Electronic Battery Isolator
12V / 24V Negative Ground Charging System
Operating Instructions
Please read these instructions before use
The GSL Electronic Battery Isolator range feature electronic current
limiting, which operates when the isolator is subject to overload
conditions. This setting will allow both main and auxiliary batteries
to share available power while still giving priority to the main vehicle
battery in the case of a heavily discharged main battery.
Warning: Before commencing work ensure that the negative terminals from the main and auxiliary battery have been
removed. Do not short any wiring to bodywork except the black earth wire.
Wiring Instructions
1. Mount the isolator high up in the engine bay away from moisture and any source of external heat
e.g. exhaust systems.
2. Scratch away the paint from the body surface and earth the black wire onto the body.
3. Connect the red wire to a ignition switched power source e.g. voltage side of the coil and the voltage side of the
ignition switch. On EFI vehicles the accessory circuit can be used.
4. Connect the main battery terminal (Right hand side of isolator), using 6 B&S cable to the positive terminal of the
main battery.
5. Connect the auxiliary battery terminal (Left hand side of isolator), using 6B&S cable to the positive terminal of the
auxiliary battery.
6. Ensure that the second battery is correctly earthed using a minimum 3B&S cable.
7. Ensure that battery voltage on red voltage sense wire is as close as possible to main battery voltage.
Note: Any variance should be within 0.2 volts.
Note: When installing the battery isolator, it is recommended that you fuse the red
voltage sense wiring and that winches are powered from the main battery. Power
secondary auxiliary loads such as fridges, lights etc from the auxiliary battery.
