Marder free since the first incident

I bought after my first encounter with the raccoon in my new car this product. The raccoon was in the engine compartment, where it has done well damage. Property me then immediately ordered this device and have to say that I no longer had to Marder today (2 months) in the engine compartment. Have made an engine wash prior to installation and then the device is installed in the middle of the engine compartment where the raccoon had also found its way into the engine compartment.
The device has 3 cable, one for the positive battery terminal, one for the negative battery terminal and one for the "terminal 15". The cable for the terminal 15 is the so-called Zündüngsplus, ie when the ignition is switched on, you switch off the Marder Schreck. I have with me the terminal 15 is not found in the engine compartment readily, I have this cable just not connected, so the unit runs continuously, but this is not a problem. In addition, I also had to extend even the other two cables, as I did not come with the original length to the battery, however, was to accomplish with a bit of craftsmanship sent without problems.

The device then sends every 15-second intervals for the beep, which is perceived with an open hood, but listen only at very precise when closed.

As I said I had, since I have installed the device, no more martens in the engine compartment, but the marks on the car itself are not failed. Although annoying but by far not as bad as a defective motor.
