alternator problem 95 subaru legacy

my cars electrical system just started acting up, the gauges went dead, abs light came on, my alpine deck automaticly shut off. everything would come back on if I held it to about 3000 rpms. I just need some reassurance that it is my alternator.

check the battery/ connections first

Did the connections already, no change

also there is a ground on the intake tends to get rusted up pretty good. try that. when in doubt if it’s an alternator start the car and with it idling pull off a battery cable. if it dies 97% chance it’s the alternator.

replaced it last night and it was the alternator, fixed and running
