Question about Ford Ranger
The voltage gauge drops when I rev up the motor but goes back to normal when at idle speed. I disconnected the battery terminal from the battery and the engine continued to run till I increased the engines rpms and the truck died. At idle everything seems normal but only have an issue when at cruising speeds. I put a new belt thinking it may be slipping during this cold weather but still having the same troubles.

Have your alternator checked at your local alternator/battery store.. it sounds like a diode has gone bad...

This is what we do in the shop, use a 1/2" wooden dowel (about 24" long) and touch anything that spins, this includes the water pump, the belt pulleys, the P/S pump, the Alternator etc. while holding the dowel up against your ear (eng idleing), this will amplify the noise and u can isolate what component is the problem, the most common is the power steering pump

likely what you are seeing is the first signs of slipping. If permitted to continue, likely it will get worse and you will then lose a bit of speed when it happens. In warmer weather the trans runs a bit hotter and will react to that. If you cannot hear the revs increasing but the tach says they are, it's also possible that for some reason the tach isn't reading correctly. Any good tech should be able to tell the difference. Problem I have is that I'm here and can't drive it to give you a "definite" on either.The only way to verify this yourself would be to attach an external tach to the engine and compare the rpms of the one in your dash to that one.
