This morning I began installation on a Sony cd player. It is going into a manual 1994? ford escort. I took out the old stereo and put in the new, reconnected the battery, turned the ignition to ACC and lo and behold it works. I test everything else in the panel before I put the dash back in. I am about to disconnect the battery terminal to complete installation, and I think let me just make sure the car starts. You guessed it, it doesn't. It doesnt crank, it just kinda clicks. Any idea what the hell I did wrong/how to fix it? On a side note, the battery was pretty old and had a decent amount of acid buildup on the negative terminal. I don't understand why everything electrical works and the car won't start. PLEASE help!

 

If you did the install right, there should be no effect on the car, maybe you blew a fuse to the plugs or something else, try turning the deck off and then starting the car.

 

battery is too low... use a charger and it should start

 

Problem has been fixed...Turns out there was so much corrosion on the battery that it was not a good enough connection. New battery fixed problem, now I only need to get the damn thing back in the dash! Thanks again!
