Re: 1970 EVINRUDE 60ESL/ WEAK SPARK/ EVERYONE IS STUMPED!
Joe D -<br /><br />That's a 1970, right? Ok, it's a battery-driven CD ignition. It's totally powered by the battery, and the flywheel has nothing to do with it. All the flywheel and stator do is charge the battery. If the battery is fully charged, it'll run with the stator removed (until the battery drains down). <br /><br />It's also points-triggered. There is no timing sensor under the flywheel (other than the points). <br /><br />All this is based on it being a 1970-71 60hp. If it's 1972 or newer 65hp triple, it's a completely different system.<br /><br />My main suspect would be the points or the coil. If the starter's spinning fast at all, the battery's got plenty of kick in it for that ignition to work. You can check the ignition by finding the thin wire that leads from the powerpack under the flywheel to the points. Disconnect this lead. Also find the fat wire that leads from the coil, under the flywheel. Disconnect this (it's screwed into the connection under the flywheel, so you need to twist it, not just yank on it), and tape it somewhere so it's end is grounded. OK, turn the ignition ON, and momentarily ground the thin wire. Each time you ground it, you should get a good spark where the fat wire meets ground. That spark should jump a 7/16" air gap (hold the fat wire with a good insulator, or it's give you a healthy jolt). If it jumps 7/16", you're powerpack and coil are OK, and your suspects are points or distributor (under the flywheel). If not, coil or powerpack.
