1.
Connect your start battery to the isolator.
- Using the supplied red cable (26"/650 mm) with a single lug connector, connect
it to the terminal stud marked "START BATT " on the bottom of the isolator using
the attached lug connector. Remember to secure the cable on the stud using a
supplied washer and nut.
- On the unterminated end of the red cable, strip the end to the correct length.
Then fasten the stripped portion of the cable to the positive terminal on the
start battery.
Depending on your battery terminal type, you may use the supplied separate lug
connector and heat shrink tube so that the red cable can be securely fastened to
the battery's positive terminal through the connected lug.
2.
Connect the second battery to the start battery.
Using the supplied black cable, connect the negative terminal on the start battery
to the negative terminal on the second battery. Make sure to tighten the ground
connection for safety.
3.
Find the black ground cable which is pre-attached to the bottom of the isolator.
Fasten it to the metal frame (chassis) on your vehicle using the attached ring
terminal and a suitable screw (not included). Make sure the ground contact point is
clean (no paint coated) and the connection is tightened.
4.
Reconnect the negative terminal on both batteries only when the isolator mounting
is completed (see the section "Mounting").
