g223020
The Groundsmaster 3280-D and 3320 machines use 3 fusible links for the circuit
protection. These fusible links are located in a harness that connects the starter
B+ terminal to the wire harness
fail, current to the protected circuit stops; refer to the Electrical Schematics in
Appendix A (page A–1)
1. Ensure that the key switch is in the OFF position, disconnect the negative
battery cable from the battery terminal, and then disconnect the positive
cable from the battery; refer to
2. Locate and unplug the fusible link connector P1 from the machine wire
harness.
3. Use a multimeter to ensure that the continuity exists between each terminal
pin in the connector P1 and connector J1 at the starter
4. If any of the fusible links are open, replace the fusible link harness.
Note: Do not replace individual fusible link conductors of the fusible link
harness. If any of the harness links are open (failed), replace the entire
fusible link harness.
5. After you complete the testing, ensure that the fusible link harness connectors
are correctly attached to the starter and machine wire harness. Connect the
positive battery cable to the battery terminal and then connect the negative
cable to the battery.
