At the top of this page you will find all of the 10Si type alternators we carry. Positive and negative ground including regular finish and chromed units. The 10Si model alternator, due to its simplicity and longevity, is most common for tractor generator to alternator conversion applications, particularly for Ford 2N, 88N and 9N tractor generator-to-alternator upgrades. Some units use our self exciting, low-rpm voltage regulator for easy hook up.

Help On Choosing The Right 10Si Alternator

First, what is the polarity of your application? Many cars and trucks use a negative ground configuration, where the case has a direct connection to the negative battery post. Tractors and some automobiles use a positive ground, meaning the case has direct contact with the positive post. Next, what voltage do you need? Most cars and trucks use a 12-volt system, but some tractors may use 6-volts. The 8-volt option is very uncommon outside of a custom applications. All of these voltages have different amperage ratings. Amperage is a function of voltage and the number of windings on the stator. Higher voltage and a greater number of windings will produce more power in the form of amperes. You can also choose between a standard voltage regulator for direct replacement in a vehicle or a self-exciting voltage regulator for a custom application ( What is a Self Exciting Alternator? ).

Unlike the competition, our Si series, self-exciting units include a special low-speed activation circuit. You don't need to rev the engin
