I purchased an anti-spark from anti-spark heaven and a power switch a little while ago for my upcoming Icarus build.
The Problem: when I wire everything together my multi-meter reads full power regardless of the button being depressed or not and the LED glows no matter what.
Configurations I’ve tried (From Anti-Spark to Switch):
Option 1:
NO -> NO
C -> C
NC -> NC
LED+ -> LED+
LED- -> LED-
Option 2 per suggestions I’ve seen on the forum:
NO -> NO
C -> C
No Connection between NC terminals
LED+ -> LED+
LED- -> LED-
Any suggestions?

Your antispark switch could be broken and stuck in the on position.
This is very typical of antispark switches.

I have the same problem.
I’ve now tested it with a lower voltage battery. 14V to be exact. Works perfectly fine.
At 41V - 50V there’s a spark when I connect the switch to the battery and the circuit is stuck closed.
I’ve tested both MOSFETs and they work as intended.
I’m thinking the problem could be the spark upon connection or maybe my BMS.
Any help would be useful.
Total honesty here…mine was soldered backwards. One of the labels for the polarity was written wrong on the anti-spark itself and I didn’t see it at first. Upon reversing the direction of the anti-spark it worked as intended.
As an example, here’s how it should be wired: Battery --> (IN) Anti-Spark (Out) --> Focbox. I had it this way…
Battery --> (OUT) Anti-Spark (IN) --> Focbox
After reversing the flow by re-soldering the correct direction for the connections mine worked fine.

Thanks for your reply!
I have mine wired the right way.
Guess I have to keep looking for a solution.
Okay problem is solved!
Actually there never was a problem. Just a lack of patience on my end.
After pushing the button to turn off the board I have to wait about 30 seconds for my ESCs to power down.
Add another 30 seconds and the LED has faded aswell.
Hope this helps someone in the same situation.

Glad you got it sorted! I wondered the same thing when I first got mine working. Have to give the caps time to drain I suppose.
Is it better for high amps?
Never actually done that before.
