1991 240 with stock radio, last week #1 fuse blew shutting off radio. Replaced #1 fuse and radio worked fine while sitting in driveway. Drove car for about 3 minutes, blew the horn on the way past son's houses, radio went dead because #1 fuse blew again. Checked fuse holder, cleaned, replaced fuse and checked wiring connectors at back of radio and re-racked radio. Worked fine sitting in driveway, three minute of driving got a "bulb failure warning light". Just as I have done for the last 20 years I tapped the brake pedal to clear the "bulb fail" light. The light "bulb fail light" went out and so did the radio because fuse #1 blew. Any thoughts on this strange electrical happening??
