I recently had work done on my fuse block to my starter. It was rusted and not making good contact. The "mechanic" rebuilt the existing block on my 2000 Prostar 205. The stereo had always worked great until then. I now have a very loud hum which gets higher with the rpms. The stereo works fine when the key is in aux but run or start are unbearable. I'm sure it is a grounding issue but could it be something with the fuse block since this is where the power for the stereo is supplied from?
