How do I install a larger alternator???
Well i bought a new alternator from Zach last month and I really need to get around to installing it.
It is the 170amp one sold on jusnesmodified.com in case that helps. I am not too concerned about the actuall putting it in, but more of how do i do the wiring? Zach sent a piece of wiring with it, i don't know if that was provided by jusnes or not, but where and what type of fuse, if any, is needed?
Any other helpful info. would be great!!! The sooner i get it in, then the sooner i will install my new off-road lights

the wire came with the alternator. by my understanding when wireing it up is it needs to be ran from the alternator to the battery. with a 170-175 amp ANL fuse and fuse holder. like they use on AMPs and alike.
that is all the wireing i think is needed. everything should just hook right back up

There are two designs: fuse link, and fuse. Either one works. I used a big industrial 250 amp fuse on my 200 amp unit.
Jacob, proceed as follows:
1. Take off the negative battery terminal and leave it off.
2. Unplug the harness wires from your old alternator.
3. Take off and tape up the original 8 gauge wire going to your alternator. You won't be using it anymore.
4. Remove the belt.
5. Remove the 3 bolts that hold the old alternator down.
6. Remove the alternator -- might have to take off you intake tube.
7. Put the new one is place and bolt it in.
8. Put the belt back on.
9. Plug the harnesses in.
10. Attach the new wire to the alternator, and I believe the other end right to the battery. I did it that way, but maybe he intends it to go to the junction box, don't know. I make up my own wire anyway.
11. Reconnect the battery.
That should be it. Fire up and go.

Mine is ty-wrapped to the radiator bulkhead on top, lol. But my fuse is HUGE. I have a piece of old radiator hose around it to protect it.
Just find a secure place to mount it, and secure it so it doesn't whip around.
My fuse is in the middle because I couldn't make up my mind. But I think the fuse has two purposes:
1. To limit the max current taken FROM the alternator.
2. To prevent it blowing up if it shorts and battery power flows INTO the alternator.
So, since the battery is ALWAYS "hot", I think it would be better closer to the battery. But, depending on what faults, it might not matter. If the cable from the alternator to the fuse shorts, then the fuse won't help obviously. Six of one, a half dozen of the other as they say...
Fusing should be at 10 to 25 percent over the rated alternator output generally.
