Hey Guys just installed a Redarc Dual battery isolator to help run all my gizmos and gadgets. Previously i had been just running a 70A relay and i could not keep up.
SO here are all the bits and peices you will need, bar battery and tray.
1. Mount the Smart Start SBI in a convenient location near the start battery bank. Do not mount in direct engine heat.
2.
Its recommend installing a fuse close to and connected to the positive terminal of both batteries. Refer to the chart below for suggested
ratings.
3.
Connect one end of cable of the correct size to the start battery terminal of the Smart Start SBI. Refer to the chart below for suggested cable size.
4.
Connect the opposite end of the cable installed in step #3 to the other end of the start battery positive (+) fuse. 5.
Connect one end of a new cable of correct size to the auxiliary battery terminal of the Smart Start SBI.
6.
Connect the opposite end of the cable installed in step #5 to the other end of the auxiliary battery positive (+) fuse.
7.
Make sure the auxiliary battery is properly grounded to the vehicle chassis.
8.
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.
9.
LED Connections (optional). We suggest installing an external LED indicator on the dashboard of the vehicle. Connect a wire from the “Override” terminal of the Smart Start® SBI to the positive end of an indicator LED (15mA limited current draw) or LED/resistor combina- tion as specified in diagram See Standard Setup Below. Note: a resistor must be used if “Override” switch is connected. Connect the negative end of the LED to the chassis ground. This lamp will illuminate when the Smart Start SBI is activated.
10.
Start Assist Feature (optional). We suggest installing the emergency start switch on the dashboard of the vehicle. Connect a wire from the “Override” terminal of the Smart Start SBI to a momentary push button switch. Connect the opposite end of the switch to the auxiliary battery supply. It is recommended to fuse this wire. To manually operate the Smart Start SBI, hold the switch and the Smart Start SBI will manually operate until the switch is released.
11.
Checking the Operation: The Smart Start® SBI should now be operational. Start the vehicle or apply a charge to the main battery. Once the main battery voltage rises 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 charge to the main battery. The Smart Start SBI will disconnect the auxiliary battery once the voltage on the main battery drops, 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 sole- noid to turn off will vary due to battery condition, age and state of charge.
