The Sand Pro 3040/5040 machines use 2 fusible links for circuit protection. The
fusible links are located in the machine wire harness. One fusible link connects
the starter solenoid B+ terminal to the fuse block at pin 2. The other fusible link
connects the voltage regulator to the fuse block at pin 1. If a fusible link fails,
current to the protected circuit is interrupted; refer to
additional circuit information.
1. Park the machine on a level surface, lower any attachments, engage the
parking brake, set the key switch to the O
from the switch.
2. Disconnect the negative battery cable from the battery terminal, and then
disconnect the positive cable from the battery; refer to
Installing the Battery (page
3. Locate and disconnect the machine wire harness connector for the fusible
link to be tested:
• at the starter solenoid B+ terminal
• at the voltage regulator output
4. Lock washer
5. Stand-off nut
6. Starter motor (left side of engine)
Check the harness connector for damage or corrosion and clean or repair
if necessary.
4. Use a multimeter to ensure that the continuity exists between the
disconnected connector and fuse F1 (fuse block pins 1 or 2).
5. If any of the fusible links are open, repair or replace the machine wire harness.
6. After you complete the testing, connect any disconnected machine wire
harness connectors. If the wire harness connector at the starter solenoid B+
terminal was disconnected, tighten the stand-off nut to 5.6 to 6.7 N·m (50 to
60 in-lb). Apply battery terminal protector to the starter solenoid B+ terminal
