ikarma70 Posted November 6, 2016 Share Posted November 6, 2016 Hey guys, this one has me scratching my head! My WE 7.4v mini stick was showing up on my IMAX b6 charger as low voltage and connection break warnings so I thought I would replace the deans plug. Upon stripping the outer insulation back a touch I noticed the silver plated wire was dull and showed signs of a green copper oxidising so I cut the silicon insulation back and yet more oxidisation. I pulled the remaining insulation off and the whole live wire was all the same but the negative wire is still bright and shiny and there is no damp in my battery bag as I use silica packs. Any idea's please? Many thanks Andy Link to comment Share on other sites More sharing options...
Aaronrichardson Posted November 6, 2016 Share Posted November 6, 2016 It could just be reaction between the insulation and the copper wire. Check to see if the insulation looks faded (due to heat). You could also do a resistance check on the wire... Also check your battery is not leaking at the terminals, only ever seen this once not on airsoft on something completely different but yeah still worth checking that over...

Hangtight Posted November 7, 2016 Share Posted November 7, 2016 It's a common problem on vehicles where the battery is left connected over winter. I'm not sure of the mechanics of it, but on my bike it's been a complete pain in the rear until I started disconnecting the battery when not in use. Not sure how you prevent it if you're already taking the battery out when it's not being used. Link to comment Share on other sites More sharing options...
ikarma70 Posted November 8, 2016 Author Share Posted November 8, 2016 Well here's the odd thing, it happened within a few days unless it's a bad batch of silver plated wire? Link to comment Share on other sites More sharing options...
