i know this has been covered over and over but id like a second opinion before i spend 180 bucks on a new starter. So it cranks slow, had an old battery in it so i replaced it with a diehard gold. didnt fix the prob (the terminals are clean and tight). Put a meter on the batt and it reads 12.3v. while running its 13.6v. while cranking its 9.XXv. lights are nice and bright... never dim, but it still cranks slow, almost to the point where it sounds like it will stop turning over. i bought the jeep used so i dont know much of its history. but i do know its been replaced before (has an AC Delco starter in it). What are some other things i can check before i make the jump and buy a new one? thanks jeepforum!
I'm with PCJona - Sounds like a starter. Pull it and have the auto parts guys test it if you want to make sure. Only other thing I can think of is the taps on the starter are a bit loose, but that is probably unlikely.
3. Did you buy the correct battery or the cheap it will fit kind.
Had a simalar problem with my friends car, he bought a brand new battery but only got a 500 cca battery when he needed a 800 cca battery. car would still start but cranked really slow. We checked everything else before i noticed it was the crappy battery he had. Also, just cause its new doesnt mean its good. I got a brand new battery one time for my bike. It was DOA when i got it. Didnt know till i put it in the bike, which would not start still, and took it to a shop. And you can have 12v's on a battery but get no amperage. Just had that problem with another car i was working on the other day. My advice remove the battery and starter and take them in for testing, replace as necessary.
That volt to amp discussion is valid and even new batteries may still need a charge to attain their rated capacity, but he has no dimming, so I'm in the weak starter camp too.
