potter2010 posted a topic in 1990 to Present Legacy, Impreza, Outback, Forester, Baja, WRX&WrxSTI, SVXI have a 2001 Subaru Legacy L Wagon with an infuriating battery issue. I'm sure more people will immediately say search the board there are lots of other topics relating to this but rest assured I have spent the day searching the board, as well as Google, reading and trying everything I'm able to. However, if I've missed something please feel free to post the link. Here's the background: purchased in the spring of this year with no problems. Since it started to get cold the last couple weeks it has had trouble starting and finally would not start. A couple of times I had gotten it started by shifting into neutral but this may have been a coincidence as it doesn't work anymore and doesn't jive with everything since then. Lights, dash, etc would turn on and were bright but no crank, no start, no click, no nothing. Had the battery tested and it was dead. After a charge it had 10% health and was quickly losing its charge. Bought a brand new battery and the car started instantly and worked great. Within two days I was in the same situation: lights bright but no start. Got the new battery checked and the health was 100% and held a charge. Car started great. Battery died again within two days. Obviously something is draining the battery. When the car is off the drain on the battery is only 0.02 amps, so well within the good range from what I understand. The alternator is kicking out nearly 15v when the car is started and the battery was near 13v when the car was off, following a full charge to the battery. I used the diode check function on my multimetre to check the indirectly test the diodes on the alternator. Long shot I know but I'm grasping at straws. With the main wire to the alternator disconnected, touched my one probe to the bolt where the wire connects and the other touching the casing. In one direction I got an infinite reading and the one direction I got 0.455. I repeated this a few times and got the some readings. I scratched into the metal for both to get a good reading. I'm not sure what the diodes in the alternator are rated for but I thought the readings might be low and if one or more are damaged they could possibly be draining the battery when the car is off even if the alternator is charging while the car is running. I'm read but at wit's end trying to figuire out what is draining the battery. Any help would be great!
I did some searching, but I didn't come up with much and electrical issues are my biggest weakness. So if I'm asking dumb questions, please enlighten me with your ingenuity. The car: 1984 Brat with a replaced EA81. When the engine was replaced, some "extras" were removed and I definitely have some wires to nowhere. The issue: Recently, when I turn the key to start the car, 1 of 2 things happen. It either: 1. Starts right up. OR 2. The dash lights up, the battery gauge needle hits about 8-10V and the starter doesn't turn. If it starts and I drive it there are no issues. If I roll start it, jump it with the 50 amp setting on my batter charger, or jump it from another vehicle there are no issues running it and driving it. Once it is running the needle sits just above 12V and everything is great. I got my battery tested. It is supposedly fine. It seems that no matter what, if I drive the car then shut it off, it always starts back up if I try within a few minutes. The questions: Is my starting circuit grounding somewhere intermittently and killing my battery? I'm assuming an intermittent short to ground because sometimes the battery is fine and other times it gets drained very quickly. What should I look for? Edit: I'm not sure if it matters, but the car had been mostly sitting for a year while I worked on it off and on to finish the lift and do some rust repairs to pass inspection. I just started driving it again last week and that is when the issue started. Edited again for grammar.
I have a 95 Subaru Legacy, Starting to feel like my parents gave me a money pit. But I'm hoping to come out with a Money pit worth having. Did the wheel bearing myself, Car doesn't have reverse (Got transmission, going to get it swapped) The transmission sets me a little over 1000 for used transmission and trans swap. Just recently I got a battery light, car died while driving. I took the alternator out and the battery to the parts store, they tested both of them and determined my alternator was good, but the battery was bad. I bought a $125 battery for it, and here I am two days later battery light on earlier today and car dies while driving tonight. Some how "my alternator is good" but my battery is not getting charged. Anyone have this problem, Where do I start?? Thanks for all the help here ya'll. I got some great info when I originally posted about my transmission which led me to finding a decent deal on a used transmission. Travis-
