200 amp alternator

High-capacity alternator provides plenty of power to handle increasing electrical loads found with today’s optional electronic equipment and electronic control of implements. 

 

  • A 200 amp alternator is standard on all models
  • Located on rear of transmission for cleaner environment
  • Powered by auxiliary drive from transmission input shaft
Two 12-volt batteries

Cover removed, exposing batteries and storage

New battery mount location allows for two 12-volt (925 CCA) sealed-type batteries.  The batteries are located on the left side of the tractor.  The magnetic latch on the access cover is easy to remove for access to the storage tray or to service the batteries.

 
The side-by-side design provides simple battery and cable accessibility.

8030 Series Tractors are equipped with CAN (Controller Area Network) technology. This electronic feature provides additional functions and the computing power required to assure efficient operation. There are other benefits with technology that has simplified wiring and improved reliability.

 
The SmartCircuit portion of CAN technology provides the following features:
  • Fewer fuses and relays
  • Fewer wiring connections
  • Diagnostic capabilities. The SmartCircuit system can detect many circuit problems using the CommandCenter™ display. It will provide information as to where a problem may exist. It can show something as simple as a light bulb not working to a more a more complicated item. New detailed service trouble codes give you or a John Deere service technician more information to quickly resolve a problem area.
  • Ability to easily add features to the electronic system via additional control units
  • Electronic control units have the ability accept updates to operating software. If it is ever necessary to improve machine functions via software, it can be performed without the purchase of an entire electronic assembly. Should service of this type ever be required, your John Deere dealer can do a simple, tractor serial number specific procedure. It is done via use of an online service tool called ServiceADVISOR™.
 
New with the John Deere 8030 Series Tractors, the electrical fuse panel is located under the cover beneath the rear window latch.  
  • Contains easy-to-replace automotive blade-type fuses and relays for quick servicing
  • Only a small number of relays are used; most are visible with the cover removed
 
GreenStar™ Ready wiring
 
The backbone of the GreenStar system is the tractor wiring and connections.  The integration of this harness assures operation with John Deere GreenStar common components. With the 8030 Series Tractors, common components are easily added to the new connecting points.
StarFire™ iTC GPS receiver
 
Adapter harness and receiver wiring

Adapter harness and receiver wiring

The StarFire wiring is attached to the connector imbedded in the cab roof.  When not in use, a connector protector cap is included.


Note: StarFire receivers purchased before April 2006 may require an extension to the wiring harness as shown in picture above.  See AMS section for part number information.

GreenStar displays
 
Cornerpost GreenStar display connector

Cornerpost GreenStar display connector

The display connector that has been added to the cornerpost cover provides easy hookup of wiring.    Via an adapter harnesses, the tractor is compatible with the monochrome screen GreenStar display  (GSD4) and mobile processor or the new GreenStar 2 systems (the 2100 or 2600 John Deere color display).
 
A convenience plug-in for ISO radar-ground speed monitors is also located on the cornerpost.


Adapter harnesses can also provide the ability to operate two displays if multiple needs exist.


Note: Display hookup will require an extension to the wiring harness.  See AMS section for part number information.

Implement connector
 
Implement connector

Implement connector

This connector is in a convenient location to attach implement wiring.  SeedStar™ planters and AccuDepth™ implements use this connector to function.


The implement connector has been engineered to ISO standards that provide compatibility with ISO bus-type implements.  See below for more information on the ISO bus.

Tractor is ISO bus certified
 
The GreenStar Ready feature provides the ability to function with and control ISO bus implements.  The system will support the use of the GreenStar 2 systems (the John Deere 2100 and 2600 color displays) and other manufactures that make ISO bus-type displays.  These displays can control an implement through a function known as VT (virtual terminal).  John Deere has adopted the common standard (ISO 11783) for maximum adaptability of the tractor to today’s and future implements.
Use StarFire iTC or RADAR for true ground speed input
 
There is a breakthrough in abilities of the StarFire iTC receiver.  It can generate a radar-like signal for input of true ground speed into the tractor.  By swapping a simple connector under the CommandCenter™, you can utilize this StarFire iTC feature via the tractor wiring.  Tractor functions such as wheel slip, hitch slip command, and speed readouts on displays or monitors can be activated with this signal.  More information on this connection swap can be found in the tractor operator's manual.


Many applications can use the update rate (speed calculation accuracy) of the StarFire iTC as it is fast enough to provide accurate inputs for most situations.  Some implements, however, will still require the faster update rate provided by the dual-beam radar unit to function properly.  See implement section for ground speed input requirements.

7-pin outlet
 
7-pin outlet for implements

7-pin outlet for implements

7-pin terminal outlet that conforms to ASAE and SAE requirements is standard equipment.
 
Provides electrical power for wagon or implement requirements.
3-pin outlet, cigarette lighter style connector, ServiceADVISOR™ data port
 
3-pin electrical outlet sockets and cigarette lighter style connector are provided on the rear-most end of the right-hand control console.
 
The top socket is a cigarette lighter style connector for many purposes.   
 
The 3-pin connector includes a ''hot'' or unswitched power for maintaining monitor ''memory'' when tractor is shut off.  Use this where current drain is minimal to prolong battery life during tractor off periods. Switched power and ground connections are also included.   
 
The center connector is the ServiceADVISOR data port and is used by a John Deere dealership service technician to access the tractor control units for diagnostic needs or software updates.
 
Rear window wiring grommets
 
Window grommets

Window grommets

Two rubber grommets are located on the rear of the cab to provide easy installation of wiring harnesses that need to exit the cab out the rear window.
 
They are easily removed by sliding upward and can  be cut for fitting various size wiring harnesses.
