Frequently Asked Questions Does installing this kit void my factory warranty? No. Because this is a non-intrusive “straight-to-battery” connection, you aren’t tapping into the fuse box or cutting factory wires. It functions as an independent add-on, keeping your factory electrical system intact. Why does the LED stay on after the engine is turned off? This is normal behavior. The LED indicates the isolator is still connected. To test disconnection, briefly turn on the headlights—the LED should turn off, confirming the isolator has opened the circuit. Can I mount it without drilling holes? Yes. The kit includes 3M Dual Lock™, allowing you to mount the unit securely without screws. It can also be left suspended if preferred. Can I mount it without drilling holes? The kit works with most 12V battery types (AGM, gel, standard lead-acid). It is not recommended for lithium batteries unless specified. What is P.E.P.® (Proprietary Efficiency Programming)? P.E.P.® is TrueAm’s smart logic that optimizes battery protection and charging efficiency.It ensures the isolator only connects when safe and beneficial for both batteries Does it regulate charging amps? No, the SBI doesn’t regulate amperage. That’s handled by your alternator and voltage regulator.The SBI simply controls when the second battery is connected based on voltage thresholds. Can I manually override or shut it off? The male connector underneath can be wired for remote shutoff.Inline switches are optional but not required—SBI handles disconnection automatically. How do I monitor battery status? Optional Single Meter Dual Display (SMDD) shows real-time voltage for both batteries.Saves space and simplifies monitoring Is it compatible with all batteries? It’s designed specifically for Chevy Silverado and GMC Sierra trucks, but can also be adapted for other GM vehicles with similar 12V systems
