Hmmmm, the blown fuse could always be just a coincidence... but maybe not. How about if you have a loose ground on that circuit that is causing the radio/light to go in and out some times... and then that loose ground wire touches something it shouldn't and shorts out, blowing the fuse? Just an idea. mark On Wed, 19 Apr 2000 19:42:58 -0600, "Christopher A. Nowell" <c_a_nowellnopsamail.com> wrote: >I put the JVC stereo in myself a while back and have had no problems with >it.
