Regulator / Rectifier GS750 (1978)

[Guest]

Hi, its been a little while since i have been on the site, but i wonder if you can help.

I have an issue with my bike not charging & strongly suspect the rectifier / regulator.

i am looking to replace it with one of these?

Stupid question, but does this replace the both the regulator & rectifier as the current one fitted in in two parts?

Thanks

Ir replaces both. Connect the 3 output wires of the stator to the 3 yellow input wires on the R/R.
Red is 12V out and black, is ground, of course.

Not stupid at all ! yes, that R/R would replace the two seperate units, BUT it's a poor choice! go here ,do some reading. (Hint = SH -775 R/R )

If you get bewildered, come back with questions

That was quick, thanks both.
I'll have a read of the posts tonight

tom, I see he is in the UK. Is that R/R available over there?

If you can get the SH -775 in the UK do it. It's well worth it.
It's quite large and you will need to modify the mount location. Mine is on the bottom of the battery box at an angle.

Well, I figured Polaris would sell ATVs there to herd sheep,etc. If Pete can get one in the land down under, I imagine he can get one. Besides that R/R that he linked to, seemed cheesey- with the SH numbering scheme.

Motolodge, whatever that is.....

You will find five wires coming from your stator. There are only three, two of the same color wires are twinned to go to both regulator and rectifier. The one that takes off in a loop through the headlight switch should go directly to the new R/R abandoning the loop. You will like the results of a series R/R, it will eliminate all the problems caused by the old shunt type R/R's.

OldVet66, I find your post confusing, and I have been around for a while.
Could you please explain in different words, such as:
There are only 3 wires that go from the stator to the R/R.
Although there are 5 wires coming from your stator, 2 of them are duplicates and can be combined together with their twins, which are the same color, resulting in an overall number of 3 wires total.

Something like that.

[OldVet66]

Three wires come from the stator, two have a wire of the same color of that wire soldered to it so you see five wires. Suzuki abandoned the separate regulator and rectifier setup after 1979 for a combined regulator and rectifier. All the stators after '79 had only three wires. Perhaps someone not particularly familiar with the older setup would be confused by the apparent existence of five wires. I know I was until I cut back into the cable bundle an found the solder point. I actually said exactly what you would see unless the stator was out of the bike.

Steve from this forum just installed the Polaris unit in my GS1100E using the Triumph wiring harness and it was pretty simple. Everything just plugged right in. The airbox had been removed on my bike so there was space to mount it to the backside of the same plate the original one was mounted to, we just could only use one of the mount holes. Now the bike is charging again and some of the other electrical issues seem to be resolved. I'd highly recommend that unit and harness.

http://www.thegsresources.com/_forum...hlight=triumph for the wiring harness. And I got my rec from here: http://www.2wheelpros.com/oem-parts/...2941-part.html Doesn't look like they do international shipping but if you contact them the might do something. If not, you could ship it to my house and then I could ship it FedEx to you, and you could just paypal me the shipping. Not sure how much it would be.
