Yes, I was driving the other day in the rain. I had my wipers, heater, lights and stereo going. I wasn't paying attention to my battery meter, until my stereo kicked off and the needle was in the red. When I finally arrived home the battery had enough juice to start the car one more time, then I had to hook up the battery charger. I was so glad I had my 3G waiting at the house for the install.
Speaking of, I do have the 3g installed (see attached photo). I ran a 4 AWG wire from the positive post on the alternator to a 200A fuse then to the positive side of the starter solenoide. Then I attached the green wire from the original harness to the provided green wire that came with the alternator, which I also did with the yellow wire (See original photo). From the old second harness that seem to be the output wires (two thick black and orange wires and one white). I just disconnected the wires and left them hanging around just in case.
Now, everything seemed fine, but the needle keeps moving slightly up and down, very suddle, is that normal? Also when I turn on something electrical, like the heater blower, it drops for a half a second then bumps back up to its original spot, also the lights dim for a slight second when I do that as well. Does this seem normal to everyone? Should I connect the black and orange wires to the battery post on the alternator?
Thanks for the help guys!
P.S. I have a few more pics of the install if anyone is interested.
