Looking for some tips on where to start looking/troubleshooting. My neighborhood streets flooded up to our doorstep about a week ago (15 minutes from New Orleans) and my car was backed into driveway. I looked in her after the water went down and the inside was dry, It got up to the rockers. Anyway I went to put it back in garage and it?s doing nothing. Battery is charged, terminals tight and corrosion free. Headlights, Dome lights, under hood light, ignition nothing coming on. I took terminals off double checked charge and even put charger on battery when it was in the car nothing. Any tips help. Thanks, Randy

 

Check the fusible links at the starter.

 

Check the fuse panel under the steering wheel and see if any blew out. If it did, there might be an exposed wire that got shorted.

 

Plain water is not sufficiently conductive to cause overcurrent (shorting) problems at 12V. However, all the items which may have been underwater are suspect due to contamination. For example, there is frequently a lot of carbon and copper accumulated in a starter motor. If that were to go underwater and the conductive material became suspended in water then was allowed to settle into the bottom of the motor, that could cause shorting problems.

The same phenomenon can occur with other things which went submerged, and this doesn't even consider the silt and contamination carried by flood waters, Get out your meter, your schematic, and galoshes, and start checking from the battery onward.
