Hi, I'm just in the process of fitting a Sachse electronic ignition to my Guzzi, and would like clarification of how the wires attach into the fittings provided?
 
 
 
Would I be correct to think that you push the wire into the fitting (from the black shoulder end) and then put this into the "electrical block" and then screw down the clamp to lock the wire and fitting in place on the alloy tube part with the bare wire trapped inside? I did try a quick solder of one, and the black plastic nearly melted off, but when I pushed the wire into the fitting and then tried to clamp it into the block, it seemed that I needed to use quite a lot of force.
 
In the instructions that are translated from German to English it just says, "always use end splices."
 
Sorry about the poor quality photo.

They look like push in spring clips. Generally these work best on thicker single strand wire, but I would solder the strands together at the end to make them rigid before inserting them. End splices might mean those little tubes which are often crimped over multi strand wires. Solder does the same thing.
 
However, I have never seen the Sachse unit so I might be completely wrong.

Thanks for that info Brian.
On the adjacent side of the long black plug are a row of small screws which you screw down and the plates under them clamp the fittings. I suppose that there wouldn't be a problem soldering the wire, inserting into the fitting and clamping down directly onto the wire and excluding the "tubed fittings."
 
Thinking about it, maybe you strip more insulation off the wire so that the copper wires protrude out of the end of the tube and then by folding them back over the fitting, this would help secure it all?
 
I'll have another look at it tomorrow.
Thank you again.

Had to Google "end splices" - looks like you need a special crimping tool. No those 'tubes' are not soldered, but crimped onto the bare wire (no solder).

If the block has screws, then I might think in terms of just inserting the wires although instructions say not to. But soldering the ends first might help.

Thanks for that Mike.
I do have a couple of crimping tools, I'll have a look at doing this as well.
 
I might ring Gutsibits as they sold me the system, hopefully they'll know?

Right so, it looks like these things are called "bootlace ferrules" -

The crimping tool for them (page 2) is £42.76 (!)

I wasn't suggesting soldering those bootlace thingies onto the wire, I was suggesting soldering the wire to make it stiff instead of worrying about crimping and all that entails with specialist tools.

Thanks for the research and the advice, Mike and Brian.
I spoke to Ed at Gutsibits and he was unable to advise as he had not personally fitted a Sasche EI.
 
What I've done is used my existing crimper to crimp the wires to the fittings using 2 x flat faces. The connectors still fit into plug but are just short of an interference fit. The wires are captive in the fittings and so I can't see there being any problems.
 
Thank you.
