i bought this pontoon in middle of winter, just started working on it this spring, put the key in and didn’t fit, wrong key, so bought a new switch, not sure if this pontoon had problems or not. just ran a ground wire from ground on switch to the battery ground, tried to shut off and it kept running, so i had to pull apart the big plug and touch the black/yellow prong which is on the motor side of plug and it grounded it just fine shutting it down. just seems like a simple problem, to wires heading to motor for shut off, black/yellow and black(ground), seems like ground is failing in motor, i tested switch also with multi meter for voltage from B and M(ground) getting 12.6 volts with switch off, shouldn’t that tell me good ground?
