I just did the 3g install on my 90 and followed the corrals direction to a t. And the battery lite comes on from the little white wire that was left off so Iput it on. So now all wires are on alt and none left out.

Then I cut the blackw/orange stripe wire that was on there and ran a 4 gauge straight to the battery. Works fine.!!:D :D :(

Now, in the mornings the battery dies overnight. The firts night without the 4 guage it died really bad. Night after not as bad.

I just plugged the little prong in from the stock alt to the new and cut the wires from the big/wider prong.

I ran my 4gauge to the starter solenoid. That way it's hidden and not clumping wires on my battery. Not sure if that makes a difference.

My first thought it the alt or the 4gauge is grounding to metal somewhere and slowly draining the battery. That's all i can think of reallyt
