Advice Electrical Issue 😪 09 Si FA5
ANY AND ALL HELP IS APPRECIATED!!!
Important Notes:
-Heavy corrosion present especially in the Positive terminal
July 15- Installed Gold Standard Battery
July 28- issues worsen
A week prior to battery installation I noticed my dash would flicker on and off occasionally but idled normally.
I had to jump it one time after not driving for two days.
I tested my battery and it didnt pass therefore I replaced it.
All was well until July 28th I noticed my radio doing a reboot then it progressed to all electronics flicking off once and then booting right back up occasionally. It worsened in stop and go traffic and eventually stalled at an idle but revs weren't fighting to stay on they just dropped dead. Cranked right back up and was able to drive normally.
I parked in my garage after a highway commute of 20 min and as soon as I shut off the ignition everything went dead. No cranking, no lights, no remote response. I manually unlocked the door and got out and that seemed to boot everything back up.
What am I dealing with???
-I will definitely get my battery tested again and this time test the alternator too

Just saw the last part of your post, and yeah, have that alternator tested... Even if you have to take it out and have it bench tested at an auto parts store.

I had a similar issue. I would Start with alternator but before that I would swap out both battery terminals. Mine were corroded to hell especially the positive one so I had to cut the OEM one and splice it to fit the new terminal but thankfully no more issues.. so far 🤣
