I looked up generator wiring diagram, ion 1--2.2L engine. note the wiring diagram, I don't see a fuse. Make sure battery has a full charge, use a battery charger if needed. All battery connections good. Do you think generator itself might be faulty? See bat terminal at generator, check for voltage, hot all the time. You can use test light or digital multimeter to check for voltage. Key off, if no voltage at generator bat terminal, you'll have to check that wiring circuit from generator to battery. As you can see, generator is controlled by pcm. Two pcm wires to generator, 1 appears to be excite voltage, the other cycles field circuit on and off to control output. You need to do some testing. good luck
