Hi Joe
It is sort of a guess, but your headlights are powered from the battery and cause a drain when on, so the regulator provides extra volts to compensate the battery charge being depleted.
Except your question heading says 'not to charge'. The question body says 'why the alternator is charging when I turn the headlights on'? Should that be 'why the alternator is NOT charging when I turn the headlights on? If that is the case, you need an auto electrician.
is battery in good condition. It sounds like you have a bad battery.

tried to shift from park to another gear, the shifter would not move.
There are a few possible reasons why your 2010 Hyundai Elantra may be stuck in park even with functioning brake lights and a replaced brake switch and interlock solenoid. Here are some troubleshooting steps you can try:
1. Check the fuse: Ensure that the fuse for the brake lights and shift interlock system is not blown. If it is, replace it with a new fuse of the same rating.
2. Inspect the wiring: Examine the wiring that connects the brake lights, brake switch, and shift interlock solenoid. Look for any signs of damage or loose connections. Repair or replace any faulty wiring as necessary.
3. Test the brake light switch: Even though you have replaced the brake switch, it is still possible that the new switch is defective. Use a multimeter to check for continuity when the brake pedal is pressed. If there is no continuity, the brake
The fuse is in the engine compartment fuse box and is marked 'A/Con'. It looks like a Relay to me and as it doesn't have an amperage, my guess is that it is a relay. The different sites have slightly different variations, but the thing to check first is the relay. You mention 'heater coil', that is on the engine coolant circuit and only provides hot air. The AC compressor system has an 'evaporator' up in the dash and only supplies chilled air. I trust the AC job was done professionally with a Gas Recovery machine to create a moisture free vacuum before adding refrigerant gas. It can't be done at home. I wrote a Fixya Tip on it.
If your Hyundai H1 2018 model is losing water from the radiator at an alarming rate, even with a new radiator that is not leaking, there are a few potential causes for this issue:
Coolant leak: While you mentioned that the radiator is not leaking, there could still be a coolant leak elsewhere in the cooling system. Check for any visible signs of coolant leakage, such as puddles under the vehicle or wet spots on hoses, connections, or the engine. Coolant leaks can occur at various points, including hoses, water pump, heater core, or even the engine block itself. If you cannot identify any external leaks, it is possible that the leak is internal, such as a blown head gasket or a cracked engine block.
Faulty radiator cap: The radiator cap plays a crucial role in maintaining the proper pressure and preventing coolant loss. A faulty radiator cap can cause coolant to escape from the system. Inspect the radiator cap for any signs of damage, such as a worn-out gasket or a cracked cap. If necessary, replace the radiator cap with a new one and see if it resolves the issue.
Internal engine issue: Internal engine problems, such as a blown head gasket or a cracked engine block, can cause coolant to mix with the combustion chamber or leak into the oil system. This can result in rapid coolant loss without any visible external leaks. Look for symptoms such as white exhaust smoke, coolant in the oil (appearing as a milky substance on the oil dipstick), or an overheating engine. If you suspect an internal engine issue, it is recommended to have the vehicle inspected by a qualified mechanic to diagnose and address the problem.
Improper coolant filling or air pockets: If the coolant was not properly filled or if there are air pockets in the cooling system, it can cause coolant loss. Air pockets can prevent the proper circulation of coolant and result in overheating and coolant loss. In such cases, bleeding the cooling system to remove air pockets and ensuring the coolant level is at the correct level may resolve the issue.
Given the significance of the coolant loss and the potential complexity of the underlying problem, it is advisable to have your Hyundai H1 2018 model inspected and diagnosed by a qualified mechanic or Hyundai service center. They will have the expertise and necessary diagnostic equipment to identify the specific cause of the coolant loss and provide the appropriate repairs or solutions.
WONT CRANK FAST
OR CRANKS FAST BUT WILL NOT START
IT IS ONE OF THOSE.
HEAR IT, CRANK FAST A DEAD ENGINES.
https://freesound.org/people/drdeath666/sounds/687447/
WE CAN NOT HEAR YOURS, HERE.
no engine told, at all, 7 there are
2000 to 2005, gen 3 car.
yes, yes and yes, and are all seen here in photo1 below.
lambda II engines. 3.8L
38 steps, +18 more on step 19, and 56 steps just for removal.
just to get the cover off is 31 +19 steps.
the service manual covers all this
a crank locker and cam locker is needed special tools.(or diy made)
https://eautorepair.net/Marketing/Default.asp
DO not mix cam caps up, each are precision made and matched to head exact spot location. cams block head bolts.
gee read the manual first
differ, body but engine is 3.8, and all steps he did 56 steps not show.
he shops step 57 , head off, and coolant pipe off.

the head bolts are TTY bolts set by angle and are never REUSED
TTY= torque to yield.

Install cylinder head bolts.
Do not apply engine oil on the threads or under the heads of the cylinder head bolts.
Using SST(09221-4A000), install and tighten the cylinder head bolts and plate washers, in several passes, in the sequence shown.
Step 1-Tightening torque: 28-30 ft. lbs. (37-41 Nm)
Step 2-Tighten an additional: 120° plus or minus 2°
Step 3-Tighten an additional: 90° plus or minus 2°
Tighten bolt (A) to: 14-17 ft. lbs. (19-24 Nm).NOTE
Always use new cylinder head bolts.
Uniformly loosen/tighten and remove/install the 16 cylinder head bolts, in several passes, in the sequence shown-3.3L and 3.8L engines
NO YEAR CAR TOLD OR COUNTRY 1997 to present, not told
is this a UK car RHD right hand drive,, drive on right side?
called also in UK Hyundai H-1 a VAN.
NO LAMP TOLD! (guess right side car and guess right side park dead not right side blinkers, correct? not told
CARS HAVE A BUNCH OF LAMPS.
THE CARS USERS GUIDE COVER THIS. GLOVE BOX, LOST?
front lamps, rear lamps
or side park lamps
reverse lamps, parks, turns, blinks, brakes or side of lamp park lamps.
sorry I cannot guess them all all 4 sides,ends are all different
or say RIGHT park lamps dead. (or 1 of 2 there) if true.
the manual is by year not told so showing it to you is impossible
will millions of transmissions "A/t fail all other the world. endless'
at 250,000 miles if lucky that far. no miles told (car/tranny)
not told this
what does the tranny do (PRNDL)
in reverse and (told)
in DRIVE (yes stick in low )_ but what is rpm now.????? stuck low or screaming in 1st gear . a weak engine will be low rpm in 1st gear.
and low,
no country told and is a super key factor on scan tools , got one?
we can scan all ours (USA) 1996 up every one.
tranny fails hot and cold
tranny filter ok?
if the PCM sees solenoid errors. (scanned) it will not upshift.
if the PCM seen speed sensors fail it can not upshift.
need I go on there are 50 more cause.
but most are leaking seals in the box and the poor atf pump can not handle that.(most boxes die of this latter end of life event)"
internal leaks)
steps 1 to 5
1: fuses good
2: levels good. hot in park,idling
3: scan the PCM for TCM errors.
4: check shift linkage for bad.
5: to the pump port pressure tests PRNDL per the service manual
above asssumes engine is good,is it? not weak as a cat or in silly
TBW limphome .(limited) scans tell this ,why skip scans/?
