Thanks Guys.
I already returned the first battery after a couple of weeks. Even though it tested good at the battery store they gave me a new one that has 650 CC amps. still turns slow.
I was going to go to the starter next. I tried one place today but they couldn't test 6volts. I'll check around Monday. Yep, my cables are really 0 gauge.
Where do you get a 6V Optima and how much do they cost?
