67 twin turbo dart

Cool.... those batteries like to be AMPed up to around 40 amp for about 30 min. or so.. Kind of gets there hart started again... We use the Jump-N-Carry 660 on most of our jump start stuff.. We use a boat load of Odyssey Extreme Series. Once we get them about 6 volts then we can use a Smart Charger to top them off.
Just food for thought...
Prime away and let it sing !!!! Cheers
