08 Civic SI electrical problems?
After work today i started my car and let it warm up for a good 10 minutes. when i went out to leave i noticed all my electronics were reset. i didnt think anything of it thinking my coworkers were playing a prank. but as i drove out my radio kept going out and coming back on. this had happened once before but it hasnt happened for a while.
as i got on the highway it was fine. and stayed fine until i hit traffic. then all my electronics blinked. then once my car died out for like 1 seconds and then jolt back on and my tires screeched cuz i had my foot on the gas pretty hard.
a little later down the road i turned my lights on and all my electronics including all the dash lights flashed on and off as if i was starting my car but the car didnt die or anytthing.
finally when i got home i shut off my car and as soon as i didnt i noticed all my electronics died. no lights worked. so i put my key back in the ignition and tried to start it and its completely dead. no click no nothing. i checked the battery cables and they are tight...
i have no idea where to start. i thought it might be the alternator but the car would at least turn over if it had gone. plus i have had similar problems before but they went away.
any ideas where to start?

Check charging system. Alternator is a fine place to start. If you suspect elsewhere in the circuit, let me know what you need as far as ETM info.

^^^ agree also check ur battery might be dead if you havent replaced it in 4 years can be a dead batt. Also check any lose grounds. Did u cut any wires?

Charge the battery and start the car, then check the voltage with the engine running. If the alternator is charging properly, you should be getting 13.8-14.4V. If you're just getting battery voltage (12.0-13.0V), something is wrong with the alternator circuit or the alternator itself.
