Same kit as our 1503-08A kit less our high amp Ignition switch. Same heavy circuitry throughout the system.  New plugs, and terminals. Includes new 10 "SI" Alternator and Voltmeter. A nice replacement system for all D17 series Tractors! One gauge heavier wire rids voltage drop throughout the system to components. Designed to work with OEM Ignition switch. 
 
B&B TECH TIP:  If wanting to add more circuitry for accessories, move to our 1503-08C kit with HD Ign. switch.
