2G Battery and Yellow Oil light flicker.

[Flippy]

Hey Guys.

I have a problem with my 2g.

Last weekend while driving, after i installed an 165 A Alternator.
My Battery and the yellow Oil light came on at the same time.
Sometimes they are off, but most time they are on. rarely the ABS light goes on too.

I noticed that the Alterstart 165A Alternator got really hot. (I installed a second + and ground wire, like the instructions said)

after this, I removed the Alternator and installed an Original OEM Alternator again, but the issue stays
Do someone have an idea what could be wrong with my car :/

(the car runs on 272 Kelfords, so the rough idle is normal)

Check your alternator fuse, the big 80 amp one and check the alternator for charging.

What's the voltage at the battery, and alternator?

Same exact issue I had when my alternator regulator was going out eventually my interior and then followed my my exterior lights started flickering..galant alt fixed my issue but since you've tried two alternators makes me consider wiring between the circuit and the fuse link like @1990TSIAWDTALON mentioned.
Thank you for your time, Jason Penny

coming back from my car right now.
checked the Fuse, -> okay.
I have 14.5 Volts at the Alternator and 14.2 Volts at the Battery.

just noticed that my headlights bulbs are dead and my interior light (sometimes) is flickering too

it sounds like i have exactly the same issue like JPenny had. but i tested two alternators. :/
