One of these contacts is connected directly to battery power without going through the ‘thermal circuit breaker’ first. If it touches any grounded metal, it will create a direct short circuit that won’t be broken until the wires melt. (Not just the insulation around the wires – the wires themselves.)
It’s a big risk of fucking up the car’s electrical system much worse than it already is, and could even end up starting a fire that burns the whole car if wires near the melting point of copper touch anything flammable.
Come on, OP. It’s just a little electrical tape. You can do that.
(And a fuse is still a good idea. What if your ‘thermal circuit breaker’ fails – like the previous one did – and gets stuck in the on position? Your car had a fuse on the blinker circuit for a reason. Permanently bypassing it without a replacement is a bad idea.)
I thought I was pretty clear on that: a dead short heats the wiring until the wires melt, the molten metal catches some plastic part on fire, the whole car burns down. For total worst case scenario, let’s say this happens on the highway during the middle of a family road trip, several states away from home.
This literally cannot touch any ground points. It’s impossible. I made damn sure of that.
You know what could make really sure of that? A $1 roll of electrical tape.
OP, please add an inline fuse to that! And cover those exposed contacts with some electrical tape.
There are no exposed contacts. I was very cautious about that.
It’s basically a fuse to flasher adapter cable, custom made.
Works perfectly 👍
Cover this
Don’t need to. Even if the wires somehow short out, then that’s just back to the original problem, flashers stuck on…
It works and flashes fine, and the electrodes will never touch each other.
Touching each other is not the problem, if either of those touch any part of the body you will have a ground fault failure.
It’s literally a thermal circuit breaker. It works perfectly in circuit.

And even if it somehow does fail someday, what’s the worst that’s gonna happen?
Back to the original problem, blinkers don’t flash, just stuck on.
This fix works fine though.

Good point.
