I really don't trust any of the chain store china built starters. It's a roll of the dice that you get a good one.
I only recommend the factory Nippondenso starter from Mopar or get one from Denso Direct. I have had a junkyard starter on my Savoy for over 10 years and it works perfect for $30.00 plus $16.00 for some new contacts.
I agree with Doug about checking voltage drop at the cable twocents
