I recently had a problem with my truck not charging the battery and got a duralast gold w/1000 cca and accidently hooked it up backwards for a min and then the truck wouldnt charge the batteryso i replaced the alternater and now it still wont charge it......help!
Hook a test lit at the alt big wire this wire must be hot all times and most of the times is protected with a fusible link prone to burn when hooked backward
SOURCE: not staying charged
what you need to do is disconnect you negitive battery cable and have a test light to connect the circuit. now if you have a drain on your battery the light should be lit.
now with your light lit you need to start to remove fuses and find the circuit that is the problem.
let me know what you find
SOURCE: Battery hooked up backwards
need to have it tested to see if there is a diode in that system they pluginto the fuse panel under thee hood like a fuse but it says diode on top? also have wiring tested at alt make sure you have 12.6 volts at big wire on alt? hope this helps
SOURCE: 2003 Ford Focus battery light is on, but alternator appears good
Disconnect battery ground for 30 seconds & reconnect. Light should be out unless you have deeper diagnostic problem. Charging system good Battery good. This action should reset trouble light. Good luck!

old cars use a fuse link wich looks like a small bump on the wire but chek 4 power first at back of the alternator
