Possible Battery Drain

[Fireman40]

I think some were some how I have a battery drain. When i leave my truck sit for a few days the batteries get low. I can tell right off the bat when it turns over. I have been carefull to turn off all of my gadets and things like that. I just bought may batteries (deka) 2 januarys ago. I took them to the place a got them and they stated they were a little low on charge. I charged them up and took them back to be tested again. they said they were both fully charged and the alternator was working great. Any ideas on how to test if I have a battery drain somewere in the truck

Easiest way I have found is to take a meter and put one lead on the negative post and the other on the negative cable. shouldn't have very much voltage present only like 0.3

I'm in the same boat with you on the battery drain..... If I leave the truck sitting for more than a week the batteries are dead. Batteries and alternator have also been tested and they are good to go no problems. So I heard about the Priority Start systems which I'm looking into now until I have time to find this drain.

Thanks

Ok I think I finally found the issue with my battery problem. I finally got a round to doing a amp draw test and found that my truck was pulling anyware form .95 to 1 amp with the igntion off and everything else off. I found that my stock radio was pulling about .85 amps. I assume this is way to much. I was told that anything under.25 is ok. So now i guess i need to find a new radio. Or does anybody know how to find or how to correct the problem with the stock radio
