Availability of original push-connectors


Colin Lindsay

Recommended Posts

Does anyone know if these plastic 1980s push-connectors are still available to buy anywhere? No ideas of what the name is but if I can get two (at least) I can simply join new cabling to the existing without having to attach any other kind of connector. If not, I'll just solder bullet connectors.

Secondly, does anyone know of any kind of rubber or plastic repair paint which can coat cables to repair damage to the existing sheathing (caused by scotch locks - hate those things; you can see the notches in the white / pink cable, and the black earth cable is damaged as well). I could use insulating tape or maybe heatshrink, but a brush-on solution would be easy if one was available.

Or better still Colin, why not use fresh wiring to maximise safety and prevent future electrical issues.

Concours??? Moi? I'll settle for running and driving.

Bullets are the fall-back (backstop?  :) ) as it's only the connectors for the radio / CD player, but I was being lazy and thought it might be possible just to plug in a similar male / female end as required. Fresh wiring is a possibility but at some point it's still going to have to be joined to the loom, so I'm exploring the options. I'll check out John's tape, it may be a good repair as well.

Colin,

The pink/white wire (as you know) is the correct Lucas colour code for a radio application.

You could connect that direct to the aux terminal on the ignition switch and run an inline fuse if your ICE does not have an integrated removable fuse.

As such you would not have to open up the loom if that is looming; I presume the 2x black wires are earth.

Regards.

Richard.

It exists at a price:

EDIT - This stuff is suggested on an electronics forum and is cheaper:  https://tinyurl.com/y8abg635

An excellent suggestion, my good man! It would only be a matter or re-routing the cable out of harm's way around the heater. If I'd had to trim the damaged bits off it would have been left quite short; a bullet connector would have worked ok but this will save me a bit of upside-down soldering. The black ones are earth, I'll repair the existing ones and run another to a good earth point to improve contact. Off to the garage I go to examine the ignition terminal, which is exposed as the cowling has been removed. Thanks, Richard!

 

That coating of Casper's is expensive for all I require (NOT 4 litres, which is what is on sale on eBay!!) but I'm wondering: if it's only cuts and nicks in the plastic coating of an earth cable, why not black rubber sealer from a tube? Flexible and waterproof, and a fraction of the cost...

On the TR7 the aux point is hard wired into the loom and comes out as the radio power connection. The late Lucas connectors appear to be unobtainable so most people revert to using the bullet connectors.

I think he's right. (Sadly) Back to the original plan which will probably be bullet connectors. It was worth a try though. 

I may be jumping the gun with the radio, though, miles to go before that gets to be a priority. I've found another errant blue and white cable behind the dash, near the brake switch, and what MAY be the missing green brake switch cable, which shows what you could call some slight evidence of overheating:

I suspect that's been caught in a pedal and earthed through the metal.

Correct Richard and correct Dave, both - yes there is an aux terminal which I had hoped was a spade or screw terminal, but it's rivetted so I'm afraid the only option would be to splice into the pink and white wire, which I'd like to avoid if possible as I'm undoing forty years of PO splicing. Yes, I could attach it to the ignition switch end and string an entire new cable, but I'm hoping it's sound under the protective cover and only the exposed end is damaged by Scotchlocks. I think the preferred option is going to be bullets at the business end as the path of least resistance. No pun intended!

I agree Colin, the wire should be very protected with the wrapping around it.

Toledo, 1500, Dolomites, and late Spit all have the ignition switch hard wired. I believe this is true for most 1970's BL cars.The later Lucas connectors appeared around the mid 1970's. 

Concur that the lead must be insulated from the ground or cut back to good insulation and a new piece of lead fitted.

Sorry if I interrupted the flow.

Not at all Dave, on a personal note I was unaware that the hard wire technique occurred so early.

Thanks for the info and insight.

Regards.

Richard.

Not recommended for connectors in cars these days - crimp is better.

With solder some will flow down the wire inside the insulation via capillary action, creating a hidden hard point where the vibrations you get in a car will start to fatigue the wire.  This happens with crimp connections too but they are easier to spot as, worst case the connector falls off the end of the wire.  With solder you have a perfect looking connector that may be down to just a few connected wires (increasing load) or all broken and only connected by touch (leading to intermitten faults).  both of these are much harder to diagnose and require more wire to be chopped to fix.

Good points. I was going to argue that it was only the earth connector, but then as so many electrical problems occur in our cars through dodgy earths, I don't want to add another.

I guess now I need a box of female spade or crimpable bullet connectors, so I can crimp away and get the radio connections finished and the lower dash panel back on again.

* And a good quality, ratchet crimp tool so you only need to crimp them once.
