R/R , correct part?

[Guest]

I bought an Electrosport ESR090 for my 83 GS850G, the wires seem to be different colors and I think the original has a few more than the replacement I wanted to put on. Could I use this one? or should I use another?
I tried to do some research on what has to be done, I couldnt find anything.
Has anybody used this part, and could walk me through?
It would be much appreciated!

Yes, you can use that unit but it's inferior to the forum favorite, the Shindengen SH775. If you can return it I'd encourage you to do so, otherwise wire it up like most other 5 wire R/R's.

Route the stator wires straight into the R/R (bypassing the factory harness). The stator wire colors are meaningless since all have the same output, but regardless, feed them into the yellow wires on the R/R.

Find a clean frame mounting point for the R/R ground, or go straight to the battery.

For the + output from the R/R (red wire), either go to the battery + post with an inline fuse, or feed into the fuse box directly. This terminal should be a round bullet. If you go this way be sure to check for resistance in that wiring leg using the method detailed in the Stator Papers troubleshooting guide.

Good luck.

Uggh, why? How did you miss all the stuff about series r/r's?
Did you miss this?

If your original has more wires, maybe it's a Shindengen with a sense wire- any markings?

I need to do this. I need to read. I need to know.

I just wanted possible plug and play, I'm going to try to return this one. I dont want all extra fuses etc if I can get around that.

Forget plug and play. You should bypass the factory stator wiring and get a SH775 if you want the system to be reliable. If you don't want extra fuses send the R/R out into the fusebox like already mentioned.

Ok, and I'll be able to get everything going with the "FH012/FH010 Connector Kit" from EasternBeaver?

[cowboyup3371]

You'll also do fine if you get the connectors from them only then buy your own 10-gauge wiring so you can tailor it to your actual needs. I did that and the layout worked much better for me.

[phydeauxmutt]

You can also get the wiring adapter kit for a Triumph motorcycle for about half the price of the Eastern Beaver kit.

By the way, the last R/R I saw on an '83 850 had 5 spade terminals lined up on one side of it. Yours like that?

[Nessism]

Do a search here and look up the Triumph harness part number. It's something like $10.

No disrespect intended toward cowboy scott but you don't need 10 gauge wires for a GS charging system. The system maxes out at something like 15A. 14 gauge is plenty and easier to work with.

I just installed the compu-fire r/r its a little more than the sh-775 that is the forum favorite but once the triumph harness, + r/r, and shipping is factored there wasnt a whole lot of difference in price in i think i got the compu-fire for $139 and amazon prime free shipping. See my thread about charging issues and the last two pages I tried to upload photos, so far its an awesome upgrade from stock.

I have installed both the Compu-Fire 55402 and the SH-775 on my GS's. The CF is big and seems well built, I got mine about 2 years ago on Amazon for $169 shipped. Agreed that the 10 gauge wire is overkill although I ran mine all the way from the battery/stator up to right under the neck, above the oil cooler on my 83 750ES since that's the best place I could find to fit it, so the bigger wire was nice to have.

The SH-775 is even cheaper when you buy one used from eBay from a wrecked low mileage/hour Polaris Ranger or Rzr. That's where I got my last one I paid less than $40 for and the Triumph kit is money well spent but I've even used female spade connectors in a (temporary) pinch. It will fit in the factory spot under the battery box on an 850 with the connectors facing the left side of the bike where all the fuses and wiring is, if you elongate one of the bolt hole slots a bit, or just fab up a quick bracket with a piece of steel or flat aluminum stock like I did.

Although it's not truly an apples to apples comparison, but my vote after having installing and owning both is for the SH-775. Cheaper, smaller and with "side by side" testing on 2 similar vintage bikes, I get better charging voltages out of the SH-775 across the RPM range. The CF 55402 stays just under 14V from just above idle all the way up to redline and my SH-775 (on a bike with 40k more miles) does drop to 12.7V at idle (with a lot of extra lights and heated grips on to be fair) but at ~1500 all the way to redline it's at ~14.4V. I use the same cheap eBay LCD voltmeter on both bikes, have switched them and have basically the same wiring location for both.

[posplayr]

How do you figure the sh-775 is smaller than the compufire?As far as the sh775 producing higher voltages that is probably due to bike specific issues the voltage losses and power losses of the cf are less than the sh775. Sure the sh775 is cheaper but that is about the only benefit other than perhaps having a much larger presence in the used market.

[mikerophone]

Ok, not smaller, narrower and not as tall so it still fits under the battery box on my 850. The CF wouldn't - too tall and the bolt holes were further apart. I was able to ream out the slot on the SH-775 and fit it in the factory spot under the battery box, at least until the bolt hole threads stripped out due to being a rust encrusted nightmare. Cleaned it up, made a quick bracket, re-tapped the bolt hole, coated it all with POR-15 and all is well.

I'm sure you're right on the bike specific issues, and my comparison is definitely not a very good test, because both bikes are of course going to be different even if they were the exact same year and model with the same miles on them and they were owned by different owners and surely encountered different environments and charge/discharge scenarios. Regardless, I've owned them both and put ~8-10,000 miles on each after having gone through the wiring - cleaning up and deoxidizing/coating the terminals and connectors, testing resistance and voltage drop, re-flowing solder into the fuse box, etc., all of the above because of you and your posts, but for me ~1/4 the price with similar performance is the better option.

When I just mounted my CF, it fit perfectly under the battery box, I had to fab a bracket to mount it due to the bolt holes being a little longer by 1/2 an inch or so
