I'm going to throw this in here FWIW, ok?
Don't buy an alternator (if you need one) from Pep Boys. Back in 1994, the alternator in my 86 Civic CRX went. I bought a new one (rebuilt...they are ALL rebuilt unless you buy one from the dealer for 100% more money) from Pep Boys.
I installed it. I've installed tens of alts/starters/carbs/etc before. One big wire that goes to the battery and one molex connector that only goes on one way. An Angel-Dusted Monkey could do it.
Started it right up. Went for a drive. Going down the highway, my dash lights started glowing brighter and brighter and brighter...somethings very wrong. As I pulled over to the shoulder...*POP-POP-BOOM-POP-POP* and the car died.
What happened is that the regulator in the alt failed and overcharged/overvolted my entire electrical system.
Blew EVERY SINGLE BULB in the car. Every last one down to the idiot lights in the dash. It also fried my ECU and melted most of the wiring harness. $1,300 in damage.
Pep boys tested the alt and found it to be "just fine...nothing wrong with it." But then they refused to send the alternator back to me, even if I paid for shipping. Sound suspicious? You bet your ass it does.
I had a local automotive electrical specialty shop (they fixed the car) write a letter for me stating that the alternator most definitely was the cause of this major meltdown.
Pep boys refused to accept responsibility of any kind. After many very angry phone calls, I got a call back from their regional manager. He told me "we'll refund your money for the alternator, but not a penny more...get a lawyer if you want."
I had to borrow the money to get the car fixed to begin with; I had no money for a lawyer.
Since 1994, I have not purchased a single thing from Pep Boys. Not even a smelly tree for the mirror. There is a Pep Boys exactly 6 blocks from my house. I drive right past it for another mile or so to go to Auto Zone.
That's my story. You do what you want. Caveat Emptor.
