I picked up a used alternator from a 98 Forester to use in my 99 Forester - only had 30 K on it. I had it computer tested at a local auto shop -- passed with flying colors with 98 info. entered into the machine. When they punched in the criteria for a 99 Forester, however, the alternator was determined to be bad.

 

Connections and terminals are identical between the one in my 99 Forester and the 98 alternator, but part and model numbers differ. I decided to buy this used one because 1stsubaruparts.com has one listing for the "98-99" alternator(s). The local parts store, however, lists two different rebuilt units for the years mentioned.

 

Questions:

Does anyone know the amperage of the 98 alternator (75 amps for 99)? What risks are involved in the swap?

I don't see any problem with using it. I would trust 1stsubaruparts.com over a parts store computer any day.

Thanks, Shawn.

 

Anyone else with any thoughts or info. would be greatly appreciated.
