You have to disconnect the ground wire from the block. You have to disconnect the positive wire from the starter and the alternator and the powerline going to the fuse box. and connect the new ground then the positive
You do not connect any wire from the alternator to the starter. The positive wire from the alternator should run to the positive on the battery, and the negative wire (if equipped) should run to the engine block (or any suitable ground). Most alternators are already grounded by the bolts holding them to the engine, but some do have a negative wire.
It Depends. Is is a new style alternator? or old generator? if it was the old style generator on the tractor it will be positive ground. If it was the alternator is is negative ground.

The correct way to jumpstart a 2006 BMW 325i is to connect the positive lead to the positive terminals on each vehicle. The negative leads are then attached to a strong ground like the alternator bracket.
There isn't a fuse for the alternator. The alternator is belt driven, and there'll be two lines coming from the alternator - one goes from the alternator positive to battery positive, and the other goes to ground.
Yes connect the positive first to the positive battery post, and then connect the negative ground to the engine somewhere and not to the battery.
Following the cables into the engine compartment. The positive cable will run to the alternator or the starter. The negative cable will just connect to a ground source (engine block, frame, etc.)
I've found it best to connect the pos first then the negative last. If you connect the negative first there is a good chance that you might accidently ground out the positive against some part of the car.

Removing the Alternator Disconnect battery ground cable Remove the ground wire (black) from the alternator Disconnect the positive wire (red wire held on by a retaining nut) from the back of the alternator Now disconnect the wire harness from the alternator Remove the drive belt NOTE: Some models use a belt tensioner that applies tension to the drive belt. The best tool to use for this job is the serpentine belt too. If you can borrow one from a neighbour you can get one at PartSource. (Part# 648451) On other models you will have to loosen the adjusting bolt on the alternator bracket. If you're not sure about how to remove the drive belt, visit your local PartSource for free print outs of vehicle specific instructions. Take off the mounting bolts from the alternator bracket Now remove the alternator from the engine compartment There. You've removed the alternator. How easy was that? Installing Your New Alternator Put the alternator in the engine compartment Install the mounting bolts that connect the alternator to the alternator bracket Connect the alternator wiring harness Now connect the positive wire to the alternator NOTE: Your new alternator should come with a retaining nut. Remember to remove the nut before you install the positive wire. If it doesn't keep the old nut. Connect the ground wire to the alternator Now install the drive belt This is a great time to replace your old worn out belt. When inspecting your old belt look for signs of cracking, oil soaked, hard glazed, splitting or fraying. All these signs mean it's time you replaced your drive belt. If your vehicle no longer has the belt routing diagram under the hood, visit your local PartSource for a free print out of the belt routing diagram. Reconnect the ground battery cable
connect the power and acc wires together and put them on the positive and the ground to the negative
