Re: 72 650 3 cylinder merc, no spark
Mattbe,<br /><br />Start with the usual things. Is 12 volts being feed to the switch box, has the 'mercury switch' gone faulty, are there any broken wires?<br /><br />If you have a testlight or voltmeter check the following on the switch box.<br /><br />1) 12 Volts on the red terminal at all times.<br />2) 12 volts on the white terminal with the key in the "ON" position<br />3) 12 volts on the brown terminal with the key in the "ON" position. If low or nothing on this one the mercury tilt switch is faulty.<br /><br />Chris............
