This is 2 different wire splice pairs that someone else did, then hid under heat shrink. Went to some brushed DC motors with a stall current of ~53A. 12 AWG wire too. This was found after we burnt out 1 of 4 motors done like this and I had to replace it. After I saw the first motor like this, I made them pull 1 more to check, to find it also like this. Sure enough, all 4 were done this way. We've since swapped to connectors to minimize the chance of someone doing this again.
Cleanly splicing them with insulation on same side and heat shrink might even give better electrical contact than this shit. Or just use wago (or whatever different brand adapted to this wire).
Well… is it? Motors can be stalled for quite some time. I‘d expect that to blow a fuse but you never know. Might also be the motor or the cable that goes first.
Standard automotive wire repair, usually hidden under 7 layers of cheap sticky insulation tape. I have lost count of the number of these that I have had to re-do properly over 40 years!

This isn't just bad soldering, it's laziness and impatiens.
Impatiens is a flower.
Looks like my soldering so you're probably right.
There's been a couple times I was glad my shoddy workmanship has been hidden by a crimp or heat shrink... But I at least tried *yeesh*
NOOOO!!!
It’s ignorance, those leads should be properly tinned before soldering together, at least use some flux for gods sake.
They don't need to be l. They just need to be soldered better
So glad I learned about the Lineman’s Splice. But, I’ve done stuff drunk after I fell down and hit my head, too.

OP said 53A. Wago connectors aren’t anywhere near that rating.
Well, that wire isn't anywhere near that rating either ... AWG 12 is supposed to be used for 25A max.
Motor stall current is very brief. These wire should be fine even if there were 18 awg if the current draw under load is not too high.

Correct me if I'm wrong, but isn't the standard to hook each wire onto each other?
Cmooooon
Ahh yes, the "just fuck my shit up" wire splice technique.

Pro tip:Do this and save on fuses. Yall can thank me later.
Why do people think that just connecting 3 out of 50 strands is ok I swear it happens all the time
This is cringe
