Hello,
My wrinkly old Ranger 53k miles (2002 V6 4.0 SuperCab) had a problem new to me a couple weeks ago. When I was driving, my lights dimmed and my truck slowed. I noticed the red battery gauge light was on, and the needle was almost buried all the way into the negative side.
This all lasted just a few seconds. Because everything recovered, I didn't give it attention.
Last night, I noticed the red battery light was on again, but this time the needle on the gauge was pointing up towards the + side.
My un-informed guess is a voltage regulator needs replacing. Any ideas on this? Does this sound like the problem? Can I fix it my self?
Thanks Bill
