Well then one of the guys with the scanners or -voltage/ multi meters was mistaken. Some of the guys at parts houses know what they are doing... others not so much. Pulling fuses is not going to solve anything, either your charging system is working or not, an output of 11v means that your alt has failed or about to. 13.09 is what it should be. Up to 14.5. If your battery is 5 or 6 years old then it's likely just that simple. You need a new battery

I havent been using those things not removing the fuses. It hasnt had any issues since but the guy said 13.09 would keep it running but still drain my batt. I bought it in jan. So its still strong. I read that they have a problem with power steering fluid leaking into them and causing failure. I dont want to get stranded but dont have the cash to replace it.so will it be okay to drive on that output?

My LS400 is not running like a V8 should. For the first few years i've had the car it ran great. I use to fool around and drive fast, and when i hit the gas it picked up speed and roared like a V8 should, now it doesn't pick up the speed nor rev up like it used to. What could be the problem? What do i need to fix? 1 Answer
