What do you think about this alternator Pops ?? and everybody else.

YouTube - Ford PowerStroke Diesel Alternator "Large Case" upgrade from stock smaller 110 amp unit

 

If their components indeed are quality, and not from the "lowest bidder", then they should have a good product. Their warranty should indicate just how willing they are to put their money where their mouth is, and it looks to be fair-enough, though they give themselves a lot of wiggle-room.

The OEM alternator system is adequate to keep the batteries charged. However, unless you have unique additional current demands, high-output alternators are just overkill. Of course, around here that's NEVER considered a bad thing!

They don't mention the use of Schottkey diodes (which develop just a tad less heat due to faster switching times), which might be desirable but not necessary, and the copper vs aluminum heat sink is not a huge deal, just a small percentage different. I'd venture to say their large-frame castings are imported.

I would base my decision about using them on whether I needed the additional current to "keep up" the charge, and the price compared to a "quality rebuild".

Overall, it looks like it may be a nice unit, so long as they are reasonable in their pricing policies. If they are too "proud" of their stuff, I'd look around.

I was amused by the brand-name of their load tester in the background. Good-quality stuff there!

Pops..

I wish we lived closer, because we would make a heck of a team.

You have a lot to teach....... and I have a lot to learn........

 

As do I, and I realize that more and more the older I get!

This is sure a good place to do some of it!

Sorry for the high jack but i have a 175 amp alt. and the outside of it gets hot.First thing in the morning when i start it up with in 1 min you can hardly leave your hand on it.Is it because its a high output that's why its hot?

 

If the alternator is putting out the full 175 amps@14 volts, that equates to 2450 Watts of power that the alternator must dissipate in heat.

 

kupaa,

We'll need to know how much current the thing is actually putting out. Just because it's capable of 175 amps, doesn't mean it's actually producing it.

Besides putting the current back into the battery that you just drew out to turn the starter motor, what is using current? Anything unusual like flamethrower-like driving lamps or a thousand-watt sound system turned all the way up, immediately after startup?

No,nothing out of the usual.I bought this alternator from my friend because mine burnt up.Its a new hand wound alt,he does this for a living and test each one on a machine to make sure there working and up to specs.It was cheaper to buy this alt then get a new one from ford.

 

The glow plugs draw a tremendous amount of current.
Alternator will get hot keeping up with that.
Kupaa I know you live in sunny warm Hawaii, but the GPR still comes on I'll bet.

 

Since your friend is in the auto-electric business, what does he tell you?

And, that's a very good question by Kwik! What happens if you disconnect the wire from the GPR to the PCM, taking the GPR out of the equation?

Someone told me something. The currents from an altinator just does what it is. The currents arnt always the same. It could put out as little as 12v to 14v. It just alternates current for the demand put to it. Most of them do get hot when they are spinning as fast as the engine is turning. I know I would.

 

I don't have a clue what that means, or what you are trying to say. Sorry...
