INSTALLATION INSTRUCTIONS

1. Mount the Smart Start

SBI securely in a convenient location near the start battery bank. Do not

mount in direct engine heat.

2. Install in the order described below:

• Make sure the auxiliary battery negative is properly grounded to the vehicle chassis (1)

• 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)

• Select correct Circuit Breaker/Fuse sizes and install at battery end of both positive cables (3)

• Connect the cables in the order shown on the next page (4,5,6,7)

• LED Connections (optional). Connect a wire from the Blue wire of the Smart Start

SBI to the

positive end of an indicator LED (15mA limited current draw) or LED/resistor combination mounted

on the dash as speciﬁ ed in the diagram on page 3.

• Start Assist Feature (optional). Connect a wire from the Blue wire of the Smart Start

SBI to one

terminal of a momentary push button switch. 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.

• Checking the Operation: The Smart Start

SBI should now be operational. Start the vehicle or

apply a charge to the start battery. Once the start battery voltage rises to the ‘ON Volts’ level

the Smart Start

SBI will activate, you will hear the solenoid click and see the LED illuminate.

Now turn off the vehicle or remove the charger from the start battery. The Smart Start

SBI will

disconnect the auxiliary battery once the voltage on the start battery drops to the OFF Volts level,

you will hear the solenoid click and the LED will go out. Note: The amount of time it takes for the

battery voltage to drop low enough for the solenoid to turn off will vary due to battery condition,

age and state of charge. (For a new, fully charged battery, it may take days). Note: See table on

page 1 for speciﬁ c voltage levels.

NOTE: As per above, the LED may stay ON for a period of time after the vehicle is turned OFF.

RECOMMENDED FUSES

REDARC recommend using MIDI fuses along with a quality fuse holder to match. The diagram below

shows the construction of a MIDI fuse installation (cables not included).

REDARC MIDI fuse kits containing 4x fuses and 2x fuse

holders along with the required nuts are available from

most Auto Electrical outlets.
