well got the big 3 done in 0 gauge, brand new optima red top, and a supposed 200 amp alternator. well my voltage is dropping in reverse and a little bit in drive and also when i turn the wheel. im not sure what the problem is with this, but i would like some help big time. oh and its a little worse when my foot is on the brake in drive or reverse. grounds and the power wire for the big 3 are good. it is also bad mostly at night. and ideas???

 

well i believe i found out why my electrical is all screwed up. took my blazer to a trustworthy electrical place in town and they hooked it up to a carbon pile and long behold my alternator is putting out 80 amps at 2000 rpm < def not good that barely enough to run the normal stuff. im so pist off right now and the guy cant fix it till monday. hence you get what you pay for i guess, luckily he's gonna fix it and he's only a town over. he got one more shot at this and then im gonna get my money back.
