First thing check you cigarette lighters make sure none are stuck push in or bad. If you do not find any problems there, then you can try taking you negative battery cable off and placing a test light in between the cable and the battery post. You will want to pull out one fuse at a time. Watch your test light; it should get real dim when you find the right circuit that is causing the pull on the battery. The light will not go completely out unless you pull the fuse that carries the memory for the radio out, then it my go out all the way out. There usually is a small amount of voltage being use because of the radio but that will not cause the battery to go down. The battery can carry that. This is the easiest way I can tell you. There are other things you can try but they require special equipment most people don’t have or the knowledge to read wiring diagrams. Nor do they have a working knowledge of electricity to trouble shoot this kind of problem. If you can by chance find the circuit that is causing the voltage draw then you might find the wire or component that is causing you your problem. Look for wires that may have bad spot in them form rubbing on something and laying on metal. If you cannot find it by doing this you will probable have to take it to a shop.

P.S. you don’t have a big amp in this do you because they will kill a battery in about 5 minutes, if you are playing it without the engine running.

Jeep 2005 TJ after battery is charged starts fine but drains within minutes while running .I had my alternate swapped with brand new and still acted same.What is telling Alternator not too produce?


possible faulty regulator or wiring from the alternator
for the battery to be draining noticeably when running one battery lead would be very hot to the touch and it would not start an engine so I suspect that you are forming that opinion from the gauges not showing a charge
that indicates that the alternator is not charging because of broken wires from the alternator or a problem regulator
I would take the vehicle to an accredited auto electrician so that all aspects of the charge system can be checked

What could be draining a brand new battery along with having a brand new alternator?


the alternator is not charging
problems include incorrect alternator ( internal voltage regulated as against external voltage regulated )
blown rectifier plate ( charing with ac current instead of DC)
drive belt tension
best have it checked by an accredited auto electrician

1998 Plymouth Breeze Drains the battery


Check to see that the trunk light and glove compartment light actually turn OFF when the trunk and glove box doors are closed. Also, if one of the diodes on the alternator has failed, it may still test "good." With the car sitting, ignition off, fully-charged battery, check to see if the back of the alternator is HOT. If it is HOT, replace the alternator.

Hello, I have a 1986 Jeep Comanche, 4 cylinder 4x4 5 speed that i just bought used. The battery is brand new, same with cap rotor wires and the alternator i just bought. the jeep kept draining the battery...


If you mean it is going dead while sitting you might have a short or another issue drawing power from the battery. take your truck to your local battery warehouse/store the should have a meter thet will tell you if something is drawing on your system. It could be something simple, like maybe the mercury switch on your under hood light is bad and the light is not turning off thus running your battery dead over night.

MY 1995 JEEP BROKE DOWN ABOUT A YEAR AGO I JUST HAD 3 MAIN FUSES REPLACED A BRAND NEW BATTERY AND A BRAND NEW ALTERNATOR BUT THE BATTERY WON'T KEEP A CHARGE I HAVE A SHORT SOMEHWERE BETWEEN THE FUSE BOX...


Have you checked the charging of the alternator at the battery? (not by a parts store) Put a volt meter across the battery and check voltage while running. You should be showing 13.5v or better (not over 14) with accessories off, 12.5 or better with everything on including high beams. If you don't, chances are you may have a regulator problem. I don't know how you are checking draw, but you should be using an ammeter placed between either battery terminal and cable (cable removed from battery) Unplug each fuse and watch for a substantial drop in draw. That system will be the one with the problem...then, unplug each component served by that fuse (with fuse replaced) till the draw again drops. That will be the component that is pulling your battery down. You did check the simple stuff like sun visor lights and glove box light?
