Hey guys/gals, i have an 86' Z NT Manual. I am a first time poster. First off, let me say i have had this car for 23 years. She has been parked for 12 of the last 15 years. Hasn't been plated in about 7 years. Last time i parked her she had some issues, mainly electrical. As it stands i have no interior lights, stereo, head lights or tail lights. Signals, flashers, windows and door locks still work. Fuses have all been checked, therefore my scope of electrical knowledge has been reached lol. Anyone know what this could be? Any help is greatly appreciated
