Wiring on 1980 gs550 et (uk)

[ukjules]

I am baffled with the wiring on my bike and need some help
knowing where the wires go.
Can i add i am red green color blind so it makes it even more difficult.
I have manuals and wiring diagrams !

Pic 1:
Regulator:
I assume the 3 yellow wires from stator attach to the 3 yellow from the regulator.
Thats what happens on my kwak 750
(On my Haynes manual it doesn't even show 3 yellow from alternator or regulator)

There are 3 other wires in picture and i have absolutely no idea where they go to ?

top ? white and red - think that went to earth too ?
middle - green (with circle connector) - i had this to earth ?
bottom ? black - attachs to a 2 into one box that attaches to indicator rely

and pic 2:

On the RHS of the bike near the fuse box i have three wires again that i have no idea
where they go to ?

top - red
middle - white and red
bottom - white and green

ill try and get a better picture if needed.

(Note: the bike will start, and lights circuit works. without these three wires connected to anything.)
I dont know yet about the battery charging as need all the wires correct before i run it)

Jules I an colour blind same as you. What you have there is a honda 6 wire unit. Look for diagram in search bar.

[ukjules]

Thanks so much for telling me this - i thought i was going mad !
I have had the bike years and only now am getting down to sorting it out.

You mean I have some type of Honda regulator which uses 6 wires ?
Do you mean search on google for a diagram?

Can i make it work with my bike do you think while i wait for a proper one ?
(I am sure the three yellows go to the stator yellows (doesnt matter which to which) but the other wires i simply don't know.)

Use the forum search and look for duanage honda reg rec. I think that's how you spell his name

[ukjules]

Ok ill check
found this : http://www.thegsresources.com/_forum...onda+regulator

Do need to know what the other 3 wires are for and think this explains.

Do you know anything about the other wires from loom on the right hand side of the bike ?
these are not attached directly to the regulator they come out of the loom
the connectors on there now are probably not right too !
i simply cant see where they can go ?

top - red
middle - white and red
bottom - white and green

Read this Basscliff pdf... He changes over to a honda r/r like you have. The smallest wire will be the sense wire-

It is starting to make sense - thanks for input guys !!!

will check out tomorrow and report for follow up.
thanks

Update:

I have connected and redone a lot of the wiring in that area and now bike back on the road
and working fine

The regulator passes tests to be sure its charging.

Question:
The one problem i have is that the sense wire (the black one) is now unconnected.
I am presently leaving it like that.

This is due to it used to be connected just before the indicator flasher relay.
It like that had always caused the flasher to stop at higher revs ? as if the sense wire was interrupting it somehow ?
- evidently i have only just realized this was the case !!!
Anyway now removed the indicators work perfectly !!! at all revs.

What do you think will happen if I leave the sense wire disconnected / blanked off ?
(I am doing this more as I dont know which wire to tap it into too)

[JTGS850GL]

Sense wire??? Care to be a little more specific as to which wire you have capped off?

[ukjules]

this is involved but you have to read this first !

I am very slowly sorting the wiring out on this bike.
Regulator has been changed for a honda one - correctly it seems.

Anyway all works but the one wire is now taped up and does nothing.

With the sense wire not connected you risk overvolt and a dry battery. I have mine connected to stop lamp switch.

[ukjules]

Update - and i agree with you that one risks overvolt ........ my fuses blew 7 miles out on test run.
I am convinced that this is due to me running having taken off the sense wire to the indicator relay wire.

Went for a test ride and all fine until suddenly bike ground to a halt.
(remember sense wire was and is not connected - allowing my indicators to work)
Fuses blown main and ignition. As i carry some i put new in and they blew immediately again.
In the end i managed to put some in (there are 4) and bridge the ignition fuse so bike would start.
I have too large fuses in to get home. This is what is now that seems to allow bike to run
main - 30a (originally 10a when blew)
hd lamps - 10a
signal - 10a
ignition - 25a (originally 10a when blew) (but i bridged with wire to get home)

HOWEVER:
The bike now only runs on 2 cylinders 2,3. 1 and 4 have no spark.
What on earth can have blown ? Surely this issue cant blow any other wiring ?
plugs , ht leads, coils,
(I am yet to take the tank off and check coils, wiring etc)

Q2)
How and where did you connect to the stop lamp switch ?
Do you just tap into a power wire ?

[Grimly]

Assuming this is what went wrong...
If you don't have the sense wire connected, the regulator is unable to tell when its output voltage is sufficient and simply keeps putting out too much. The end result, if you're lucky, is a boiled battery. If you're unlucky you can cook the igniter and any other electronics you happen to have on the bike, including phone chargers, etc. Luckily, most phone chargers will balk at being fed 17 or 18Volts, but cheap ones might fry and fry your phone, too.

[ukjules]

Phone charger not connected and not issue here !

I am convinced this regulator without this sense wire cause
this issue as you say blowing main and ignition fuses.

I will inspect today but can't believe a coil is bust ?
I now have to find out how this can make it run on
2 cylinders - one coil ! Cyl 2/3 only spark .

Additionally where and how to connect the sense wire ?
Has anyone done this on a gs550 ?

Iv put bigger fuses in main and ignition ? Are they correct ?
What do others use ?


Recap:
Try and attach sense wire to a light live wire

Run bike as now is with the large fuses

Find out why a coil is not working , what could this
regulator fry before the coil ?
