I noticed today that my voltage in the omni would climb to the very upper limit of normal and stay there for a while. I also noticed what I thought to be my PS pump belt squeeling like crazy. I cut off the PS belt tonight and went for a drive. All was well until my volts got really high again while I was giving it a decent dose of throttle. My headlights got very bright very quickly, and then all was black. The squeeling came back in a big way. I was able to drive it home with the volt gauge at about 17. The turn signals still work as does everything but the headlights, so I am thankful for that.
I had checked the acessory drive belt before taking off, and it seems fine.
What should I check first? I knew I got this car going to easily this year.
