 Delco 10SI 63 Amp 12 Volt Negative Ground One Wire Alternator

Perfect for Motor Driven Applications where ease of hook-up and built in regulation are required. 

A self exciting or "One wire" alternator as it some times called, has only one wire running to it., that one wire is the main large battery wire. The Ground or Negative wire from the Battery goes to the alternator case or the frame the alternator is mounted on. The one wire, self exciting alternator uses a special voltage regulator that doesn't need an ignition wire to activate it.

This type alternator only requires a battery wire hooked to it. The voltage regulator contains circuitry that uses the residual magnetism in the alternators fields to determine when to turn the alternator on. The regulator does this by sensing the RPM the alternator is turning. When the alternator gets to a around 1000 rpm the voltage regulator "turns on". Typically you start your motor, rev the motor slightly then the alternator starts charging. This type alternator is commonly used on custom cars, trucks, tractors and other non standard applications when wiring is a factor. Also, when using the self-exciting alternator on tractors or other slow turning motors you must consider if the engine has enough RPM's to start the alternator charging. This can be overcome by using a smaller pulley. The included pulley is 2.6 inches in diameter with a single 3/8 V-belt groove.
