battery drain, Is my generator bad? Options

[ruby914]

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?

Your testing the alternator with on ohmmeter sounds correct. Diodes will read one way, not the other if they are good. Although this is not a test that proves them good all of the time. They sometimes can break down under load.
Here is what I would do. Charge up the battery , hook everything up like it should be and test the battery voltage when off and when running. Off should be same voltage as battery voltage after charging, on and running should be 13 - 14 volts. If this is good, alternator is probably OK.
Now ( step 1), disconnect the 4 red wires at the + battery terminal and leave overnight. If the battery is good it means you have a drain in your power to the key switch, fuse panel under dash, or relay board. If battery is still bad, ( step 2) disconnect the neg battery post, charge it up and leave overnight. If battery is bad then, you have a bad battery.
If after step 2 the battery is OK, then disconnect the large alternator lead at the starter and insulate it, hook up the battery neg and positive terminals and let it set overnight. If battery now is bad, you have something causing a current draw in the alternator.
Hope this helps get you through this.
