A custom built system for the D19 Tractors. This system replaces the OEM "DN" series external regulated Alternator and Voltage Regulator with our new "SI" series Delco internal regulated Alt. No need for an external VR and wiring. Get rid of all that old stuff and upgrade! Our Alternator bolts right in place of the old "DN" series Delco. One gauge heavier wire used throughout the new system gets rid of voltage drop, and makes a nice complete kit! Voltmeter replaces the Ammeter for safety and more reliable charging information.  
 
If wanting our optional high amp Ignition switch, move to our 1503-09C kit.
