The easiest way to check any alternator in a car is to have the vehicle running and use a VOLT meter to read across that battery terminals. The voltage should be in the range of 13.4 volts to 14.5 volts..no lower, no higher. If either low voltage or high voltage exist, that alternator is probably defective.
Remove the wiring harness from your 1990 Subaru alternator. Remove the alternator belt. Remove the alternator retaining bolts. Reverse the process to install your new alternator.
Check the grounds on headlights
