Badboy magnum right at 2 years old. Starter solenoid clicks continuously while turning key to start position but will not turn over. It looks like the starter is turning but not engaging “popping up to turn the flywheel to start the mower”. Replaced the started solenoid. Still nothing. Battery has atleast 12.5 volts. Battery negative to battery side of the solenoid has 12.5vdc +- the other side of the solenoid with the key turned only has around 4vdc. Less than that when checked at the starter. Pulled off instrument cluster cover and checked switch for continuity and has it there. Checked between S and the white wire on starter solenoid and it has very little voltage. I’m lost on this. Any help would be much appreciated.
