Draw on battery?

[ydopen]

2 years ago the parking light/dash light was putting a draw on the battery. I pulled the tail lights and the front markers out. Wiggled them and it has been fine for 2 years. Now im getting a draw on the battery from somewhere else

how much of a draw are you getting it would help to know that figure

Do a YouTube search for "parasitic draw test" which describes how to find which circuit(s) has the draw.

Thanks fellas. I can put a meter on it and it falls a number about every 5 seconds.

what do you mean by "falls a number about every 5 seconds"
what is the amp reading?

Oh. Hmm. Im new to this. I mean after I jump it off and let it run 5-10 min. I can put the meter on it and its on say 12.70 then after 5-10 seconds it falls to 12.69

are those figures battery voltage

Does your meter measure current? Or better yet, what make and model number is it?
Bedrck46 and I will walk you through electrical 101.

I guess? Its over 14 when running but after cut off it starts dropping. I havent been driving it everyday. It mite be a slow enuff draw to be ok. But after sitting for a week it will zap a new battery

First step is to check for battery problems. Disconnect one battery cable and take voltage readings over an hour on the battery posts. You shouldn't see any substantial drop in voltage.

You need to understand how to hook up your meter to get an amp draw reading. And also do what stamp11127 has recommended

A normal draw is in milliamps (.001amp). There are 1000 milliamps in one amp so anything past a few milliamps would be of concern. The radio, memory seats and pcm have a slight draw and should be the only electronics that draw.
