Battery goes dead over night

Battery goes dead over night Sign In

We have a 1990 Honda Prelude. A few months ago it started running the battery down while it's just sitting park-- overnight or in the 10 hours my husband is at work. We bought a new battery, still had the problem. Had the battery checked and replaced due to a bad cell. Still having the problem. If we undo the positive battery cable while it sits, then there is no problem. The FASTEN SEATBELT and DOOR AJAR lights stay on all the time the car is running so we are wondering if there is a short there. Today someone suggested that the voltage regulator might be the problem.

Can anyone tell me what the problem might be and how to find it?

Those lights should be off so that's where to look. For now disconnect neg instead of pos of battery as it's safer, Good luck,

How do you find the wire to those "idiot" lights to disconnect it? We don't really need them since we can obviously tell that our door is closed and seatbelt is fastened-- which it doesn't seem to be able to tell!!
