Hi All,
Need some expert advise from you guys. I have 1998 Pontiac Grand Prix 3.8L supercharged with 170K kilometers. This car has become a worse nightmare for me. Since March this year it's giving me some electrical trouble which no body is able to understand. Error code P0560 (System voltage malfunction). This is an intermittent problem and my car just stalls and transmission doesn't want to shift the gears. I have to drive in 1 gear only. I changed a couple of alternators in 4 months. Both turned out faulty by overcharging. Changed battery and put the new interstate one. Problem still persists. Can somebody help me in resolving this error. Please help me. Your kind advise will be greatly appreciated. I can't tell you how much trouble i have been going thru both financially and mentally just because of this problem.
