Default Ground wire on battery

Am I the only dummy that broke the little wire on the negative lead to the battery? I know it looks ugly, but I got it recrimped without adding a wire. I noticed that the original was not soldered so I didn't do that. The tape was just in case. It is actually crimped pretty good after the third attempt. Can a new wire be sourced? Is it a pain to change? Any reasonable alternatives? Asking just in case. I should have removed from the terminal prior like last time. It was out of the way but I slipped installing the new battery.

Lots of us have managed to break the too short sensing wire. It is important for proper battery charging.

There's nothing special about the wire. Just splice in a section of black wire about 14 or 16 gauge. Solder for the best electrical connection, then use heat shrink insulation or tape over the joints.

Thanks for the reply. I didn't want to alter anything out of fear that I could mess something up. This is good to know for the future. I may go back at some point and solder in a wire so there's more slack.

the real question is:

has anyone found a correct connector crimp lug of the correct decisions, ie: wire size, bolt hole opening etc.

Not some germeric part that kinda fits.

if so, where?

This is what I would do. Shrink wrap is great and will last the life of your vehicle

Amazon is your friend lol lol

OP, there is a reason that it's not soldered, in this situation a well-done crimp connector is better than a soldered connection because vibration can "fatigue" soldered connection

Thanks to all but how about soldering the extra wire to the existing then crimping the terminal?

You could because it's so small but a proper and I stress proper crimp connector is a better solution

That is what I did but didn't add an extra wire. Pain as it is so short. But seems fine after two days of testing.

Mine was broken when I took delivery of the car. On the 170 mile drive home I kept getting charging errors so I took it into my local dealer the next morning and they repaired the wire by adding about 4 inches of wire so there is plenty of slack and it hasn't broken again in the following 8.5 years.

While I have not broken the black wire, there have been a number of posts on the forum of owners that have done so. What Ron says is correct.

Correct way.

ie:
To properly repair broken sense wire:
Solder a black 16 gauge ~ 3 to 4" long extension wire, use heat shrink with sealant inside to cover the connection, then crimp on a new ring terminal at the exposed end using the correct controlled crimping tool.

Soldering is never recommended for any application that is subject to vibration as it will fatigue. That's why a butt crimp connector is the recommended fix. Have you ever seen any connection "soldered " in a motor vehicle?

Never thought about it like that. Good point.
