Bruce Collinson Posted October 4, 2019 Share Posted October 4, 2019 All, On an XT-90 anti-spark, is the male side the one with the green resistor? Whichever, which one goes to battery? Before anyone's tempted to allude to my difficulties in gender identification, both sides are shielded, unlike my usual Dean's. BTC Quote Link to comment Share on other sites More sharing options...
flight1 Posted October 4, 2019 Share Posted October 4, 2019 it shouldn't make to much odds but the connector that is least likely to be able to be shorted should go on battery side, so that should be female plug ie female contacts that are shouded by the yellow housing.

John Lee Posted October 4, 2019 Share Posted October 4, 2019 No. The pack of XT-90's I bought from Hobbyking had the resistor in the female side, which is the battery side. It's the battery side for two reasons, 1) it's less likely to short out by a stray object and 2) that's what's pre-fitted to all so equipped batteries I have come across. Unfortunately that means it's no good for fitting to the model/ESC side, which is what I wanted to do as it's far easier than than removing & replacing the connectors on all my batteries. If anyone knows a source of anti-spark XT-90 male plugs I'd be interested. Quote Link to comment Share on other sites More sharing options...
Don Fry Posted October 4, 2019 Share Posted October 4, 2019 I got some from Steve Webbs, probably 18 months ago. Not cheap. Quote Link to comment Share on other sites More sharing options...

John Lee Posted October 4, 2019 Share Posted October 4, 2019 Could you post a link please Don? I've just tried multiple searches on Steve Webb's site & can't find them. Quote Link to comment Share on other sites More sharing options...
Bruce Collinson Posted October 4, 2019 Author Share Posted October 4, 2019 Thanks so far. Both sides of XTs are shielded, hence my OP. John, George Worley at 4Max has them, genuine Amass. BTC Quote Link to comment Share on other sites More sharing options...
John Lee Posted October 4, 2019 Share Posted October 4, 2019 Thanks, I've just found them on Servoshop Link and 4Max Link but in both cases the resistor is in the female, battery, side. (Female in this case = the gold connectors, not the plastic shielding). Quote Link to comment Share on other sites More sharing options...

John Lee Posted October 4, 2019 Share Posted October 4, 2019 Same issue - they are for the battery side. Quote Link to comment Share on other sites More sharing options...
flight1 Posted October 4, 2019 Share Posted October 4, 2019 yes i am right always confusion with male and female connectors these days As for electrical connections you should always talk about the electrical connections and not the housing that surrounds it. as for shorting out the resister won't prevent this just slow the amount of current flow on contact so it works just as well battery side or the other, basic electrical principles here.

Bruce Collinson Posted October 7, 2019 Author Share Posted October 7, 2019 Embracing the foregoing I duly soldered the ESC to the male side and the battery to the female side. The relatively slim ESC leads have a significantly deeper cavity to solder into, and vice versa with the battery leads which are pretty thick but nothing like as well anchored. Seems quite counter-intuitive. BTC Quote Link to comment Share on other sites More sharing options...
Andy48 Posted October 7, 2019 Share Posted October 7, 2019 I always use a shorting plug on the side of the model. For larger models I have a small push-to-make switch with a 10k resistor soldered across the shorting plug terminals. Before inserting the shorting plug I press this for a few seconds to charge the capacitors in the ESC. Simple and cheap. Quote Link to comment Share on other sites More sharing options...
