Draining Storage Units without power-usage?

Hey guys, I already use IC2 for a while now, but I never had such a problem: Although there's no usage for any energy (no machines lined up, etc.), my BatBox, MFE and MFSU lose energy. I don't know where that drain is coming from, I hope anybody of you is able to help me.

Yours sincerely

I tried in my testworld, hooked a geothermal up to a MFSU. The MFSU is hooked up to nothing else, but it's still draining. Also, I found out, that the internal storage of my generators (geothermal as well as normal generator) won't fill up either. I really hope, somebody got an idea ...

Edit: Maybe, it'll help you to know that I downloaded IC2 from the forums and placed it as an additional mod in the Ampz Modpack from the FTB Launcher. There are, so far, no further problems.

Edit2: I'm currently working around the problem by using the Advanced Battery Box provided by Electric Expansion with the compatibility module, but I doubt that this will help for long, so I'd be grateful for any help

There aren't any machines on the system. All I placed down was the MFSU and a geothermal generator, and the MFSU doesn't even reach 500 EU stored, because it drains immediately. And I don't have GT installed

[MC 1.5.2] Open Beta v1.117

Yeah, I guess so. That's the version I'm using

Thanks, at least I know by know what's going on. I guess, I'll have to wait for an update

You can downgrade IC² to 1.116-374lf

Well, that would actually help me a lot. Thanks very much!

Remove Mekanism, it's broken. See http://bt.industrial-craft.net/view.php?id=455 for details.

That worked, thanks a lot! We'll test that solution on our server as well. Thanks for that solution.
