Battery drains are hard to find. But with a test light that works when one end clips on ground and the other touches power lights up. Then take the point and stick it in the center of the negative post and clip the grounding side to the body it will not light then slowly lift the cable end off the battery if it lights you have a drain. it must be done in this manner because if you disconnect the battery and install test lamp it resets timers in the car and will show a drain that is not a problem.. If the light is lit remove fuses until light goes out now you have found your drain.

My taurus wont start

If your alternator and starter is good. You might have a dead cell in your battery, If your battery checks ok, then you have a bad ground= corroded or broken wire.

New battery drains.

I can't imagine how changing the belt would have any effect on the electrical system if the alternator is working.
The way you check for a drain is to disconnect the battery ground cable and use a test light to make the connection between the battery and ground. If there is something drawing power from the battery the light will glow.
Then you pull each fuse from the fuse boxes until the light goes out. You also disconnect the starter and alternator if necessary.

My 1998 kia sportage does not start, something is draining the battery, had the alternator, started and battery tested, all good. So what's draining the battery!

The #1 most common cause is lights being left on or lights coming on at night when the temperature drops. Lighted visors are a common problem.

Starting problems

You probably have something that is staying on and draining the battery. You need to have an "ignition off draw" test done.

Have your battery load tested. It sounds like overnight it's slowly losing it's charge. Another possibility is something electrical is "on" or draining battery overnight.

Put in new starter, alternator, & battery but drains it & dies.

It does not take much to drain a battery e.g interior light left on over night etc. OK switch everything off, disconnect the negative lead and fit a multimeter between the battery terminal and detached lead. Set scale range to 1amp. It should read near zero. Methodically remove and reinsert the fuses one at a time noting any changes whilst each fuse is removed. By a process of elimination you will find the fuse that it responsible for draining battery current. This fuse corresponds to the electrical circuit within which there is some fault or short. The starter is unlikely to blame since once the car is running the alternator will more than compensate for any current loss. Just a thought the truck is getting on in years so it could be worth also checking some of the mechanical items that might upset the running if not now certainly in the future: Exhaust GAS Recirculation (EGR) valve and inlet, Throttle Position Sensor (TPS) and Idle Air Control (IAC) valve. All are located fairly close to the throttle body and are really easy to overhaul on a preventative maintenance basis. If you don't know what they are look them up on Youtube

New battery, new alternator, new starter. Battery

Something is draining the battery most likly a short somewhere in the electrical system. You will need to have it looked at by the garage to find the short A temporary or cheaper solution may be to disconnect the battery when not using the car. You can either fit a switch inside the car or physically disconnect it at the battery.

Something electrical is draining battery on 1987 XJ6;

Have you checked the alternator? The alternator may not be charging the battery. With engine running, check the voltage at the battery (it should be ~14V). If it's less than that, your battery won't charge properly. You can take your alternator to auto store to have it load tested also to be sure. Sometime alternator issues don't show up until it gets hot. Defective alternators have also been known to drain the battery after the car has stopped.
