Alternator Wire? Got No Idea!

[bygrave316]

Hey guys installing a second battery in my car have got a Battery isolator for the batteries but got no idea where to find the alternator wire is going to the main battery.

Need to find that disconnect it and connect it to the isolator then connect the to battery + to the 1 and 2 posts of the isolat...

So can someone please tell me where the alternator wire is.

Its got to run to the battery somehow doesnt it?

Anyone got any idea about this?

Ok... I did some really heavy and deep searching on the net about this..... all i could find was a really small mention about an aqua (light green) wire.....

so i had a look at the fuses in the boot next to where the battery is and pulled plasic surround out looked to see what wire was running to the 10a fuse for alt s (guessing alternator) to find that it is an aqua (light green) wire but this wire is about as thick as the wires coming out of your computers power supply.....

so is this the wire that charges the battery? i was expecting to find a much thicker wire for this?

Can anyone shed some light on this as im still not 100% sure about this.

it'll be burried with some other cables in a plastic tube wrapped in elec. tape. this is what it looks like on my R32 gtr. notice the 'stray' wires, it is/was burried amongst these in a plastic tube.

hope those pics help

This is only a guess, but i would bet the wire goes up to the fuse box in the engine bay.

Battery is in the boot so its got to get to it somehow....
