Proceed as follows:
1. Verify that the generator is turned OFF. A red LED on the control pad illuminates to confirm that the system is in
the OFF mode.
2. Pull up rubber flap covering fuse holder and remove 7.5 amp fuse.
3. Check the fluid level of unsealed batteries. If necessary, fill with distilled water only. DO NOT use tap water.
4. Check the state of charge using a Digital Multimeter. Recharge and retest if state of charge is below manufac-
turer's recommendations. Replace battery if necessary.
5. Install battery onto battery tray.
Always connect the positive battery cable first. If the positive cable should contact ground with the
negative cable installed, the resulting sparks may cause a battery explosion which could result in seri-
ous injury.
6. Install battery positive cable (red) to battery positive (+) terminal. See Figure 6-4.
7. Install battery negative cable (black) to battery negative (-) terminal.
NOTE: Apply Dielectric grease to battery terminals to prevent corrosion.
8. Install red cover over battery positive (+) terminal.
