The electrical schematics referenced above require several corrections. The numbered corrections appear below:
1. The dashed line denoting which components are located in the operator platform does not encompass the 8T-7237 Transmission Neutral Switch (location D-4). The 8T-7237 switch IS LOCATED in the operator's compartment, and the dashed line should be extended to encompass the component.
2. The component location table on the back of the schematic needs to be modified accordingly. The "Switch - Transmission Neutral" is listed on the table three times, at schematic locations D-4, I-5, and L-8. This multiple listing is because the switch is shown on the schematic in the standard configuration (D-4), and in the optional "EMISSIONS ENGINE" (I-5) and "ALL WHEEL STEER" (L-8) configurations. All three of these components list machine location 24. This refers to the adjacent Machine Harness Connector and Component Locations illustration. The correct location for all three configurations is "E" - Operator Compartment.
3. The machine location of the "Switch - Loader Transmission Neutral" is also listed incorrectly on the component location chart. The chart incorrecly lists the location as "G" - Under Cab Floorplate. The correct location is "E" - Operator Compartment. In addition, the switch at location L-8 discussed in the previous paragraph needs to be renamed to "Switch - Loader Transmission Neutral". The following chart shows the correct locations and names of the components discussed in this article:
4. On the Machine Harness Connector and Component Locations illustration, callout number 5 needs to be repositioned. On the overhead view of the machine, it needs to be moved from the left to the right side of callout 11. On the side view of the machine, it needs to be moved to just right of callout 18. On this schematic callout 5 refers to the thermostart coil. See the corrected illustration below.
