(1) 20 foot Ground 16 gauge cable
(2) #10 Spade/lugs to connect battery isolation relay
(2) Quick Splice connectors to connect switched (key/ignition) 12 volt positive and ground from vehicle to small posts on battery isolation relay. Relay ‘closes’ with key or switch (engine) ‘on’ connecting both batteries to charging system, and ‘opens’ with key or switch ‘off’ to isolate main / start battery from any load that can discharge main battery.
This easy to install, high-quality system prevents discharge of your main / starting battery by drawing all 12 volt DC loads from your auxiliary battery with engine off, yet charges both batteries when your engine is running. Never have a dead starting battery again!
