how to connect this to 4 big truck battery?
Undisclosed
Depends what you want to do; are you adding 3 batteries to the existing one and want to keep one always connected? Or do you want all 4 to be isolated?All the black/negative terminals should be wired together and to the frame with heavy gage cable.All the red/positive terminals of the group you want isolated should be wired together, then to one side of the switch. The other side of the switch goes to the alternator (and non-isolated battery if that's the setup you want).It's best to switch when the engine is off and no load, to keep from chewing up the contacts, but this is a beefy switch so it can take some abuse.If you are going to isolate ALL the batteries from alternator, you definitely don't want to switch when the engine is running, you can damage the alternator or other electrical parts. As long as one or more batteries are connected to the engine, you can switch the others "live".Keep in mind the starter can pull 500-1000 amps, and a big alternator can charge at 200A or more, so you want to use heavy 0 or 00 gage cable for this.
