86TwinTurbo

Hey I have a quick problem...i turned on my car and i heard a pop noise and looked at my voltmeter on the dash and it was dead zero..also there was a fire like smell... stayed this way for a few days and then it started reading normal voltage and then it died on me again today and has been that way the whole day...i was thinking i blew a fuse but it was working if it did..whatelse could it be?
