Hello folks,


We've tried using contact lube - no luck.


If it's an environmental issue, try flooding the connector with the
same gel (?) that telco's use for their wire joins. Or try vaseline.

Agreed, silicone grease fill the ATX female and fill the male side as
well, this will be messy but should stop the corrsion.

On next design, make sure the crimped connections are CORRECT or use
screw terminals, preferably. ITC0008 pincushion thick 3 wire plugs
had mis-match gauge crimp that it is just enough to develop resistance
over time or tin pins/contacts corroding.
Soldering wires directly to PCB was the solution on ITC008.
