Lost Spark on my Evinrude with disabled VRO. On three separate occasions I’ve been able to return to spark. Swapped out the burnt fuse which I thought would have been the obvious fix only for me to lose spark again shortly after running the engine only the fuse was not burnt out this time. Changed the stator, nothing. Checked short to grounds and repaired some goofy wiring done by the VRO disabler. Spark returned, only to go away after trailering boat. Something is getting jostled around it seems. Grounds clean, coils have been tested and are good. Tried putting my CDI in my friends same motor and had spark. Removed ignition plug to isolate problem to motor. Any help? I’m pretty well stumped now. I do not have a DVA adapter

Charge the battery.----Load test the battery.-----Take starter apart for inspection / cleaning / ohm test on armature.----Little effort and no $$ spent do this.

Will give it a whirl thanks. Any idea of expected ohms reading on the armature?

Should read infinity from commutator to the shaft on a digital meter.

Black/yellow wire is ign killer. If it is grounded anywhere, it will kill the spark. I suspect it has rubbed thru the insulation somewhere.

Disconnect the ign killer wire at the powerpack, and see if you have good, permanent spark. Be prepared to kill motor with choke during this test.

If so, trace killer wire and find where it is been bared. On my '89 Johnny, I found melted wires where the boat harness plugged into the motor harness. I would start there.

Reading the post, poster's model number indicates a "tiller motor" not sure if above info would be correct.

T equals trim and tilt electric start....TE means tiller/electric but I've seen different things on that.

If I'm wrong I'm wrong....you know the jist....

4th of July cannon worked great tonight, happy birthday to the good old US of A.

Ended up buying a DVA and finding a bad timer base. Replaced it and now have spark on all three cylinders. Do I need to do the link and sync following replacement? Feels pointless since all I did was remove and plug in the new. Let me know

Yes you will need to check max timing as the castings can be off and advance/retard max °
