[QUOTE="faiz23, post: 5714227, member: 607241"] Awesome guys thanks for the quick posts, i have some answers to your questions the alternator is a 130amp, i went to rockauto and some other websites and checked a 2000 merc cougar v6 would have the 130 amp versus the 90 amp for the 4 banger. i have the stinger upfront which i got from bumpin buick and it looked pretty new overall and rested at 12.8ish when i got it, i threw it onto a cascade power supply 75 amp smart power supply overnight and then used it in the car couple days there after. [COLOR=Red]"I'd recommend adding a 0/1 ga ground from the engine block directly to the chassis.
