Minimuim Electrics XS1100

I think that would be correct 

[excess.11]

The schematic Miti posted would relate to how 2 switches ....or more....can operate one load. In your young mind Bretto....would it have related to the front and rear brake light switches?

[BrettS]

Just reviewing the Minimising of wiring and I have no idea what this younger version of me is on about Oh shit I hate electrics!
Oh and thanks Miti, sorry I have no idea ? Looks very understandable in your diagram but cant remember how this relates to my issue in real life

[Miti]

If someone could have a go at explaining how the double switch on one light circuit works that would be much appreciated,

The switches are wired in parallel - across each other.  It doesn't matter which one is closed or even if both are closed at the same time, the lamp should come on...

Here's a similar circuit:



L1 and L2 are the supply and earth.  This circuit has a siren instean of a lamp, but the principle is exactly the same.

The "signals" circuit on a standard XS11 is fed by brown wires from the fusebox.  The brake lights are green/yellow... When these two are connected by either switch, the brake lamp should come on (providing the bulb has a good earth...)

Hope that helps

Haha, When I couldn't find a ready made spot or bracket to mount the resistors I put that on the back burner, other jobs are getting urgent. LED's at the back and ugly little globe indicators at the front for now but I think it is ready to be legal again.
Thanks

You re a glutton for punishment Brett.............

plural gluttons for punishment)

Damn I was hoping I would beat you to it and save you the trouble. Thanks Jeff.
Following the brown wire I found it was connected to a earth, this resulted in a short of course. Found any old power wire connected it too the tan wire and bingo, almost, I then found the switch on the aftermarket brake was not disengaging. As in the lever was not pushing the switch in enough so the brake light was staying on. Sheesh  . Tried a few fixes but ended up gluing a little extra plastic to the switch so it was getting depressed more. Now Bingo.
After reviewing the oil level light thread I decided to just wire up the old oil pressure light for now. After some F,ing around I found the red black wire had a bullet connector, not connected around the fuse box area and then bingo.
So almost done for now but going to play around with the LED resistors and add a couple more LED lights.

Both the front and rear brake light switches work by a tan (switched pos) wire to each switch.............and a common....... green/yellow from each sw to the rear brake light globe . The brake light globe has a black (neg) wire to it to complete the cct.

[BrettS]

Following this diagram CLICK it seems to me the power goes into both switches brown and comes out green. The brown power in comes at some stage from the flasher unit. My flasher unit is now only a two pin, maybe this is the problem.
I am about to fit the resistors for the LED flashers which should mean I can go back to an original flasher unit.
I am also thinking that I could just power the loose flasher wire from some where else but none of this explains why connecting the front switch wires stops the rear switch working??

[BrettS]

That's Great Nozi, next time you have the tank off could you post a couple of pics so I can get an idea of how much wirring is left and what App's you have removed?

Jeff the Neutral worked when I put negative to the switch and the positive straight to power, thanks 

So that is about it for the speedo, the only thing I haven't hooked up yet is the oil light. I was just about to review what a couple of you have done with an extra idiot light and I might hook that up to it.
A few less wires than the average XS

The plan is to just cable tie all the wires that are left at the moment so I can get my hands on any more unwanted in the near future, Notice the CDI has been moved for a low racer seat.


Still one electrical problem I should tackle. I don't think I have ever had the brake light work from the front brake, not as long as I can remember anyway? If I hook up the wires I believe to be for that to the aftermarket, HONDA ? brake handle switch then it does not work and it stops the rear brake switch working.
If someone could have a go at explaining how the double switch on one light circuit works that would be much appreciated, Jeff 
In the mean time I will review the Wiring diagram again

my xs1100 is a cafe racer and i used that minimal diagram posted as a guide to chop my wiring. this was quite a while ago, but bike starts and runs fine - i kept the turn signals.

[BrettS]

Much appreciated Jeff, I just did a mock run with the diodes and that seems to have solved the problem for now. Maybe your way will be better as I simplify more and more, but as you say hard to explain ?
I also got some resistors for the LED lights, they are chunky and cost $26 (will get to 170 deg so must be careful where you mount) but I can now use the original flasher unit and the LED flasher cost me $36, shorted it out once and it blew. The $2 one I got from ebay is not doing a good enough job with the newest LED's Should have just gone the resistors to start with it seems.
I think I am set to solder everything into place fingers crossed will be done today?

[excess.11]

Brett....single idiot light needs to be connected to the output on the flasher can.....or whatever your now using for your led flasher unit.
Do not connect both to the idiot light as this is where both left and right are picking up a common voltage to all flash together.
I t s a pain trying to sort electrical probs online as there are many things not seen and said in trying to cure the problem.

[BrettS]

Hey thanks Jonesy, I think what you refer to is a diode, love your explanation of them. I found out about them here
http://locostbuilders.co.uk/viewthread.php?tid=170317
and now you have confirmed it.
I just went and stripped every wire I could find no longer in use and I now give up on the notion that it was working before and I was heading back to look at what these diode things are, will have to go hunt the town for a few.
This does not save the wiring from my wraith 

[Jonesy :-)]

Hey Brett
on the XS I owned previously I went to one idiot light for left and right indicators, but I had to put the electrical version of a non return valve in the wiring,  to stop 'em all flasing like hazard lights, name escapes me what they call it.......a resistor maybe?
