I started a thread on these quite a while ago, they can be a big issue not unusual for corrosion to set in and if not fitted correctly can actually cut wires. Rack them off and do a crimp join.

I didn’t realise it was the same product as your thread till I was on the jcar website lol is this one a better option?

Crimp Wire Connectors - 2 & 3 wire - Pk.8 | Jaycar Electronics

Not familiar with those, I just use the normal crimp to suit the wire size, one of the secrets is to have a quality crimper.

This is my collection of fittings I carry everywhere JIC. These are my crimpers with interchangeable jaws. All work together perfectly.

Neat set up bud, which one of those would you uses when you want to join the end of a wire to the middle of an existing wire.that’s what’s happ

I have crimp connectors that are bigger one end than the other so one wire in one end and two wires out the other, there is a good array of connectors available. Have added a lot of electrics over the years, only Issue I had was with day lights I fitted and used one of those crap things to pick up power many years ago, never again.

Depending where the wires are I also use heat shrink.

Wow you are prepared af, I have soldering iron at home. I plan to get the crimps soon ish. I pushed the wire back into the dodgy connection and the Parker’s are working.

I guess I have a electrical short some where I’ll sort out soon. I’ll replace all those connections one day because the indicators stopped working on front bar and the Parker flashes with indicator lol but I’ll sus it when weather improves

Soldering connections comes with its own issues, I was a dedicated solderer for many years until becoming the owner of various boats and doing mods and also talking to various people and hearing their issues, one of those is a member here ( @OldMav ) and at the time was a boat builder. Crimping with quality tools gives the best overall results, I also coat the parts with dielectric grease before crimping ensuring good contact. Using heat shrink is always a good idea for ongoing strenghtening and protection of the wires at the crimp zone.
My 2 cents worth.

Solder all the way. Quik easy n simple to do, if done correctly. After 10+ yrs in the 4wd industry and 47+ yrs of life. Its the best way to join wires together. Ive seen solder joints survive 20+ yrs in old mq's
but crimps failing after 1yr. Again its all in how u do it and quality of the equipment u choose to use.

Never had a quality crimp fail, but have had 'dry' joints in solders over the years.
I'm a 76 year old fitter machinist/engineer 😉.

There are many reasons why a dry solder joint can happen and yes doing it incorrectly is a contributing factor, incorrect iron temperature, holding the iron on a new joint for to long burning away all flux, but mechanical actions can also contribute, fatigue from cyclic loading, vibration, corrosion, etc.

Another factor we need to consider is the experience of our members attempting these jobs, this is the reason I recommend members buy quality crimps and crimpers, much easier in many ways, including mobility and preparation.

I have built many electronic devices for my and other members patrols but they all finish up being connected inline through crimps.

Have you got a recommendation for a 'quality' heat shrink?
I have been using the cabac dual wall (glue lined) stuff from the local electrical wholesaler but I'm sure there is better out there without going to raychem dr-25.

I just use heat shrink from JayCar, both plain and glued, no issues so far.

While we are on the subject of how do these work, while doing a repair on the underwater pool light yesterday I went to my container of connections and the below were in there, I put them aside to investigate later. I have a recollection of them coming with something I bought, but obviously didn't use. Before I throw them in the bin can anyone idenify them? They have 3M written on the red area.

 

[geeyoutoo]

I have some, they were given to me by a Telstra tech. He used them for joining phone cables and insulating end runs that were ‘live’. Never used them.

Cool, thanks, in the bin they go, must have gotten them when I installed router.
