If your tractor has a 1/2" wide belt you will need to purchace a 1/2" pulley for Alternator, or replace your belt accordingly. Unless you choose to purchase the other Alternator Conversion kit offered on this site that includes the 1/2" wide pulley (pre-installed)
The 12 Volt Alternator is used to convert the 6 Volt system to a 12 Volt system. This Alternator has a simple 1 wire hook up. All you will have to do is run a wire from the Alternator through Ammeter to the positive side of the battery. The Alternator has built in self-exciter. You must rev the engine to 800 - 850 RPM in order for the unit to self excite. This Alternator is meant for 12 volt negative ground systems. The Alternator must be grounded to the bracket. Some of the paint/powder coat must be removed where the Alternator bolts to the bracket for a sold ground connection.
The 12 Volt distributor coil is a barrel style coil and is internally resisted. It includes the coil mounting bracket.
