Have a 86 Subaru GL Fuel Injection and I am looking for what he alternator should run at... I had it checked and volts were alright but my amps is at about 2. I was planning on replacing it anyway and was just curios what my amps should be at the worker who tested it said it should be at 4+ but he didnt look to informed or the subject.

Thanks in Advance if you know the answer!

uhhh... the 2 and the 4+ seem like some scaled number... stock alts run about 60 amps, and like the xt6 runs about 90... you need a real number... is it doing anything else strange? When running check volts at the battery... should be abouts 14 volts or so.

Just put a new alternator and and it tested the same... DAMN YOU ADVANCE AUTO PARTS... But it did check out ok at the subaru specialist. So we tested the machine at advance auto parts on another car to see if it was working well... it was also reading the amps low anyway So now i have a newer alternator that really wasnt needed but it seems to be running a little better so maybe the 40 bucks to replace it and put a new one in isnt that bad. Thank for the help and yes 60 amps is around what it should be max.

You do realize that altenators dont start to put out full power till 1200-1500 rpm

 

nipper

Ya I was testing them at 2000+ RPMs and comparing them to the originall tests of the product my new one works great while my other one had its problems

PS the 4+ ya the guy who did it wast not that smart... I noticed on the machine it even said what it should of been... right underneath him lol.
