2004 Lincoln Aviator
Battery dies when rear gate is opened for just a few minutes. Battery tests
good and no other problems except when rear gate is opened to load or
unload, even for just a few minutes. Jump it with cables and all is fine again.
Did they load test the battery? it should last a lot longer than that, Are the battery terminals clean and bright, none of that black corrosion.
Batteries have been tested and checked and are all OK. Batteries actually were replaced when this began happening to make sure they were OK. Nothing else drains the battery but the back gate (Hatch). It can only be open for a few minutes and the battery dies. Would love to know how to correct this.
I have looked over the wiring diagrams for the rear hatch and I see nothing that has that heavy of a load. This one looks like it is time for the pros to take over. they are going to have to check the total amperage draw with everything related to the rear hatch while it is opened, so it will have to be hooked up to code saver equipment and a charger to maintain power while the tests are being performed. So take it to a shop you trust and see what they find.
Thank you for your help. Taking the car in for diagnosis to see what's going on.
Found that the light on the rear hatch was extremely hot as soon as the hatch was opened. Removed the light and now the battery doesn't die when the hatch is opened for any length of time. Don't know what the wiring problem is, but the battery problem has been solved and I'm ok with that.
Wow, I have never heard of a lamp killing a battery that quick, even headlights won't do that. But if you have removed it and it no longer kills the battery then you have found your excessive current draw, that ones a real stumper. Thanks for letting us know.
