2006 Kymco MXU250 will pull start on 1st pull. However, when using the starter, it won't hit. Spark is too weak. Changed ignition switch, starter switch, and ECI module. Nothing. Trying to find where voltage is going when using the starter. With battery removed, and key on, I'm showing a near short (8 ohms) between positive battery cable and ground. Is this normal? Would appreciate any help. Has been down a year, and two different mechanics have been unable to solve.
