Do you know anyone with a ammeter? You need to hook one up to the battery to check for draw. If the draw with the key off is more than .025 amps, then pull one fuse out at a time till the draw goes away. When it goes away, that will tell you what circuit to check. Hope this helps. As for fuse #3, I would have to look at a wiring diagram for that.

Why is battery light on. new alternator and battery 95 geo prizm

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.

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.

Replaced horn fuse and it blew again right away this is a pontiac transport 1997 help

The fuse blows to prevent wire melting and eventual fire! If it blows straight away then there will be a short circuit somewhere in the circuit, which means the electricity is going from the battery positive to the fuse then straight back to the battery negative without any resistance. You would have to follow the wiring and test components until the fuse no longer blows. :)

I have a 2004 Dodge Sprinter 2500 long body high rise 10 passenger van with continual electrical problems, right now its draining the battery in one or two days. all lamps are out, nothing visible is...

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.

I have 1989 300e mercedes. If i drive and let sit overnight it will not start. Battery dead. I replaced the battery and alternator. If i charge battery for less than 5 minutes it will crank and start up....

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.

I have new batery and the aultinater is fine but something is draining my battery?

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.

KIa Sedona Battery Problem

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 ?

Battery drains overnight

You seem to have more than 1 problem. First the alternator is not working efficiently need to be replaced. Secondly the battery doesn't seem to hold a charge. More than likely needs to be replaced. About the drain if there is a drain and you want to know where it is follow these simple steps.
1. Get a regular test light remove negative battery lead and connect clip on end of tester to the battery cable and the point end to the negative pole on the battery.
2. With everything off and all doors and all lights off the test light should be out.
Open a door or turn on lights any thing that will need power from the battery and tester should light up.
Note: I when everything is off the tester is light go to fuse boxes (REMEMBER ALL DOORS HAVE TO CLOSED WHEN DOING THIS, ANYTHING THAT DRAWS POWER MUST ALSO BE OFF VERY IMPORTANT) remove fuses one at a time when you take it out if the light is still on replace immediately and move on to the next and so on. When you pull the fuse of where the drain is coming from the test light will go out. BINGO you have found the source of your drain. Old good secret I learned years ago in Mechanical School. Good Luck and get in contact if you need more help. If this takes care of your problem just leave me a FIXYA thanks.
