...noticed that my amp gauge was around 9-10 not at 14 (normal) ...


I'm assuming that you mean your volt gauge (voltmeter), not your amp gauge (ammeter).

Spend the money and just replace your battery cables, as well as the positive cable going to the starter. I'd also get the battery checked with a load tester, not just a voltmeter.
