Subaru Problems? Ask a Mechanic for Answers ASAP
Hell, Can I ask how you are confirming the alternator is working? I realize new but to proceed we may need a volt meter in your hands, Let me know, thanks,Randall
Very sorry for the delay, Also, i did not mean "hell" I meant "Hello" , sorry for that, was a typo, I fully understand the problem but only way to help is some testing with volt meter, I had asked if you have one, if not can you get one?
if possible, that would be great, Pls understand you have replaced things to no avail so next step is to do some on car tests, LMK, I will be on/off all day
lets wait a bit. no rush,
1st, put meter on battery terminals, engine running, I need voltage at battery terminals
I was looking at diagrams, ok tomorrow
well we have to keep moving with tests, that is what I was awiting on you for, so,, is car near you? can we do tests? or another time
ok, i am on/off all day tomorrow, some of day on Friday 1/2 day Sat
I know you have on bIg wire hooked to back of the alternator but you have 3-4 smaller ones in a a plug, I need the plug removed, key ON, I need t you to probe the connector and tell me the volts at each wire and if volts, what wire colors have the 12 volts
ok and the big wire at back? its reading? just trying to recap. and do you have guage or battery light?
still need to know if guage on dash or light on dash for charging system. thanks
ok, so you know it is not charging, did we do battery charge volts at the battery?
I am doing all volts test, I need the following: do you have a reading of volts with meter on battery terminals with engine running? also you do not have a white wire in small plug at alternator? if not are there 3 spots in that plug, you only sent 2 wire colors
I am not getting all answers, you may be missing my questions. I asked this:
if not are there 3 spots in that plug, you only sent 2 wire colors

you should have a plug as well as a stud separate from the plug, plug has some wires, the stud has a wire, is this what you have? get with me when you can
I am so sorry we are not communicatiing well. It's my fault.I am trying to ask and explain, It is very important I get voltage readings on ALL wires that go to the alter including the one hooked to the stud, You have said 2 wires, then 3 then 2 so I am a little confused so start over, Please send volts on ALL wires going to the alternator with key on and what wire has what volts. Hope this makes sense, Thanks
honestly? I am at a loss, You have power to every spot you need,Unless an alt is bad, I know of no other reason for not chhaging and.. know you have changed the alt several times so... since you have sent all this, I will opt out, open the post to the other experts, One should be along soon to continue
Hello, maybe I can help. Earlier in your conversation with Randall I see that you said you measured 13 volts with the vehicle running. The minimum you should see is 13.5 volts but really should be 14 volts or higher. If you can put the black contact from the volt meter on the negative battery terminal, and the red contact on the alternator stud and give me a voltage reading with the vehicle running that would take the battery out of the equation and give an accurate reading of what the alternator is putting out. Also, is it possible that the wrong amperage alternator was installed?
As far as I can tell from the diagram there is no computer involved in the charging system. Have you checked the alternator fuses?
Is this a 1990 legacy?
Yes they should be, I believe they are or at least should have been labeled ALT 1 and ALT 2. It'd be best to just check all of the fuses anyway. I doubt it, I've never seen an ignition relay cause that. If you are buying remanufactured alternators it is completely possible that they have all been faulty. If the alternator is not putting out enough voltage then the alternator is really the only possible issue, aside from the fuses.
Ok sounds good
Ok, unfortunately I don't think ill be able to help you so in gonna open it up to other experts
