1992 40 evinrude has no spark either cylinder. One day it ran fine next day nothing. Fuse in motor area is good & I checked all the connections, making sure they are tight. Where should I look first power pack, coils, keyswitch? I bought a manual & have someone that can possibily use a voltmeter. Motor is on a pontoon boat at my cabin won't be going there for 2 weeks. Thanks Dan.
