Alternator - bare wires

[Phil C]

The solder wire I'm getting has a flux core. Do you think that's enough? Hopefully, if everything is clean. I remember cleanliness being crucial in soldering.
Thanks for the tip about Rupert Ratio - I'll have a look.

Even with a flux core I would still use flux. Applied with small brush it gets in amongst and cleans the separate strands of the wire. You can get little tins of flux in B&Q.

Actually, yes, that's what I'd have done when I worked in a workshop. I'll get some passive paste as well.

Evening all, My soldering iron arrived in the post today, so tomorrow I'm going to have a go at removing the old wires from my stator, and replacing them with nice new ones. Having a look at the stator just now, I was a bit confused (no surprise there, I hear you say.)  Please bear in mind I know virtually nothing about alternators. Anyway, what struck me as a bit odd was this:  the three wires should each be attached to the winding wires. Right? One of my three wires is already disconnected, the other two not yet. But (see photo) it looks to me like the disconnected one must have been attached to just one winding wire (see  it in the murky darkness, foreground left), whereas another of the three (green/yellow) seems to be soldered to two winding wires which can be clearly seen running parallel next to each other. The third one I'm not sure about. In my ignorance I'd have thought that each of the three wires should be soldered to the same number of winding wires, be that one or two. Could someone explain please? I'm praying all is well and that there is a simple answer!  Phil.

Hi,
     There are 6 coils arranged in pairs. One side of the 2 coils (1 pair) have a green/black wire, as are the other 4 coils (2 pairs) are joined by a green/yellow. The other side of the 6 coils (3 pairs) are connected to a common white/green wire.

Best wishes...

Thanks Bess. Let me check I'm understanding this right. My new green/black wire should connect to one single strand coil wire at the stator; my green/yellow to two coil wires; and my white/green to three coil wires. Is that correct? Phil

[Phil C]

Further to my previous post, yes, that seems to make sense, even to me. It's about output control, yes? All three pairs connected to one wire, two pairs to another, and just one pair to another.   Phil

Funny thing. Soldering my new wires onto my stator, the one that went to the three coil wires was fine, so was the one that went to two, but the one that went to the single  wire kept being contaminated, black muck in the joint when I was soldering. Re-did it several times. Flux-cored solder (I think it's lead-free, judging by the full finish of the joints), flux paste as well,  cleaned the single wire  (emery, wire wool, carb cleaner), tinned it, clean hands. Can't make it out. Seems to be a secure joint, but a bit annoying. Any thoughts?  Phil

Oh dear, it broke.  The actual winding wire (single strand), with its new multi-strand wire soldered to it, broke. Maybe not supported well enough? A bit disappointing. I'll solder it again, but I'm wondering is the single strand is strong enough to bear the weight of the new wire and solder. Any advice anyone please?    Phil.
