My dad did a fairly hokey stereo install on my 83 Monte and after that I started having the odd electrical gremlin. Stereo would randomly shut off and on, headlights wouldn't turn on unless I put the switch in and pulled it out again. Today I started my car up, it was cold so was idling a bit rough and during the idle the radio kept shutting on and off, once the idle stabilized the radio was working fine until I hit the gas and which point it promptly lost power and now I no longer have headlights, radio, or my key buzzer. I need to take my car to work tomorrow in the dark so I need this fixed ASAP, any help would be appreciated as my dad is none and I really have no one else I can go to in person. All my fuses seem good and ive replaced a few of them including the one under the dash. I know **** all about wiring but everything appears ok.
