STANDARD WIRING DIAGRAM
Ensure adequately sized cable is used.
Ensure the auxiliary battery is properly grounded to a
common chassis earth point.
Ensure the SBI 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.
WIRING
1.
Make sure the auxiliary battery negative is properly
grounded to the vehicle chassis.
(1)
2.
Ground Connection. Connect the Smart Start
®
SBI
ground terminal to chassis ground. Remove any paint
to ensure a good ground connection.
NOTE:
A good ground will ensure correct switching
voltage.
(2)
3.
Select correct Circuit Breaker/Fuse sizes and install at
battery end of both positive cables.
(3)
4.
Connect the cables in the order shown as shown
below.
(4,5,6,7)
*When using fuses make sure that the fuse makes a good low resistance connection.
Circuit Breaker/Fuse ratings are dependent on the type of installation and the size of
the loads.
LED CONNECTIONS (OPTIONAL)
Connect a wire from the Blue wire of the Smart Start
®
SBI to the
positive end of an indicator LED (15 mA limited current draw) or LED/
resistor combination mounted on the vehicle dash.
START ASSIST FEATURE (OPTIONAL)
1.
Connect a wire from the Blue wire of the Smart Start
®
SBI to one
terminal of a momentary push button switch.
2.
Connect the other terminal of the momentary push button switch to
the auxiliary battery supply.
To manually operate the Smart Start
®
SBI, hold the momentary push
button switch and the Smart Start
®
SBI will manually operate until the
switch is released. After about 10 seconds start the vehicle with the
button still held on. The Smart Start
®
SBI should now be operational.
