Hello all, I have a 1991 chevy blazer. I recently got the engine rebuilt and since then the battery will be totally drained if i let it sit there and dont run it fo a day or two. I've had the alternator tested and is OK, the battery is brand new also. Is there any way to test for an electrical leak? Or is there something I can check for that im missing? Any help at all would be appreciated.

 

Plenty of ways to test for a amp draw. On an older vehicle, it has to be something pretty simple. Use a multimeter set to the amp scale. Remove the fuses one at a time and put the leads from the multimeter into the terminals in the fuse box. Record the values for each fuse. You should find the source of your draw that way. If you don't, then it is something that isn't powered through the fuse box.
