The MGB Is Gone, But Not Forgotten

In our yard, we have low voltage lighting. Three of the lights don't work any more after only 2-3 years. I dug up the first one and found that it was tied in to the main power line with a cheap dagger connector. It's the kind that clamps on to the power cable and puts a narrow, conductive dagger through the insulation to make the connection. Water, such as it is here in the SoCal desert of San Diego, had rusted that conductive dagger to the point of dissolving.

Enter my experience rewiring the MGB. I pulled out my crimp connectors and heat-shrink tubing and voila! or should I say, "there you go!*" and the lights were working again.

My heat shrink tubing was too narrow for the multi-wire end of the connectors so in one place it required some electrical tape, but at the point, I was over the whole affair and unwilling to clip, strip and rewire everything.

Suffice it to say, my MGB wiring version will outlive all of those wretched, CCP dagger connector pieces of junk.

Bloody commies.

* - This is the British version of voila!

Yeah, I've always had misgivings about the "easy" electrical connectors like that. Sure they are fast and easy to install, but they don't make as reliable of a connection and they are setting you up for failing in a way that can be really hard to find later. And the type you describe are particularly prone to corrosion, because the "dagger" part is not copper, and combining dissimilar metals like that sets you up for galvanic corrosion if even the tiniest bit of moisture gets into it.

I hadn't thought of the dissimilar metals issue. I'm sure you're right. It surprised me there was nothing left of the dagger at all. It had simply dissolved.

This MGB is gone from us, but not forgotten, we have here a very interesting and memorable subject which has a special place in the hearts of classic car enthusiasts. Today we also see use of services like cv editing services in UAE for professional development which in turn gives us better results and strong future. This type of content which we present gives a view into the history of the old cars and their owners.
