Now power to engine/lights/horn battery is good

glad to here you found out what the problem was. i had a car in high school that developed a short in the starter field windings i found the shorted spot and put a piece of circuit board under it so it would not short out against the case and it worked for as long as i had the car. i have always liked figuring out electrical problems its usually a process of elimination to the source. time to enjoy the rest of the camping season.
