my truck has been acting kind of funny for the past 2 days. my RPM's are not as high as they usuaully are and my battery volt is 14.2 watts and when i hit the brakes and turn it drops down to 12.5. when that happens my battery light turns on, steering wheel tightens up and truck slows down. the only way to get my truck running after that is turning it off and starting it up again. anybody know what might be wrong or had the same problems? please help

 

Wow that's a weird one. How old is your battery and have you checked out all the connections thoroughly?

 

x2 on checking your battery cables and make sure they are tight and clean. You can also goto an autozone or other auto place and ask them to test your battery.

 

I would also check your altenator. When you break and slowdown it maybe having problems keeping your voltage up. Typical of worn out windings. I would take it in and have it bench tested. And also agree take the time and clean all battery connections. But sounds like failing altenator.
