The two colored wire is connected to the amp board properly, the same
goes for the single colored one. This happens also with a cat-5 cable
that is not screened, I was using that before I got screened cable. The
sheld it self is not connected to anything, since I can't connect it to
the ground, at least I don't know how to connect it to the ground. Since
I don't see any connection for it. I know that the problem is not in the
amp board. There are capacitors inside the geophone, I think that thease
are capacitors. I can ground the shield of the cat-5 cable. If I get
some instructions on how to do it. I can also replace the capacitors if
I know what to buy and how to replace them. I know about good electronic
store in Iceland that sells this type of items.

This spike problem has been getting worse since I got the geophone, it
was not there in the early start. In the past 2 months it has been
getting really bad.
