battery draining every night
have a 95 land rover discovery that is draining the battery every
night? any ideas as to what could be doing it? No lights no radio are left on but something is draining it and its driving me nuts Any help would be most welcomed -- Posted using the http://www.autoforumz.com interface, at author's request Articles individually checked for conformance to usenet standards Topic URL: http://www.autoforumz.com/4X4-batter...ict112223.html Visit Topic URL to contact author (reg. req'd).

Disconnect the main battery cable and place a volt meter in series. If there's any kind of power draw you'll get a reading on the meter. Now start pulling fuses until the power draw disappears. Sounds simple, doesn't it? Unfortunately, with modern computer controlled cars it's often more difficult than that. If you can't find the offensive circuit, you'll need get schematic and find all the circuits that don't go through the fuse box. It can be a very tedious process. -- ..boB 1997 HD FXDWG - Turbocharged! 2001 Dodge Dakota QC 5.9/4x4/3.92 1966 Mustang Coupe - Daily Driver 1966 FFR Cobra - Ongoing project |

Did you measure current draw when off? Don't do one measurement, but
monitor it for a while. Did you test the battery? Either could be your problem, but without tests you'll never know. If the battery is over three years old, maybe a good idea is to replace it anyway.

I think you meant ammeter (or multimeter in A(mmeter) mode, not voltmeter)
in series. > Disconnect the main battery cable and place a volt meter in series. |

Try it. That'll work for a rough indication. If there is any leakage path with an impedance significantly lower than that of the meter, you'll read battery voltage. Once all circuits are open, the VM will read zero (since the load side of the meter is effectively disconnected, just like waving the probe around in the air). The voltmeter trick is safer than an ammeter in the event too large a load is connected unexpectedly. The ammeter will either blow a fuse or smoke. -- Paul Hovnanian ------------------------------------------------------------------ f u cn rd ths u r usng unx |

Remove the negative battery cable from the battery and install a test light
between the neg. cable and neg. battery post....cable end of test light to post and probe end of test light to neg. cable. a bright light indicates a strong current draw... a dim light indicates a weak current draw. Components that run when the key is off will have a static current draw on the battery but not enough to drain the battery overnight unless something is shorted and drawing way too much current. Check the battery and replace if faulty. -- Mad-Dog '79 Chevy K-10 Slightly modified pictures can be found he http://mad-dog16.tripod.com/ -- "jchill43" > wrote in message news:1_527291_c4e5eca8cc6c13d8a1219b2681901520@aut oforumz.com... > have a 95 land rover discovery that is draining the battery every > night? > any ideas as to what could be doing it?
