But luckily, with the help of the Internet, I was able to remove my old alternator and install a brand new one. It took about an hour after I had to walk inside several times to buy tools. The repair shop charged my battery enough to make it across the street to Lowe’s and I changed the part out there. Now, for only $137 (vs the $400 wanted by the repair shop) I ended up with a new alternator, a tow, a diagnostic, and a whole tool kit plus some wrenches. I say I made out like a bandit, and all it took was a little research, elbow grease, and a sunburn.
