Anyone good at electric?

You know, they sell those that don't require assembly.

The ad photo is not so matched.

This is the real item photo.

This photo shows it right.

No idea what OP is trying to do. But I agree, buy them with the wires already soldered on.

Cigarette Lighter Plug Cable Car

My experience with these things is buy a lot of fuses. You are sure to blow them.

Thanks for the quick reply.

Here is the ad pho

I just can't trust this photo. The arrows for the screw cap and spring are wrong. And when I opened it, the spring and the fuse switched in position.

Here are my questions:

1. There are two curved copper pieces. It supposed to be connected as negative pole. One of them connecting to the positive pole through an electric resistance and the RED light, one of them is stand alone. Which one should I connect to?

2. Should the fuse connect to the "contact head" or the spring connect to the "contact head" ?

The original one to be replaced by this item is very simple. The two side curved copper is actually one piece of copper as negative pole, and the positive pole is directly connect to the "contact head". No light, no fuse. With the new item, I have two pieces of curved coppers, and they're not connected. It seems totally different.

All is OK except the spring and screw cap labels are reversed in error.

Where did you buy this from, Heath Kit?

Give or take the wire coloring code....  Whichever wire went to the center in your old connector is the + wire here.

I just stopped by these forums after a long break - it looks like the OP was trying to repair something.

Just for future reference if others show up, my personal recommendation when trying to repair somethiing like this:

Cut the wires

Put Anderson Powerpoles on the cut wires

Buy a preassembled cig lighter plug to Powerpole adapter, or buy a lighter plug with cables preattached and terminate Powerpoles onto it.

I have an air pump and a portable cooler that now both have Powerpoles, and can either be powered by a CL plug, or a big 200+W 12v supply.

Anderson Powerpoles have become the de facto standard for amateur radio emergency service 12v power wiring.

I gave up already. I finished the welding and my efforts didn't pay off. It didn't work. The welding work is pretty hard. I don't need the LED, don't need the fume, they make things complicated.

I am thinking to buy another one. I bought this one in eBay because of its high amp number. Others seem too delicate.

I was thinking to buy another compressor instead. But I don't use the car so often now because the pandemic. I have time. So I can make another attempt.

Let me know if you have any recommendations. Thanks.

Don't always believe specifications. As the poster indicated, the design of this is such that the high amperage specification is questionable due to the spring carrying current.

I know I found a reasonably well-designed plug somewhere, but it's been nearly a decade since I replaced the plug on a thermoelectric cooler and I don't remember where I got the replacement. I'm pretty sure it was using screw terminals or crimps for the high-amperage wiring.  As I said, I've generally moved to using Anderson Powerpoles, and an off-the-shelf (from a trusted source, Powerwerx) pigtail to go from a cigarette lighter socket to Powerpole.
