Hello all,<br /><br />I have a Mercury 210 Sailmaster, 1989 (I think) which is the same engine as the 9.9 (hmm...I think). Anyway, no spark to either plugs.<br /><br />1. kill switches have been removed from the circuit<br />2. all wires from the stator, trigger, and switchbox have been cleaned and visually checked<br />3. engine was working fine two weeks ago - it just suddenly stopped sparking.<br /><br />Using a digital voltmeter connected across the two leads of the trigger; and then the stator, there is voltage variation when the engine is cranked by hand (pretty hard to see how much, using a digital voltmeter and my imprecise yanking on the cord).<br /><br />Any idea what to do next ? I'm stumped on how to test the switchbox and how to 'properly' test either the trigger or the stator.<br /><br />Any help appreciated.<br /><br />Rich
