The WRX914 has a battery drain. Pulled all fuses, relays, grounds. No change.
I ended up at the generator? I pulled the two big white wires off (coming from the battery) and removed the plug with two small wires. The pole that the two big wires went to has continuity to ground. Is this telling me that the $200 generator is bad? |

I just took readings on mine and I am reading in the megohms with the negative disconnected and everything else hooked up.
Since you are saying you have a lot of the WRX electrics installed, then that is where I would look for the drain on the battery. Sorry I can't help there, no Subaru experience. How are the Subie electrics getting power? Isolate the power to them and take new readings. Lower ohms to ground readings with things off = more current when sitting overnight. In a perfect electrical/electronic system that would be 0 amps. Theoretically possible, but not practical. You will always have a very small current. By the way, do you get a small spark when hooking up the battery? That is a good indication that you have something drawing current. Tom |

Slow to update because my Modem is acting up like my car was. The car sat for days with every thing hooked up but a door is off and the door ajar light has been on all that time. Car started with out a problem yesterday. I look forward to get this body work on the door completed and start driving again. I am hoping it fixed its self because I didn't do anything. And hope I am not speaking too soon. Now, I wish my modem and lawnmower would follow the cars example. |

Since things don't fix themselves, you should hope that there was a misconnection or a bad connection that you corrected in all the tests etc you did. Otherwise, the problem will return (and, in my past experience, with a vengeance) |
