oh yeah, the alty strap doesn't seems that tight... could it affect how it works?

what strap?

It could be your lack of keeping up with maintenance and the motor's idle dropping. Just a few hundred RPM drop by the motor can cause this.

RU kidding??? You think there is R&D in your shitty hyundai dude?

Sounds to me like your factory alt is saying goodbye, 90 amp factory hyundai alt isnt meant to have to charge 2 batteries
