SOURCE: alternator not exciting

Hi ' If you changed the battery and alternator,
Check the voltage at the red wire on the alternator. if there a less than 12 volt.
Check the fuse link, that goes in the starter positive bolt.
If the fuse is bad replace and recheck the charging system.
IF charging normal. good.
If not, che the fuse in the fuse box, "" cluster".
If the fuse is blow out, replace. and check again.

OK. I hope this work for you.

SOURCE: I have a direct short which drains both batteries in less than 1h

Remove positive cable from battery & connect a 12 volt test light between battery terminal & battery post. Anytime light is on, you have a draw on battery. Don't forget your stereo will cause a small draw all the time. Light will dictate how much draw, if it's bright, lots, if dim, not too much. If it' bright, and you pull a fuse & it dims down, or goes out, you've found circuit with fair bit of draw. If worse comes to worse, I always find it easier to make sure I know where they all go back to, then pull them all & start putting back one at a time, light will tell you where you have a draw, mark it down, pull it back out & try another, until you found all sources of draw, and recorded the brightest one(s) Now go from there with info you have. If you put one in & no light, you can leave it in. Good luck, at least it will isolate the culprit(s).

Car wont turn over and making a humming noise when key is in on position. when i try to start it the car makes a clicking sound.

the alternator isn't charging battery that would account for loss of power and also clicking when try to start , try a jump start if it starts then you know its the battery so with engine running check the alternator charge rate with a voltmeter across the battery terminals anything below 13 volts then check the alternator belt is tight enough , good condition etc , then recheck charge rate if still low fit new alternator

Van wont start .checked alternator. fuses and brand new battery still wont start. van started acting u when fuse to rad fan went out. engine light came on but since we live in cold area never heated up....

I think you're over your head here. Take it to a professional mechanic and let her sort it out. Sounds like your alternator isn't putting out the correct voltage.

Brand new alternator & good charge on battery when

a couple things,a wire going to the starter could be melted to the exhaust,a bad connection on the battery or starter solenoid ,started could be bad,brushes wore down too low and shorting out,or your battery may read good with a meter after charging but test your battery with a load tester,you may have a dead cell or cells or even a short inside the battery,when you turn the key the battery will short out inside and then all the lights are dim but if you just move the battery cables just a little,every thing looks normal until you try to start it again,this happen to me,every time my boss would try to start our service truck,everything would go dim,fan's would slow,my boss would yell to me,turn the cable to get a better connection,I did this a few times until I was bent down ,to look under the opened hood to see my boss setting in the drivers seat telling me to move the cables more,and every time,just click,then as I was bent over the battery to see my boss,the battery was only inch's from my head,it exploded,covering me in the battery acid,a piece of the top of the battery shot through my hair,leaving me with a gash across my head,with out hair,kinda like a over sized part,but bleeding,the acid never burnt me or hurt me at all,but the sound of the battery blowing up inch's from my head,I couldn't hear all day,just a load humming sound,,,so be care full when working with a battery that could have a short,and never buy new acid and add it to your battery,the two fluids ARE NOT COMPATIBLE,and the slightest spark from static will be enough to explode the battery.

When starting it sounds like it is puttering and then stalls out. If I try to start it again, it wont start. Almost like it is flooded. I have a 1998 ford explorer with a little over 117,000 miles on...

I've got the same (1998 exploder). Someone went through the neighborhood trying to syphon gas. My truck started then sputtered out and now wont start. Gas is showing half tank plus I added 2 gallons Spark is good and gas pressure is reading 40psi(normal). Everyone else's including my 2005 Chrysler Pacifica started. I need help. Did you find something out that may help?

My car started dying and now hasnt enough charge to start

sound like bad battery cables.replace them.the positive battery cable is old and have a lot of resistance not allowing power to the alternator to charge battery.if battery cable good check alternator connector wires.make sure they are not damage also check alternator fuse and fuse link.turn off radio before removing battery wires so you wont lose radio code.

Clicking not cranking. Replaced battery at Pep

Why did you replace battery in the first place Before checking out the reason of why it wouldent start???????????.
1st when you turn the key does the starter motor click
2ndTurn on headlights and then try starting ,do the lights go out (yes/no) 3rdThe Alternator only does the charging not the starting
BUT YOU say you can jump it and it will start ???????????????
Well that still puts it down to either the Starter OR the BATTERY is no good unless you have a24 volt system (which you havent)
So check the Red + lead from the battery to Starter motor for good tight fit ,,and the Black -lead to any engine bolt and also to the body (2 wires 1thick 1 thinner Black leads ) good tight fit ,,
The funny hum you can hear would be the fuel pump working and that is in the fueltank But just check under the bonnet and make sure that
its not coming from the alternator as sometimes it get a short inside and will flattern the battery in 3minutes (that also has a Red feed wire going to it.

The 03 tiburon will not start and it clicks one time and then makes a slight humming noise

This is probably a failed battery to where electrical diagnosis is in order.This test will verify battery and alternator output under load which this will need to 13.6 volts and about 85 amps output from the alternator to pass...
