[QUOTE="boatlose, post: 467616, member: 23511"] My E25TEESB has suddenly stopped sparking on both coils. I believe this year motor has an Under Flywheel Ignition setup which Evinrude only had for a few years. I have my spark gap tester hooked up without plugs in. Sometimes on the first crank I'll see one faint spark jump across, but usually nothing. I was suspecting a faulty kill switch. I disconnected the black/yellow wire plug to try to rule it out, same issue. I put one DMM lead on the charge coil side of the now disconnected black/yellow plug and the other lead to ground (bolt on thermostat housing). This reads about 20M ohms. Is this normal? Would you suspect a short to ground or faulty charge coil? I'm lost :LOL2: Thanks! (Edit: Sorry if this should of been in the electrical forum) [/QUOTE]
