Cheap Sh775

Looks a good one https://www.ebay.com/itm/32351094643...&ul_noapp=true

Yes, it does.

Surprised it's still there.
Meanwhile on the stall beside we have this trap for the unwary.
A new RZR800 unit for $31 and free shipping..............
At least this one doesn't claim to be a direct replacement for the SH-775.

You have been warned

My electrician and go to electrics guru is of the oppinion that the SH775 r/r unit (the real ones) are so good that, buying a used one is a smart bet. So, since he has yet to steer me wrong, bought a used one exactly like the linked one off a damaged snowmachine for about the same price. In combination with a clean harness and direct to stator wiring and the posplayr SPG model... seems to give me voltage numbers that are so good & consistant that they are boring. (boring is good)
Anecdotal yes, and have not yet had several seasons of success to boast about but... so far, by the numbers it's solid and confidence inspiring.

What you electrical friend is describing is what is known in reliability engineering as the bath tub effect and infancy mortality. Basically the used sh775 is very reliable because it was in service beyond any initial break-in that might have caused failure and it is in the flat portion of the bath tub where there is s very long useful life. This apples pretty much to anything electrical but especially the heavily potted packaging. So the same for the compufire as well. Anything that gets hot will wear out faster which is especially true for the OEM units.

"...one off a damaged snowmachine for about the same price. "

What model " snowmachine " ?

[Nessism]

That unit looks like a great deal.
I had some ebay bucks to spend so I snatched up a couple of cheap SH775's recently. I'll test them to verify function and then offer them up here. Some guys get freaky about buying used parts but these used SH775's are low risk for sure.

The name is derived from the cross-sectional shape of a bathtub: steep sides and a flat bottom.

The bathtub curve is generated by mapping the rate of early "infant mortality" failures when first introduced, the rate of random failures with constant failure rate during its "useful life", and finally the rate of "wear out" failures as the product exceeds its design lifetime.

In less technical terms, in the early life of a product adhering to the bathtub curve, the failure rate is high but rapidly decreasing as defective products are identified and discarded, and early sources of potential failure such as handling and installation error are surmounted. In the mid-life of a product—generally speaking for consumer products—the failure rate is low and constant. In the late life of the product, the failure rate increases, as age and wear take their toll on the product. Many consumer product life cycles strongly exhibit the bathtub curve.^[1]

Which end is the plughole at

"...one off a damaged snowmachine for about the same price. "

What model " snowmachine " ?

I belive they were fitted to a ski- doo not sure of the model and they are labelled with SH775AA

Makes sense to me... thanks for giving the concept a structure.

My mistake, it's a suffix BA from a Polaris Ranger... when I see "Polaris" I automaticaly think snowmachine. What it came out of was less important to me than that stamped image on the side identifying it as the genuine article.

All of this was just to point out that in my experience, a used one worked out great & cheap.
Why a used one is a good gamble has been illustrated in the cool bathtub chart.
Why I mentioned it is; because used electrics in general are percieved as risky and I though I would share my positive experience.

Is there a difference between SH775AA and SH775BA? I am shopping for one for my 85 GS1150E.

There is no difference as far as I know. The BA always has the Polaris part number while the AA always has the SeaDoo part number.

Apparently, the seadoo part# is 710001103

Annoyingly enough I made an offer on that particular SH775 but it was overnight in my time and I missed their counter offer, and someone did a buy it now at the full price and I missed it... I know for next time now just to buy it! Unfortunately it seems the shipping prices have become obscenely expensive... some sellers are up to $US50+ to send an R/R to Australia now! Still cheaper than buying a used one locally though... if you can find one...
