Re: Electrical woes
I would start with checking for burned wires. Check for melted insulation. If it only happens when the peddle is on the floor, It may be shorting a wire. From there, I would go to the charging system since it is directly related to engine speed. Start with the voltage regulator. They go for 12 bucks and are easy to replace, since they are mounted to the firewall with two screws and have one plug. From there, I would go to the alternator. There may be a problem with the rotor or stator and at high RPM's cause problems, but at idle it may not spin fast enough to do anything. Lastly, check sensors on the engine. One could be shorted and that circuit is not activated until the engine is at a certain RPM, under a certain amount of load, or throttle plate is at a certain position. Example: The Throttle Position Sensor is bad and is not activated until you are at Wide Open Throttle.
This is how I start troubleshooting the problem. Good luck, Eric
If it ain't broke, I can probably still fix it.
