Advanced Battery Charging System

[stockguru]

So after reading all the posts about battery issues, I decided to purchase the Advanced Battery Charging System from my Stealer.

So either this thing isn't working properly or I'm just not smart enough to figure it out.

Both my red light and green light flashes. Which I guess means that my battery is over 80% charged and the battery is not connected properly?

does anyone use this thing and have any tips? I can't seem to get the red light to stay on and show "charging". I'm connecting the red (positive) to the auxiliary positive terminal under the hood and the negative (black) to the post not too far from it.
