally, you'll also need a pretty beefy speed controller. In this case [DIY King] is using a 200 amp water-cooled model intended for large RC boats, though interestingly enough, it doesn't seem he's actually running any water through the thing. He's also put together a custom 1,500 watt-hour battery pack that lives in a MDF box mounted under the seat.
To test out his handiwork, [DIY King] took to the streets and was able to get the bike up to 70 km/h (43 MPH) before his courage ran out. He thinks the motor should be able to push it up to 85 km/h, but he says the bike started wobbling around too much for him to really open it up. In terms of range, he calculated that while cruising around at a more palatable 30 km/h (18 MPH), he should be able to get 100 kilometers (62 miles) off of a single charge.
If you like repurposed motors and suicidal bike speeds, you'll love this build that uses a washing machine motor to push a rider to a claimed 110 km/h. If you're not worried about speed or range, then this supercapacitor e-bike is certainly worth a look as well.
[Thanks to Mike for the tip.]
