My diesel 1050 Bolens already has an electric starter on it, but the engine never came with a charging unit.  I am trying to combine Bolens Equipment with this Lombardini Diesel Engine to keep this as close to original looking as possible and so far its coming along great and I have had it to one show so far, but I was barely able to get it going at that time and now I am trying to refine some things to make it better.  I just completed the pto drive pulley setup today to use attachments if I want too and now I am onto the charging system for the tractor.  I am in the process of mounting a S/G on it and already have a wisconsin s/g pulley mounted to the engine.  I would much rather going this route rather than using an alternator because my funds are somewhat tight and I have a couple extra s/g laying around.  Has anyone ever used a s/g as just a charging unit? Or does anyone know how I would wire one up for just charging? I have plenty of used Bolens wiring harnesses to complete the task, but what would I have to change to make it work?

Might be better off putting a small cheap 1 wire GM Alternator on it with internal voltage regulator.Seen them for sale for $40-$60.Basicly the same price as a Delco Regulator.

 

Ebay has them for $60 shipped but you can more than likely find one cheaper locally.

How do you like that little Lombardini 6ld360 6.4-7.5hp @3600rpm 12.36ft lbs @ 2200rpm diesel?

 

It's 6.4-7.5 hp depending on the DIN

N DIN 70020 7.5hp

NB DIN 6270 7.0hp

NA DIN 6270 6.4hp

Go to a salvage yard and pick up a GM alternator, as mentioned above,  off a smaller car.  Your S/G set up will only be putting out about 4 - 6 amp and will be pulling all the time.  An alternator will pull when it is charging and run idle when not.  You will be much happier going the alternator route.

If you want the look to be original but the functionality I have heard there are alternators out there that are encased in a generator housing for the look.  I guess there are guys that use them on old farm tractors for reliability but wanting the original look.

I guess I'm not sure what you are asking. 

Looks to me like you hook it up as it would normally be and it should charge. 

You just won't be using it for starting so leave the wire off from the key switch to the SG.

I thought it would be more expensive than that......so, would it be as easy as connecting the one wire from the alternator to the battery to charge it then ??  Also the diesel is absolutely awesome, maybe could use a couple more hp, but other than that it performs well.  I dont really plan on running attchments but, the ability to do it is what I was looking for.

I believe it would work just fine. You would need to imitate the wiring from the original (excluding starter line), but other than that?
That's IF you want to stay original looking. If not, eBay a SG unit and fund the alternator.

As for the alternators...
The 10si alternators work very well. I have two on tractors here at the farm.
I don't use the one wire versions. There is either a constant draw on the battery (some guys run them thru key switch to avoid, but that's hard on switch) or they "slam" into charging.
The 10si was designed with a resistor lamp in the feedback and excite circuit. If the circuit isn't there, it may still activate, but it hammers into charge mode in a way that they isn't designed to do and causes a more substantial initial voltage surge.

I know guys are using them and loving them, but the research I did when considering them made me a believer in hooking them up the right way.
The correct way to wire them only uses a couple more wires and an idiot light. A few dollars and a little time is worth it IMHO.

If I decide to use this alternator setup, I am going to need some help wiring it up, as long as someone can show me what to do, I think I can do it.  Maybe a wiring diagram of sorts.  I never wired an alternator before but it sounds like a good idea.  As far as what I have for wiring now all I have is a regular battery and the main lead is going to the starter and then I have a fused wire running from the battery to a push button switch that then goes down to the starter solenoid which cranks the engine over and thats it.  All I need for the charging system to do is just charge the battery.  So If someone can show me how to wire the alternator, I think it should work fine.  Another reason I was going to use a generator is because thats what came on the tractor back in the day, but im not the greatest at electical work.....

The sg wiring diagram would be in the shop manual for your model.
As for alternator wiring, as long as its internal regulated, it will be easy enough.
Heck, this guy did one

The new alternator all hooked up and charging. I need some help though... due to the alternator having a self exciting system it seems to be applying a charge while cranking to start, causing the tractor to not turn over fast enough to start.  I need to not have that happen so it doesn't cause the battery to drain so quick so I thought about maybe putting a start solenoid in between the contact of the alt and battery and once the tractor starts, have a switch to send juice down to the solenoid to connect both sides of the charging wire to charge, but i am concerned about over heating the solenoid due to power always being applied??? Any Ideas?? Or do you think the solenoid idea would work???

That alternator shouldn't charge till it sees 12v to the ig. terminal. This should receive 12v when the key is turned on, the third terminal is for a dummy light on the dash.

 

The B terminal should be connected directly to the battery positive terminal.

 

I don't think those will 'self energize' in stock form.

Some alternators will get damaged if they are spun fast, without being connected.  ....I don't know if your alternator will be affected.

 

There are solenoids for continuous duty or intermittent duty.  ...If you use a solenoid, you want continuous duty for what you are trying to do.

 

A normally closed relay could be used in place of a solenoid.  ....A wire from the START terminal of the switch or from the starter, would activate the relay, which would open the circuit between the alternator and the battery only when the starter is being activated.  

 

In one of your posts you said: "...for wiring now all I have is a regular battery and the main lead is going to the starter and then I have a fused wire running from the battery to a push button switch that then goes down to the starter solenoid which cranks the engine over and thats it." 

 

Your wiring should be:   Battery to one side of the starter solenoid.  ....Other side of the solenoid to starter.  (Use battery cable)

This other wiring is correct.
