Title: Warning
Post by: LarsBloodbeard on September 28, 2012, 06:16:57 am
Just wanted to share a word of warning... I just bought a "brand new" alternator from an ebay seller (Enfield County).  Now I know that ebay sellers aren't known for being the most reputable, but usually I take a bit of caution and have good results.  Anyway, this supposedly new alternator was a fraction of the cost of one from Hitchcock's or NField Gear, so I couldn't pass it up.  What I received was a refurbished piece of crap.  Rusted all over and covered in poly-coat to make it appear a bit shiny. 

I contacted the seller and told them this and they said "This is a new part. There can not be any rust as there is oil on it. We can gaurantee that this is a new product and never used. We sell them regularly. If you are unhappy, you can return it." Okay... clearly it's not new, and it's bone dry, there's not a drop of oil on it. 

So I'm supposed to pay shipping back and forth and probably just receive more crap?  No thanks.  I don't like the idea of poly coat sitting in my primary oil and possibly flaking off all over the gears, clutch, etc.  But I guess I'll run it for now and buy another from Hitchcock's later.  Lesson learned.

What is the old saying?   "You get what you pay for"
One thing I learned awhile ago (thanks again to Vince in Lacy) that for basic junk (oil filters name brand fluids) get them from a "cheap source" something that is vital for the operation of your machine obtain from well I prefer Hitchcock.    8)

This could actually be a new alternator. Lots of people make alternators for the RE. Kind of a Bad, Sort of Better and Best proposition. In general this style of alternator either has the coils encased in a plastic-like material or open like this one. One train of thought is that the plastic encased ones do not dissipate heat as well. The OEM ones are open like this one. I have seen frames that look like this even on good ones. However what you do have is a poor quality albeit cheap unit. Both Allan Hitchcock and I can buy these units for almost nothing, but why would we? You don't buy from Allan or from your dealer or NField gear for always the cheapest price. You buy because you will get what we say it is and we all stand behind our products. If we sell you a defective product or you don't like it for some reason you can return it. If it is defective we pay the shipping. As in all things it is buyer beware

I too ordered some stuff from Enfield County.  Most of the stuff seems fine though nothing is "vital" to the machine....Although the tappets cover has paint chipping off on the back side....I doubt I'll be putting that on my bike

If it is the side that goes "in" it should not be painted. For 1 it will give a Bkad seal" and leak and well if it is chipping stuff will fall in.

 Looks new to me, they dip electrical components in an epoxy or varnish. I'd run it.

Often the electrical coils on electric motors, generators and alternators are coated with a varnish after they are wound.
The varnish is then baked to dry it.

This keeps the copper wires from vibrating against one another and potentially wearing thru the insulating coating that is on the wires.

The varnish is often not applied with any great precision and it can get on the stator or rotor laminations causing the appearance shown in the photos.

I know coils are often set with epoxy (or shellac/varnish in the old days) -- I have a background in electronics -- but this thing was clearly sprayed with polyurethane or something like that.  It's not preventing the wraps from moving, and it's all over the core.
