drained battery

[Jerry Roberts]

 Something drained my battery .  I notice that when I disconnect my recharged battery at the terminal that a small spark appears . Am I correct in thinking that when I  put a test light between the battery terminal and the battery terminal clamp , that the test light will light  , and that when I disconnect the offending connection , when I find it , the test light will go out ? I will first try disconnecting my ignition switch (2 wires) as it feels a bit sluggish  .

Check your brake light switch

Check Don's suggestion also any always powered functions--Horn relay, dome light, Cig lighter, clock(small draw only, intermittent as posted before?)   if equiped.

 

Happy hunting, should not be to hard,hopefully!

 

Best,

This a sure cure for you drained battery and maybe from keeping someone from stealing your car. Cut oft switch (!0 t0 15 dollars).

A cut off switch will not fix anything.

Well it does fix a battery from going down if you turn oft the system and that for sure.  Now as far as finding the culprite thats another story.

 Got it !  Thanks guys .  I first tested the brake light switch and it was working OK . Doug mentioned the horn relay and I had been working with replacing the horns and some horn wires .  The horns were disconnected at the time of the problem but the horn relay wasn't . I had accidentally energized the low amp side of the relay permanently when working on the horns and the relay was drawing the battery down when parked . Now I don't show any electrical flow between a battery terminal and its disconnected cable clamp , as it should be when everything is off .

Glad you found it!
