Re: 1989 Evinrude VRO40hp cranks but won't fire
KMNII.... Disconnect the main red electrical plug at the engine. Remove the spark plugs. Rig a spark tester, something to check the spark. The usual test gap would be 7/16". Crank the engine using a samll jumper between the battery side of the starter solenoid and the small 3/8" hex nut terminal (not the ground terminal).<br /><br />If you now have ignition, there's a short in the instrument wiring harness somewhere. If still no ignition (spark), remove the black/yellow wire that's connected to the powerpack, and crank & check again.<br /><br />If you now have spark, there's a short in the engine wiring harness. If still no spark, the usual culprit is a faulty powerpack.
