Hello again. Here is the latest Problem with my 86 K5 My blazer seems to want to blow up the Bulbs in the rear end. The bulbs that blow are the two electrode, main light/brake light. The big one. The bulbs are not just burning out, they completely blow up, shattered glass and all, both sides. This is happening fairly frequently now. I check the bulb socket but do not seem to get a spike during the brief period of time that I have a multi-meter to the socket. Any help would be greatly appreciated. Thank you.
