BX25 ALTERNATOR UPGRADE

[Artisan]

I forgot to mention, a couple guys ask'd "why". I forgot I want to be able to
use a winch as well. That puppie will kill this little electrical system quickly.
I "think" remember I am horrible at electrical stuff, that if I beef things up
I will get longer use out of a winch.

OK, in post 17 I suggested Keller's site may be wrong, I called and asked and
pleasantly Brad called others and got right back to me advising me indeed the
3A011-74013 is a 60AMP Alt.

Remember the challenge tis to find a plugNplay higher output alternator.
Not take apart mine or change brackets and and and... BX25 owners
forever will reap the rewards if this is doable and w/o problems and hoops
to jump thru.

PS, KennyV, I am posting a lot of my finding in hopes it will help others.
Just maybe someone will hit upon something from my hard work.
I happen to enjoy a challenge. This is w/o a doubt "hard", espically
for an Electricaly HandiCapped Plumber!

I think the alternator you found in post 18 has a great chance of being plug and play , we just need to see the plug, you already know the front case is the same part #.

Ray, Thanx for the input. Seems like I run to this board too much for solutions,
I dunno if that is good or bad. The useless comments from the peanut gallery
really blow, why do they bother? Anyways, if this is thinking outside the box,
I fired off a RFI to DENSOGLOABAL. Who knows, maybe they will reply w/
many choices w/ part numbers. Here is what I penned to them;
Sirs,
We seek a solution from DENSO!
Currently our project has a DENSO Alternator.
We need more output from a unit with the same frame,
and hopefully same 3 wire plug configuration.
We have a large format picture of your product at this link,
this is what we have;

THE PIC IS ALREADY IN THIS THREAD

Can you Please, recommend part numbers for all higher output
alternators that will be a bolt-in, plug and play replacement
or with little plug modification?
THANK YOU!

I am not sure what to tell you -- all
I can say is that a 12k winch uses roughly 3k watts. I dont know of any alternator that will handle that as the battery will always be the buffer. I like your thinking that swapping the alternator is the smallest space upgrade you can do over adding a secondary battery that charges only when tractor is running, but a massive rewiring changes will be made to make the lights, winch, boombox amp, etc to run off that secondary battery with a backup switch to primary. If I know I will be doing this extensively daily, I would take this project on but right now, its not something I want to mess with.

So going back to alternator swapout - just looking at the pics appears it might work, but innards looks much more beefy with the electrical rectifier changes too. I'd visit your local dealer and take a peek at the current models outside.

So I have all notes in one thread, and I think a gent said #6 prior....

notforhire said; " I think the only wiring you would need to change would be the output lead from the alternator to the battery."

 

[Artisan]

If I hang on a winch from time to time I see I need a bigger battery.

I have BX25 Battery notes HERE

 

[Notforhire]

I know nothing about B size tractors.
I don't know if this may be of some help. Looking at the L3540 specs, if you get a cab model, the alt. size goes from a 40A to a 60A.
I was wondering if the same is true of the B size. Is there a B cab tractor that uses the same engine configuration?
If you go to a second battery you could install a diode set, like ones used in boats with start and house batteries. This stops flow between batteries, but allows one alternator to charge both.

Bill once agin I say Thank you for your input. Indeed should I
go w/ two batteries there will be another learning curve to hurdle.
Sure would be nice to find a monster battery to fit inside my
space, 7' x 9" x 9" is what I have and I need a 650CCA minimum
battery.

 

[Artisan]

The info I just got says the 60Amp Alt in post 18 is a different plug...sigh.

 

[Artisan]

This pic is the plug for a BX25. Can anyone tell me what the symbols mean?

P=Power? IG=Ignition? L=Lights?

 

[Artisan]

Ugghh...

The first picture is a regulator for a 60AMP Alternator that is 99% sure to bolt into a BX25.
It has two blades to the plug.

This second picture is a regulator for a 40AMP Alternator that is for a BX25.

Can I make this work by making a 60 x 40 electrical pigtail adaptor?
I need to figure out what P IG L mean ...

 

[bcp]

IG is ignition switch
L is indicator light
P is ...see page 2 on the link below

Thank You Bruce.

By the time I read through this whole thread, I was like :confused2: :confused2:

Best of luck with your project!

...

For sure....
This topic has came up in the past, several times... With direct, no nonsense solutions...
this thread changes a simple upgrade into a muddled problem. It really is Not This difficult... & has been easily completed, use the search function. The wheel has already been invented. KennyV

 

[Artisan]

Sorry I do not meet up to your standards!

Wish I was that smart, obviously I am not, if I had the awswers
I would not be here. Sorry I spoiled your TBN experience w/ my
inabilities. If someone had jumped in and interjected a solution
it would have died long ago. To date alls I can do is
post my thoughts in hopes of coming upon a solution.
I believe I have proclaimed my lack of electrical skills
some time ago. Congradulations if you know the
answers, till I see it alls I know is you know the
awnsers and I do not...

I go to GREAT pains to pay it forward on this list.
GrappleOmatic, BX25 Full Cage Rollbar and others. Is
it really to much to seek help from time to time? Perhaps
if I was just a huge vacuum on this list your "complaint"
would be warranted, the facts are I am not, thanx for
nothing.

I tend to agree with KennyV. There is lots of winch history. Take a look at http://www.tractorbynet.com/forums/customization/115104-electric-winch-advice-3.html See Tatra's comments.
You may want to reconsider. Look first, read, become educated ......

I need to figure out what P IG L mean ...

Is it possible that your tractor doesn't use the P connection? Is your tach. electronic? If you have access to a wiring diagram you could find out if P is actually used.
That alt. could be built to fit many different apps.
I recently replaced an alt. in a friends Ford tractor. The new alt. came with a tach lead. The original didn't have one.

The L is for your Alt. charge light.
IG is to provide field for the alt. and becomes hot when the key is on.

"Can I make this work by making a 60 x 40 electrical pigtail adaptor?"
I would say yes, unless there is something that uses the tach. lead.

My 3240 has an electronic tach. for the PTO. I expect that I would need the P connection on my tractor.

Now you got me curious Artisan. It's hot outside and good time to sit in front of cold computer. Looked on the web in general. People with Truck/Jeep winch questions etc. These are folks with 75-80 Amp alternators already. A lot depends on what type of winch you are focusing on.......... heavy duty, or baby ATV type winches. Here are a couple of sites with some electrical info.


http://www.jeepforum.com/forum/f27/winch-amp-draw-stock-alternator-140033/ (notable quote: You will never be able to install an alternator that will keep up with the draw an electric winch will place on the battery, this is a loosing battle.) Some of the winches will be drawing about 400 amps when working; at idle, motor only, they draw around 55 amps (Ramsey 4.8 HP series wound motor for 12K winch)

How to choose a Winch (See the section on electrical considerations).

So it all depends what you want your winch to do, if light duty work I bet your 40A alternator could work, a lot less hassle.

I am a little wiser now after doing a little looking. Good luck in your endeavors.
