electrical gremlins

[180sx]

Like honestly Fcar gimme a brake for f$ck sake.

So 1 day i was driving heard flick flick, lights flashed and boom ...car runs but no running lights(dash tails front). did my reasearch :

so far: fuses cockpit/under the hood are fine pulled tcu (white box) fried, haha replaced it .....no change what so ever. damn Changed my ecu, cluster, alt fuse (just in case), nothing Checked light bulbs , all good. Ripped my cd deck out ..uno So i just got some glow gages and kept on driving hoping 1 day to find out wtf is going on.

Well gremlin got a brother by than ...last night my battery light and ebrake light start flashing here and there and i hear flickering again. I was hoping my lights are coming back , instead i have constant buzzing flickering coming from above fuse box(some white plug modual unit, not tcu). Its right above fuses box has a bunch of plugs in it . And my battery light went away but ebrake 1 is still flickering and making that white modual/box buzz. I rechecked fusses , tried different ecu etc no go.

Hooked up consult my bat voltage is 12.2 v flat driving or ideling. AAC gage on consult shows me 30 at idle . If i put my car in gear or accelerate AAC gage drops to 14 first and buzzing , flickering goes away!!! AAC gage itself goes to 80 or so at full throtle , an as soon as i let it go drops to 30 , than back to buzzing. If i put it in gear while ideling sometimes it just drops to 14 and stays there buzz freee. And all of sudden will go 30 and start buzzing again.

I am alright at mechanics but electricly blind. Something here is telling me my Alternator Voltage regulator is fried. Any intup is apriciated don't wanna spent 200$ on ALt to find out it wasn't the issue.
