Secondly, it ensures that any electrical accessories or devices that are connected to the positive terminal of the battery are isolated from the vehicle body, which could be at a different (and potentially unsafe) voltage. Firstly, it helps to prevent any accidental shorts circuit between the battery and the vehicle body. There are a few reasons for this convention. This is because most vehicles are “negative earthed” – that is, the body of the vehicle is connected to the negative terminal of the battery. When connecting a battery isolator to your vehicle, the convention is to put the isolator on the negative lead. It turns off when the isolator is protecting your starting battery.ĭo You Put A Battery Isolator On Positive Or Negative? A green light indicates proper operation. Step-15: Remove the negative probe from the battery and place it on your ground point. Step-14: Make sure all your connections are safe and tight, then test for a proper ground by placing the voltmeter probe on the positive and negative auxilary battery terminals and note the reading. Step-13: Leave a green LED light on to indicate proper installation. Step-12: Finally, attach the 12in black cable to the negative lead on the auxilary battery, then attach the other end and the vehicle’s negative cable to the starter battery’s negative lead. Step-11: Then attach the 24in red cable from the isolator and the vehicle’s positive cable to the positive lead on the starter battery. Step-10: Attach the 12in red cable from the isolator to the positive lead on the auxilary battery. Step-09: Attach the ground wire from the unit to a bare metal spot close to the battery.

This will hide them both and install it to the mounting plate with the two remaining longer 38mm screws. The other 12in red cable attaches to the remaining underside bolt. Step-08: Having done that, attach the end of the 24in red cable to the underside bolt. Step-07: Test the fitment in progress to determine wire runs and which of the eight base punch outs will be used in your configuration. Step-06: Install the insulated ring terminal on the black ground wire attached to the isolator unit. Prep it and use a moderate heat source to shrink the including cover. Step-05: Strip 15 to 20mm of the unterminated end of the 24in red cable and install one of the two lug connectors provided. Step-04: Attach the mounting plate to your chosen location. Drill the holes following the template you made using the two 19mm screws included. Step-03: Remove the lower mounting plate from the unit and use it as a template for marking the board. Avoid placement near hot exhausts and keep it as close to the starter battery as possible, preferably where it’s LED can be seen. Each vehicle is different, so the location point is important. Step-02: Install your auxilary battery next to your starter battery. Step-01: Locate the battery on your vehicle and disconnect the negative wire first for safety, then the positive wire.
