Battery light

[Jcg_3v94]

So my battery light came on as well as my check charging system notification, had battery and alternator tested and both passed, i was driving back home when i noticed my battery gauge jump up super high while i was accelerating from 2nd to 3rd gear. Checked and cleaned terminals and wiring. Any help? Thank you.

Bad alternator, especially if factory unit.

In that case your alternator should have a clutchless pulley. If it doesn't, you'll need to convert it.
If that doesn't resolve the problem, I'd say the voltage regulator has gone south.
