Why won't Land Cruiser start? Why don't I have lights inside or outside?

There is no spark. Engine cranks, but doesn't start. Radio and heater don't work. No lights inside or lights out side. Replaced rotor and cap, the primary ignition, the ICM and installed a new battery. When my son hooked up the battery cable on the right hand side, it started smoking(probably because cable wet from cleaning. Asked him to check spark plugs, injectors, but he hasn't done that yet. Thanks for any help.
