Hello, I am new to the forums and was looking for some guidance with a few electrical problems in my '02 Ranger.

#1. The Negative Battery Cable. My battery terminals were always bad in my Ranger, very difficult to remove, and very corroded. It finally got to the point where I couldn't get them off at all. My ranger sat for a few months and the battery ended up dying totally, unable to be charged, and I couldn't get the terminals off, so I had to cut the cables. I cut the cables as close to the terminals as I could, but the negative is very short and if I put a new terminal on it, it would not reach the battery. I wanted to know what gauge the battery wires are, as I would like to splice them, and put on a different style of terminals.

#2. Flickering Gauge Lights. About a year ago, my fuel and volt gauges (all the way on the left of my cluster) started flickering. None of the other interior or exterior of the lights flicker, even none of the other gauges. I was thinking this could be something with a voltage regulator somewhere? That is a total guess.

#3. Speedo Reading while idling in Park. Before my ranger got parked, I was idling it after it sat for sometime. I noticed that the speedometer was reading around 10mph quite erratically at idle. If I increased the RPMs in park, it would read up to 20 mph but again quite erratic. I was guessing this might be the speed sensor?

Any and all help is greatly appreciated.
