## Questions & Answers

**Q: Do I install this before or after a 100 amp bus prewired in my vehicle?**
A: It depends which battery you want to power the bus, and how the bus is wired. If the bus is connected in between both batteries, I would put the isolator before the bus to only drain the accessory battery when the vehicle is off. Once again, depends on how the bus is wired though.

**Q: Is it better to leave the 2 battery connected all the time or its better to disconnect the auxiliary battery if i choose to use a switch**
A: The purpose of the Stinger SGP32 200 AMP Relay is to provide an electronic "switch" that can connect two batteries (or battery systems) at the control of a 1A, 12V signal. In typical use, the relay's signal input is attached to your vehicle's Accessory On, Ignition On or Engine Run signal. In this way, your two batteries are automatically connected by the relay when your vehicle is on and disconnected when your vehicle is off. You could add 1 or more additional manual switches to provide a manual override to the automatic relay.

**Q: What gauge wire is recommended?**
A: You can search google for "Wire Gauge Amps Chart" and that will provide more detailed information on what size wire gauge is required for your specific installation.

But I would definitely recommend using 1/0awg Oxygen-Free Copper (OFC) power wire if your components will be drawing anywhere near 200 amps.

**Q: I have a 210amp alternator will this size work for me or would in need to go bigger? Am i also capable of also using this as a relay without 2 batterys**
A: 1. Your relay capacity should match your alternator, not your load. So you theoretically need a minimum of 210 amp relay. 
2. Yes. It is basically just a solenoid that isolates one terminal from the other until it is activated.
