Hello all, recently my radar detector stopped working so I went to the web and found the correct wiring diagram. 
Looking at the diagram I saw that there was a inline fuse. Ok I thought, that should be an easy fix. Well I was wrong for a very strange reason. There was a capacitor in the circuit instead of a fuse. I've modified the original diagram to show the current circuit here.
So, since I know very little about electronics, I thought it would be prudent of me to see if I could find out why this was done before I ripped the capacitor out and put the fuse back in. Can anyone out there explain why this was done?
Thanks, all replies are appreciated.
