Battery/generator warning

Hello guys,

I had to take my generator out to install daylight relays, and when I had it out, I changed the voltage regulator to a new one.
After this all my problems started.

After a couple of starts I got a battery/generator warning.
I noticed that I got it if I just put my ignition in acc on position and it came on just after my oil check, and if I started it, it would stay on.
If I just started the car immediately, then it wouldn't come on.

I had to go away for 5 days and when I came back my car was out of power.

So I figured it maybe was a bad voltage regulator and bought a new on. I installed it yesterday. And charged the battery up to full, checked the battery overnight without putting it in the car and it hold the power very good. Charged up to around 12.89v and a drop overnight for like 0.03-5v - which I think sounds acceptable.

The same error comes on if I just put the ignition to acc on after 10 seconds.
I had no errors before I took the alternator out the first time.
I'm on work this evening and tomorrow morning I will find out how much the voltage drop is overnight. I measured it at 12.47v.

Does anyone have ANY clue of why the error is coming?

/Kim
