• Ensure adequately sized cable is used.
• Ensure the auxiliary battery and loads
are properly grounded to a common
chassis earth point.
• Ensure the SBI12-LLD ground wire is
making good contact with the chassis
ground point.
• When using fuses make sure that the
fuse makes a good low resistance
connection.
• Fuse/Circuit Breaker ratings are
dependent on the type of installation
and the size of the loads.
