2001 chevy silverado looses all power and stalls, battery light has been on but has been tested along with alternator and tested good. At first, we would jump it and would get 20-30min then die again. All...
Make sure that all the connectors are good...to the battery, mainly to the alternator. Taht should be done with a 12 volt test light at the alternator terminal. The light should be as brillant on both sides of the terminal at the time of the test...with vehicle running. If this test out ok; you will have to start disconnecting fuses one at a time until you find the source that is draining the battery. This can be done by disconnecting the battery and gently touching the cable back on the battery terminal...make sure that all doors are closed so no door lights are on including hood lights that you can disconnect while doing this test. You are looking for spark at the battery terminal. Now, if you have spark; you go to the fuse box and start disconnecting a fuse and going back to the battery and repeat the touch method. If you get a spark, that of course, isn't the fuse that is troubling you, so you replace that one and go to another one until the spark stops at the battery terminal. Once, you have alliminated the fuse at fault, you will now have to look in your owner's manual to see what devices that this fuse supports. Then start unplugging these devices one at a time until there is no spark or very little spark remaining at the battery. This may be too great of a taste for a beginner and may need an tech to do the work, but you can relay this information forward to whomever does the testing. Keep in mind that while unplugging the fuses that the radio stations and clock will need to be reset if you unplug them. This proceedure isn't a hard one, but takes time and care...good luck.
