5. Installazione
Proper installation is crucial for the optimal performance and safety of your Stinger SGP32 battery isolator. Always ensure the vehicle's ignition is off and the primary battery is disconnected before beginning installation.

5.2 Passaggi generali di installazione
- Montaggio: Choose a secure, dry location for the isolator, away from excessive heat or moving parts. Use the provided mounting bracket to firmly attach the unit to a stable surface in your vehicle.
- Primary Battery Connection: Connect a heavy gauge positive cable (e.g., 0-4 gauge) from the primary battery's positive terminal to one of the large terminals on the isolator.
- Secondary Battery Connection: Connect another heavy gauge positive cable from the secondary battery's positive terminal to the other large terminal on the isolator.
- Collegamento a terra: Connect a small gauge wire (e.g., 16-18 gauge) from the isolator's small ground terminal to a clean, bare metal chassis ground point.
- Ignition/Activation Wire: Connect a small gauge wire from the isolator's small activation terminal to a 12V ignition-switched source. This source should provide 12V only when the engine is running or the ignition is on, allowing the isolator to engage and charge the secondary battery.
- Fusione: Install appropriate fuses (e.g., 200A for main battery lines, 10A for activation line) as close to the batteries as possible to protect the wiring and components.
- Ricontrolla le connessioni: Controllare attentamente tutti i collegamenti per verificarne la tenuta e il corretto isolamento.
- Ricollegare la batteria: Reconnect the primary battery and test the system.

6. Funzionamento
The Stinger SGP32 operates automatically. When the vehicle's engine is running and the primary battery is being charged by the alternator, the isolator will sense the voltage increase and connect the secondary battery in parallel. This allows the secondary battery to charge. When the engine is turned off, or the primary battery voltage drops below a certain threshold, the isolator will disconnect the secondary battery, preventing it from drawing power from the primary battery. This ensures your primary battery remains fully charged for starting the vehicle.
7. Manutenzione
To ensure long-term performance of your Stinger SGP32 battery isolator:
- Ispezione regolare: Periodically check all wiring connections for tightness and corrosion. Clean any corrosion with a wire brush and battery terminal cleaner.
- Condizione del cavo: Inspect battery cables for any signs of wear, fraying, or damage. Replace damaged cables immediately.
- Pulizia dell'unità: Mantenere l'unità isolante pulita e libera da sporcizia, polvere e umidità.
- Ventilazione: Ensure the mounting location allows for adequate airflow around the unit to prevent overheating.
8. Risoluzione Dei Problemi
If you experience issues with your Stinger SGP32, consider the following:
- Batteria secondaria non in carica:
- Check the ignition/activation wire connection. Ensure it receives 12V when the engine is running.
- Verify all main power connections are secure and free of corrosion.
- Check for blown fuses in the main battery lines or the activation line.
- Ensure the primary battery is charging correctly from the alternator.
- Primary Battery Draining:
- Confirm the isolator is disconnecting the secondary battery when the engine is off. If not, the activation wire might be incorrectly connected to a constant 12V source.
- Inspect for any parasitic draws from accessories connected directly to the primary battery.
- Surriscaldamento dell'unità:
- Ensure adequate ventilation around the isolator.
- Verify that the current draw does not exceed the isolator's rated capacity (200A continuous, 500A peak).
