Subaru ej22 not charging the batery
Posted: 03 Sep 2009, 12:40
hey all how's it going, I posted this on VWKD so sorry if your reading it twice but...
bit stumped here. I was driving a long on Friday and I ran out of electricity! so I think my alternator is dead as my battery is only 1 month old, get specked home, Saturday morning phone the scrap yards they don't have a 2.2 legacy but they do have a 2.5 quad cam, (hanford hall if anyone is interested in it, didn't look at the engine much as all I wanted was the alternator) take my alternator along to check its the same and it is, so £40 done, take it home fit it, but still no luck, the alternator doesn't kick out a charge! Yesterday morning I take both alternators to a automotive electrical engineers and they bench test them, say both work but my old one the warning light doesn't work anymore.... Hmmm fit the 'new' one again double check everything and clean all my earths. Still no charging! Spoke to a friend of mine and he asked about my battery light on the dash board. It doesn't come on ever, put the key in turn it the light doesn't come on, oil light does but the battery one doesn't. Start her up and the light doesn't come on. He tells me to check the light bulb so I swap the battery and oil bulbs around and they both work. So am I right in saying the alternator needs to be excited to start charging, this is new to me so bear with me, and if so could it be a relay sticking/no working? or some wiring come undone somewhere?
Cheers,
