1-wire Generator

Theses are found on Toyota's right? Has anyone mounted one on a F134?

 

Denso is an Asian part found on many different autos Toyota Nissan and Honda are just a few.

 

I live where there are 4 people per sq mile, seriously, so service options are not readilly available, making rebuilds a no go. Shipping and BS get expensive and these arent really much more than a replacement unit, but could be superior in ever way to the GenSet.

Seems a 1 vs 3 debate here. Not gonna argue theorhetical ideal vs clean/simple. That’s an apples and oranges debate.

Seems no one has one of these. I may actually put one on my A-C WD, ironically.

 

IMO old Jeeps are tractors that can go 55 MPH.

To each their own though.

 

I bought a One Wire off E-Bay for $68.00 shipped. It was re-built in China and chromed, puts out 110 amps, works fine for now. It is on my Garage Art motor, the motor in my Jeep has an auto parts store re- built one wire on it, I never have any trouble with it. After I start my Jeep I gas it up a little and it starts charging and works like any other Alternator. I found a 5/8" pulley for mine so I can use the larger factory belt on it.

 

Note that the kit to make a 1-wire from a 3-wire can be easily purchased. These Delco modular alternators are really easy to overhaul, so conversion also should be easy. (I don't see much reason to go 1-wire. You can tie the sense wire right back to the charge wire like Jeep does, and that means there's only 1 more wire to run). Supposedly a 3-wire will work as a 1-wire - tie the sense wire to the charge wire, and leave the field wire floating - but it requires a lot higher RPM to start self-energizing from the residual magnetism in the field steel. I presume the 1-wire electronics uses some special circuit or semiconductors so that the self-energizing starts at a lower voltage. Apparently it still needs to be goosed some before it self-energizes. A 3-wire takes power from the ignition to energize the field at startup, and charges right from start-up.

 

I’ve personally had a field charge wire fail (go go rust belt) and cause a non-charge on a vehicle. Removal of one extra failure point is meaningful gain, I think. It’s just one more thing that can fail.

 

Unless your battery is dead, which is one reason why I'll stick with a generator.
Another reason is that newer alternators can self-destruct if asked to charge a low battery.

 

Embrace the diode! Get in touch with your inner semiconductor!

Really, they used generators in the olden days because there were no semiconductor diodes then. The 3-phase alternator is way more efficient, and your battery has to be 100% flat so that you can't bump start and charge.

 

But if its about being modern and efficient, why drive jeeps to begin with?

 

Getting more done with less is efficiency. Old Jeeps get a ton done without all the crap of newer vehicles lol

 

I see no problem with adding an up grade to my old Jeep, like an alternator, as long as I have the original parts for nostalgia. Almost every old tractor I see at tractor shows has an alternator on them, it is just better than a generator, and it really does not hurt the value of them.

 

I use 1 wire alternators on all my farm tractors and Jeeps and everything else. When a gen fails I just give it to a friend if they want it. The only one I ever had that worked is still working on the Ford 8n. It knows it would be gone if it gave me nonsense. I just go right to the parts store, even Autozone will have a 1 wire. I just ask for an alternator for an 85 Chevy truck. I do like the way a generator looks on a real restoration though. I can see both sides I guess
