Kia rio battery light is on when car is running!

all else ok car drives, head lamps work key on and off.? both/
always tell all things bad and good, or work goes hard.
for sure headlamps dead or engine dead. oK>?

well , cars can have 4 fuse boxes
lost the glove box uses guide, chapter fuse?
what is truck light? trunk?

i will now read the service manual to you, from on line top site.
for the room and trunk lamps
2 fuses must be good and sure the huge car battery good.
room 30 fuse
or this
X03 - IG1 fuse is blown for sure.
X03 means (Korean?) engine fuse BOX

see engine fuse box next at X03

Try changing the plugs and or plug wires.

Weak fuel pump, (check fuel pressure) Im leaning towards a Clogged catalytic converter as its the most common overlooked problem that will cause a car to run for a bit after it sits a while, only to not restart immediatly after it stalls, but will again start after some time.

undo the alternator bolts and swing it inwards towards the block,replace the belt and lever the alt away from the block to tension it (1/2"play on longest stretch between pulleys) use ring spanners.(wrenches)

You have already figured it out but don't know the answer <(^_^)> . It's the alternator.

well spend some change and have a simple tune-up.  Plugs and filters and readjust the idle.

I would guess starter fuse first, then starter. When you turn key, if you don't hear a click, you should focus your attention on the fuse first and then the starter. If you hear a click, then most likely (80%) its the starter solenoid. try to start the car in neutral to rule out the neutral safety switch...good luck

Does the fuel pump stay running at all like when you shut off the engine?
