[QUOTE="bmk6795, post: 8059103, member: 642753"] Ok long story short, when i accelerate the voltage drops to about 12.5 volts. This doesnt happen all the time however it happens often. If im on the interstate and the rpms are 3k+ the voltage stays at 14.4 volts. When im crusing around town and i let my foot off the gas the voltage goes back up, but as soon as i hit the gas again the voltage drops. This is all without any music on. Any ideas what this could be? Ive got the stock battery and alt with the big 3 done. Ive checked every ground for the big 3 and for the amps and they are all good. Ive tried a different battery that i know is good and that didnt work. Tightened up the alt belt because i thought that was it and that didnt fix it. Ive had the batt and alt tested at parts stores and the alt came back ok. I dont think its the pcm just because it doesnt do this every single time i drive. Any ideas as to what could be going on?
