Battery drain... fuse blew - connect to ballist resister

sure , the ALTERnator swap must be done step #1 battery NEG lug pulled but if not the HUGE alternator fuse blew up.
jumper start engine,
now with a running engine battery voltage 13v to 15vdc
bellow that is dead ALT.
dead means, off line, , or fuses blew. (1 ,2, or 3 fuses)
offline means battery shorted or open it goes off line. not bad.
that is answer #1 and test #1 on all cars. (not EV)
now problem #2 and its testing
called PHANTOM drain, I have posted this 5 times here.

key off.

1. charge battery fully,
2. using and amp clamp meter, DMM + clamp ,connect the AMP clap to the battery + plus main huge cable. (5amp meter range is good)
3. max allowed amps is 0.050a. or 50mA. max. if see 1000mA that is lamp glowing somewhere, (a wise guess) so test the car in the dark, for lamps on , every inch of car,
4. if still have iillegal drains , pull fuses 1 by 1, out ,and in to see if the drain, goes to spec, or 0amps. BINGO?
5. if one fuse pulled cures it , we the read the service manual pages called schematics, for that fuse, power distribution and then pull all things on that feed until the culprit is found

this answer assumes the scan tool finds nothing bad.

the meter is not expensive at all, and must DO DC AMPS.
AC AMP CHEAPER METER ARE NO GOOD.

40AMPS OR LESS, 500 AMP METER ARE FOR SOLAR ARRAYS.

alternator , steps.
1: remove battery main, NEG lug, (if not you blew out huge fuses)
2: remove old starter
3: put in new
4 : reverse step 1.
next time do it correctly.(if true)
the huge fuses are blown, 1 or more, as large as 100amp or larger.
computers just hate, low battery voltage. 10 or below. as they all do discharged.
wire plugs to it not inserterd.
or blew more fuses. small., related to dash cluster.
check all fuses skip none is best.

the Aternator "SYSTEM" can fail for these reasons.
skipping bad alterntor.....
1: bad wiring.
2: bad charge lamp (no, not yours)
3: bad connectors , really same as #1
4: alternator not grounded.
5: battery cables bad. (the 4 corroded ends) or the ground wire
to the top starter bolt, not there, or loose.
6: the fuse blew in the front right fender fuse box. (huge fuse,pulls out)
its not this fuse....
7: belt loose.
8: engine RPM way below 800, 750rpm is spec, mininum.

the alternator regulators on all cars , can in fact shut itself down.
this confuses many car fixers.
It will shut down, if.
over voltatge
if over current.
or sees the battery as being, bad, (high internal resistance or OMG not connected.
its really, mostly a 1995 toyota corolla.

facts.
the regulator is inside the alternator;
there are 3 fuses, that can kill it.
IGN, not this one, because that kills spark too.,
GAUGE, not this as that kills the charge lamp.
ALT-S fuse, BINGO?>

the 100amp fuse is not blown or many things on this car die.
to find this cause, takes one tool, a voltmeter.
doing simple tests.

he forgot the alternator fan bet
he forgot the alternator connections 3 or more.
or forgot to pull the battery lugs first (neg first) and blew out the fuesable link (or fuse).

Disconnect the battery, and connect an ohmmeter to the battery clamps (not to the battery, but to the car's now-disconnected cables). You will see a resistance, rather than the infinite resistance you should see. Make sure the doors are shut, and the under-hood light is removed, or otherwise guaranteed to not be trying to light.

Remove one fuse at a time. (You will probably need to have the door open to do this. Make sure the dome light is not trying to light — remove the bulb(s), have someone hold the switch in the door-closed position, etc.) One of the fuses you pull will cause the meter to start reading an infinite resistance, but will go back to the 200 to 5000 ohms (or whatever) you saw before you pulled the fuse when you put it back in. That is the circuit that is draining your battery.

A resistance of 20,000 ohms or more would be considered infinite in this test.

Do the fans run properly and shut off when cars is off? If not they may be draining the battery. A bad stock antenna could drain battery because of the control module. Also the central locking pump if it keeps running (its supposed to shut off after 30 seconds) but if it fails it will drain the battery.

Disconnect each system 1 by 1 or pull fuses 1 by 1 to find out. I would believe its your neutral safety switch tho. Its on the transmission.

Get a ammeter connect it to the battery negative post and the battery's negative cable . then start pulling fuses until the voltage returns to normal. The fuse you pulled that permitted this change in voltage is the bad circuit.
Next you have to back probe the circuit starting from its fuse tothe load it supports and determine where the unwanted resistance is coming from . Good luck and keep me posted.

change alternator it is short

look in line fuse follow wire from alt.to bat. and see if there is an inline fuse if not also you can check fusable links they sometimes wont break completly

mike , if you have and can use a digital multi meter with amps , disconnect the negitive battery cable , set your multi meter to dc amps , connect it inbtween the battery neg cable and the battery neg post on battery , we are looking for a draw of over 30 miliamps , that is acceptable . keep the car doors closed while doing this test , under the hood find the fuse box and start pulling fuses 1 at a time , note any decrease in draw , lets say you hook up meter and see 300 miliamp draw , not acceptable , pull a fuse and wait for a moment , if no decrease reinstall that fuse and go to the next , if by pulling all fuses you haven't found the problem circuit , the altenator is a good sourse of drain sometimes , disconnect all the wires to the altenator , note any change . remember 30 miliamps is acceptable on a kia. post results when done .


cheers , you found the problem circuit , will you continue diagnostics or call it fixed ?
