So I’m currently working on my first build and it’s coming along pretty well, until I tried building my anti spark key loop. I have two lipos connected in series with a series adapter going into another series switch which connects the anti spark key and the vesc. When I tried plugging in the key switch for the first time, there was a huge spark that basically fried one of my series adapters. Thankfully the batteries and vesc still work. So is there something I did wrong? And can someone tell me some specifics about how to build an anti-spark key loop? Should I just give up and buy a vedder switch instead?
This was the first page I went to when researching. Everyone says that it’s just a simple series adapter with a key switch that closes the circuit. I’m pretty sure that’s what I did, unless I missed something?
Show us your connections irl or on diagram. I had a situation similar to that of your’s but that’s when I used 13s. Not sure how much difference it would make depending on your setup but voltage could definitely be a factor.
Could you have gotten the polarity wrong?
Just to make it clear you are NOT connecting + and -. You are taking for example the red/+ line between the battery and the vesc and breaking that with an XT90 Antispark connector.
I’m running on two 4S in series so basically in 8S, so not as much voltage as you’re running lol. I’ll have pictures up in a moment so I could show you what I did.
How huge? Show us a photo of the burn mark. Some sparking may be normal under some circumstances, but unless I see the crater in the metal I can’t say.
A photo of the wiring and adaptors and loop key would help as well
Oh yeah I made this in a hurry, so it wasn’t really that good. But I did make sure that the positives were only connected with the positives, same with the negative wires. Sorry for the confusion.
It was pretty huge. Almost like a small ball of light lol. I’m not at home right now so I can’t show you some pictures, but the burn marks weren’t that bad. I just saw some black marks inside of the connectors. But it was enough to short out the series connector I made.
