molex blues

First of all I think the seventh circle products are awesome. I've built the A12 and the N72 now and I love the A12... use it on lots of stuff. The N72 I just built last night, so I haven't really gotten to live with it for long, but I did put it through its paces a bit and really liked what I heard!

But am I the only one that has trouble with those Molex power supply connectors? Both times I've built them, populating the board was the easy part. Then I go to apply power to the damn thing and I always screw up at least one Molex pin. I bought some extras last time which came in handy this time. But I even bought a special Molex crimping tool, and I'm not a dumb guy, but they always end up coming out just a little cockeyed so that they don't "seat" properly in the plastic housing. Then when I plug it in, half of them pop out and I have to push 'em back in. I really wonder if there isn't somethng I'm doing wrong.

I also had a bit of trouble getting everything to poke out of its intended hole on the chassis. :D And for some reason, two of the screws that hold the top of the chassis on, the heads of them sheared right off when I was unscrewing them. And I was carefully using a hand-operated screwdriver, no power tools. Maybe I'm just unlucky!

But I am two-for-two in getting the things to power up and work properly the first time, so that's good! It's just the "finishing touches" that I have a hard time with! :?

It sounds like you're mashing the crimp connectors too hard. The inner tabs that grip the wire need a lot of force, but the outer tabs that secure the insulation don't. The connectors fit into a slot which forces the locking tabs to latch the small windows at the back of the housing. If they're inserted properly the only way to get them out is to depress the locking tab while pulling. They should never slide out when mated to the header. If it's too much bother, you might want to just buy a WH01KA.

thanks for your help!

Next kit I buy I'll probably just get the harness as well.
