1997 pete 379 battery draw

Does it have a qualcom? Sometimes they will not go to sleep and run a battery down.

 

How are you testing for the draw?

 

Not really a valid test. Although the test light should not have lit up. The ecms and radio all take power all the time. You need to check with a dvom that can do amps anything over .5 amps is trouble. Make sure all lights are off and doors are closed or you will be changing the breaker in your meter. If your drawing over .5 amps go to the fuse panel and pull a 1 fuse at a time till you lose your big draw. That will tell you what circut to look at. Most likely source will be the radio I have also seen cell phone chargers, even with nothing attached to them, cause a draw.

 

what DC meter? clamp meter? I use clamp meter, but every time before use reset current reading.

26 A is too much, it is more then 300 wt, it is more then headlamp power! so something must be really hot.

Pull out fuses one by one till you find a problem.

Try to measure current in different points, in alternator area, near starter

 

You could have a dead cell in one of your batterys and that sucking down the others.
How old are they??
