2002 Ford Ranger electrical system problems

Consumer was driving to the store which took about 3 minutes. On the return trip home he began smelling smoke. Then consumer began to see the smoke coming out from under the hood. Consumer opened the hood, and could see the engine engulfed in flames. Consumer contacted the fire department. The fire was out, but smoke continued from under the hood. The fire marshal said that it was an electrical fire. Vehicle is currently under warranty. The dealer did not want to look at the vehicle.

I have learned of this "auto rev limiter" function on my 2002 ford ranger pickup. I noticed this when clearing some cleaning fluid form the intake of the engine. It limited the engine to 3500 RPM were it oscillated. I have heard of other instances of a governor set at 85 MPH on this truck. I feel this is un-necessary for ford to install this and not mention it in the owners manual. If it is mentions I do not see it. I feel this proposes a risk factor in driving or passing when a little extra speed may be needed.
