Full story:
I’ve been working on my EVO 10s5p AT wheel build for a long time, every single thing was programmed, mounted, secured and ready to go. I put everything in position but didn’t actually turn the screws, I wanted to test it one last time.
Just my luck, the anti-spark switch started acting up. The thing seemed to be stuck in the off position, I had to hold the button down to keep the ESC on. So I undid everything and found that if I flexed the switch I could get it to stay on. I had tried many different iterations of wiring set ups and all of that probably was too much for that thin wire on those little terminals. I re-soldered the connections (pic is my peasant tier soldering job) and now the switch is stuck in the on position. Did I break the switch?
Also that one empty connection you see in between black and blue was empty before I redid this, that’s how Jason from BKB had it set up and it worked until today.
I am not sure where to start. That switch needs insulating asap. Is it connected directly to an esc of chinese origin? Or an actual anti spark component?
@Dareno That button is connected to a buildkit boards antispark switch, which is then connected to an esc of chinese origin. I definitely plan to insulate the connections but as it stands I’m probably just gonna cut that button off and try a new button.
@Halbj613
The switch is in between the BMS and the ESC, I’m hoping it’s just the button that’s messed up that’s forcing the switch to stay in the on position. Are you talking about a button like this?
If those are your solder joints… No offense in any way… but you’ve probably got much more wrong/needing help in the entire build than just the anti spark failing.
You should to over the how to solder thread and also post pics of the rest of the build in the noob questions (or here/make your own build thread) so people can give advise. Just don’t want your build to die in you, that always leads to frustration
Ok thank you so much for saving me from spinning my wheels on a new button. To everyone worried about my soldering, do not fear, I am just going to pay an RC shop to do the soldering on the final product and will save my learning for a project that my life won’t depend on.
Shoot I don’t think I’ll be getting my hands on one of those for awhile with Corona virus preventing cargo from getting into the US from China… I’m going to abandon the switch idea and see if I can get a loop key made by the RC shop I go to.
My local RC shop does a soldering service too but to be honest its a good skill to learn and making a loopkey is a great place to start.
Have a read and then have a go at it.
For a while there I was incorporating a loopkey into the anti spark switch as an isolator and it also comes in handy when the switch inevitably fails as they predominantly fail open as in permanently on.
One thing to remember with any kind of new learn is to get the right tools. Get a decent iron and a set of “helping hands”.
Hey Dareno, even though I had the RC shop build my loop key I wanted to take your advice and learn how to solder. I’m starting with just joining scrap wires together. Does this look serviceable, or at least like I’m getting the idea?
Its good but there is no need to strip so much cable as you get more proficient. Soldering is as much about when as how. Once you have the heat generated the solder flows perfectly and that heat depends on the size of your cable and the size of the tip you use which is why its always a good idea to have a solder station capable of heat adjustments and changeable tips but as a first go then that is a good strong joint. At the end of the day that is really all that you are looking for.
