my battery keeps dying

[awdtalon21]

i have a 91 talon and if leave the battery hooked up the battery will be dead in a day, if i disconnect the postive termal it will be fine. my question is there a way to see what is draining the battery? none of the the lights are on in the car.

have you checked to see if your starter is good

If you are having a voltage leak down it may be from the ECU. Check it and make sure the board looks good.

Start checking for draw from various circuits leading away from the battery.

alternator may be bad, it could easily kill a battery in one day if its bad.

i had that same problem twice before, the first time it was my ground wire coming off my battery and the second time my alternator was shot

Saw your other Post - you've got the Headlight relay hot all the time - I just deleted the HI - LO Switch in the column & mounted a Toggle Switch in the Steering Column Cover.

check caps on ecu, i had the same problem not to long ago

1) get alternator tested
2) if alternator is bad get it replaced and make sure you don't have an exhaust leak at the downpipe that is blowing hot exhaust gas on the alternator
3) check ecu caps

hope that helps.
