Conduct a survey on the type of motor you are going to purchase. Take keen notice on how the pulley of each motor is attached to it, as you will need to replace it. An ideal motor should have two holes as a single hole at the end of the shaft would mean wastage of a lot of time in trying to figure out how to fix the pulley.
Lay all your items on the floor of your workstation as this will help you determine whether all the requirements needed are present. Another purpose for this is to determine the amount of base space that is required for the assembly of your generator. Cut the plywood appropriately using the saw to fit your base space.
Loosen the bolts fixing the pulley that came with the motor using the spanner. Carefully install the new pulley into position and fix it firmly using the bolts. Use 2 bolts to fix the adapter bracket onto the motor, then bolt the alternator to the bracket using two other bolts. Drill four holes at one side of the plywood to help in the mounting of the motor. Fix the bolts to hold the motor firmly in position.
Leave a space of three inches between the rear end of the alternator and the car battery to leave sufficient room for the terminals of the alternator. Place the battery on the opposite end of the mounted motor and use a pencil to draw its outline on the plywood. This will give an approximate figure in dimension to construct a small box. Place the constructed box at the stipulated position -- three inches from alternator -- and fix the wooden box on the plywood. Fit the battery right into the box.
Connect the motor to the battery using the battery cables. The positive end of the motor should lead on to the positive end of the battery and the negative to the negative. Ensure the crocodile clips at the terminals of the battery hold firmly. The generator is now ready for use.
