What is causing my engine to turn over slow?
Asked by Kasey Jan 31, 2023 at 05:50 AM about the 2007 Chrysler Town & Country FWD
Question type: Maintenance & Repair
First part of December I had the alternator remanufactured. At the same time I
purchased a new battery. I also replaced the starter as it started to spin the
motor over slower and slower about a week later. The new starter still turns the
engine over slow and now a month later I've got a low system voltage warning.
Any ideas?

Alternator failing, voltage loss in main power and grounding cables, ECM charging circuit inoperative, bad battery. Just cause something is new doesn’t mean it’s good.
There are a lot of interpretations of the word, remanufactured. I would first suspect that the starter is the problem, it's faulty and causing an excess electrical drain when you start the car. The fact that it got worse over time seems to confirm this suspicion. When the starter has a heavy draw, it drains the battery more. That could damage even a good battery or cause it to take much longer to properly charge, which could damage the alternator.

All electrical connections should be clean and tight , The starter/batt cable should be in good condition but it's probably the crappy starter , Try rock auto/AC Delco or dealership for an OEM part . I don't buy from auto zoo or nipa
On an 07 model you could very well have a dirty or corroded electrical connection creating high resistance in the starting and or charging circuits. Check all your connections, load test the battery, bench test the starter and alternator as well. Remanufactured units are very often defective right out of the box. One last thing, make sure you have the correct battery with the correct cold cranking amps (CCA) for the vehicle. It's also not uncommon to be sold the wrong battery by the 18 year old counter person at your local auto parts store! Hope that helps! Jim
New "REMANUFACTURED" does not mean its good, slow spinning starters is a good indicator that the winding in the motor has a high draw short, the little Chinese guy that built it gets paid for quantity not quality. Start w the basics check conections at both ends at starter and battery and on ground to vehicle and battery. White powdery "dust" on trans connection is very common in salt climates and in states that salt roads corrosion is a BIG problem. If connections are clean and check out. I would look to starter. Stay away from durafail and twat o zone one out of four starters will fail just ouside warranty or w in 6 months. My personal exp as an ASE 30+ years exp.
