Smoke. Melted/blown fuse on antispark switch. What happened here?

[Flasher]

Makes me wonder. What’s the switch in Lonestar?

[ZachTetra]

Is that the LunaCycle one basically?

[longhairedboy]

Yeah that looks like it.

[Jayboy]

I can understand how the antispark switch works, but I am rather new to this, and I don’t even know what a loopkey is. Lol.

[Jayboy]

What would abusing it look like exactly?

@Jayboy

I don’t even know what a loopkey is

How to make an XT90 Loop Key

Arguably, the most reliable way to control power to an ESC [pair] is to use an XT90S loopkey. [20190219_024916][20190219_024931] It may not be the prettiest or the shiniest or the most foolproof, but it probably will outlast almost any other way if done correctly, and it’s certainly the cheapest. This does have antispark characteristics if you use the “XT90S” instead of the “XT90” variant of the female connector. You definitely don’t want to use the female XT90. Essentially, you make “a k…

I see. I really like this. I really don’t like the idea of trying to solder on a circuit board. This seems so much simpler. Thanks for sharing this. Are there any drawbacks of this vs. an antispark switch/power button?

[frame]

the only drawback of a loopkey that I can think of would be, needing to find a place to hold the loopkey for physical access and looking pretty at the same time.

[b264]

Yes, what @frame said. The biggest disadvantage of a loopkey is appearance.

Best you can do is epoxy the male end (the one with prongs) into the board somewhere

Loopkey mounting. How do you do it?

So this isn’t for how to properly make a loopkey. But how to mount, hide your loopkey. I want ideas. Would love to see what others have come up with. If you wanna know how to make one

The best looking photos I have seen are when folks mount them up near the trucks somewhere, or in the hole on a drop-through deck that’s been top mounted

[Jayboy]

Would you just have to connect the positive/ground wire ends to some connectors? I’m assuming it comes with the wires and the switch soldered on.

[longhairedboy]

the button has a connector and the last several I got had tinned leads on the inputs and outputs.

[Jayboy]

Well dadgum. It’s a shame it will take over a month to ship. Gonna have to figure out something out between now and then.

[Jayboy]

Okay, so, I tried something that I maybe should not have, and clamped the burnt prong of the fuse onto the circuit board, and it turned on and ran smoothly like nothing was wrong at all. So, theoretically, since nothing in the antispark switch fried, or anything else for that matter, I should be able to just remove the other female connector and solder the fuse straight onto the board, and all is good, right?

I am down to make a loopkey and figure all that out eventually, but did you see my last reply? I think I should just be able to solder a fuse onto my existing antispark switch and I’m gold. The only thing that worries me is the somewhat constant “clean” smell coming from my battery. Lol.

[ryansinatra]

You should not continue to use that burnt antispark unless you are ok with a possible fire.

Also, I know that liion batteries can have a certain smell when stressed and ready to vent so maybe that’s not a good thing as well.

Get a new switch or make a loop key
