Help! Z-Atty U voltage drop

[cd.rno]

I have a z-atty u that I picked up here on the classifieds. It shows serious voltage drop when the positive & ground screws are connected, even with just a single piece of wire. Without the wire the voltage is fine.

I have cleaned it thoroughly several times with isopropyl and lightly sanded the contact points.

I'm hoping that someone here can help. Thanks!

Edit: I guess in the thumbnails it's difficult (impossible) to see but without the wire it reads at 4v and with a single piece of wire connecting it reads at 2v.

I came on here looking for the same information... I just recently grabbed a z-atty-universal and am experiencing a HUGE voltage drop under load.

Have you figured anything out with this cd.rno?

What kind of wire are you using? resistance wire?

It is a known issue. It is mostly due to that spring inside the atty housing. From what I understand this is normal and was intended to do this. Whether you clean it or not, the voltage drop will still be there. Only thing you can do is to modify the center spring to some type of brass piece or thicker spring.

Sorry, I had pretty much given up on this thread after not receiving responses for a while and haven't visited the forum for a little bit.

@bigleft, No real resolution yet.

@varivapr, Yes, 28ga A-1 Kanthal from Temco.

@Rymarski, Thanks. I've read that entire thread and was hoping to avoid heavy modding of the atty. I also found it odd that the drop occurred only when the posts were wired up, which made me question the fact that the spring was actually the issue. It sounds like replacing the spring with a brass post is my next step.

I appreciate the responses!

I ended up chopping and duct taping together (figuratively speaking of course), my own center pin... problem solved. Ashame I had to modify such a pricey atty to make it work properly. I think I'll mark the zen line of products off my list of future purchases.
