Last night after messing around with a friend coming back to the dock, I pull off plane and the boat dies. Go to crank - no start. Pulled the cowl and saw the idle timing set screw jam nut came loose, I figured no big deal, fresh plugs and set the timing, I'll be good in the morning.

So today I go out and take a peek, I'm not getting spark at all. I open up the crap manual I bought that has given me no help in the past, and is continuing. I don't have the Johnson/Evinrude tool to check whatever it's asking me to check at the timer base, which I can't understand what it's asking that a multi-meter can't do. Anyway, no spark on any hole. Power at the orange wire on the bus bar while cranking, what are my next steps? I pulled the 4 pin plug to start to check per the manual, but I don't have the correct tool to do this, or if a multi-meter will do it, I don't know the settings it's asking for.

Thanks for the help in advance fellas

BTW

Following tests done making sure the teather is in and the plugs are out to crank.

Purple wire to bus bar key on = 12+V
Two Yellow wires from Stator to bus bar = 12+V
Gray wire at bus bar = 5V while cranking
Two orange wires from stator at bus bar = 5V while cranking

I have no way to check the advance timer base apparently.

Anything to be said out of this info?

I checked everything on here minus the DVA as I don't have the right meter, but it ohm's out okay.

I did unplug the cannon plug and jumped the solenoid, no change. I'm almost wondering if it's not the power pack, but I'm not sure. The yellow wires coming from the stator are showing 12V but the orange ones aren't showing much for volts unless they're not supposed to.

Update, the power wire y/r headed to the power pack is only showing 10.3v while the hot wire at the solenoid shows 12.6v. I have it on a charger as a "just in case" thing and will re-check.

Okay, no change for volts after sitting on the charger for a bit. Thought I'd check the shift switch on the power head. I could not make the continuity change on either plug in, so I tried by-passing it by unplugging the switch and plugging the two plugs into themselves at the power pack - no change. I assume that's the way to bypass the switch? When I checked continuity, I noticed one wire was always open, no change with the gear change, and one was always closed, no change with the gear change. I assume that's how that is or has that failed too?

Man I'm scratching my head on this one.

The Y/R wire from the solenoid to the pack should have 12v to activate the ignition during cranking, remove the terminal at the solenoid and clean it up. Check wire for resistance.

Pulled the kill wire at the pack and tested - no spark

Pulled the yellow wires from the stator - no spark

Will check resistance in the y/r wire after dinner I guess.

Re: '90 200 V6 Looper No Spark

So if I have to have all of 12V on the yellow power wire going to the power pack coming off the solenoid, I check power off the signal post on the solenoid, and I'm only getting 10.3V max off of the post that wire is tied to. Possible bad solenoid? My other question is that it's only getting power while I'd be cranking, is there something that keeps the spark going once fired? Am I barking up the wrong tree?

Yeh you got the right idea, y/r wire provides clean 12v to the PP during cranking, when the starter is released the stator takes over and there should be zero v on the y/r wire when the starter is not cranking.
So that 10v is a problem at the solenoid.
Test the power cable from the battery post to the starter for resistance, then clean the terminals at the solenoid, they get pretty corroded.
Otherwise its in the solenoid.

You may also have other issues with the stator, one thing at a time.

12.6 on the bat side of solenoid, 10.3 on signal side. I guess I should have added that.

There shouldn't be any v drop, its either terminals dirty or internally worn.
Cheap fix either way.:)

Re: '90 200 V6 Looper No Spark

Got my DVA in the mail so I could do some real diag.

Charge and Power coil (Stator) = Pass on V and Pass on Ohm

Trigger = No readings at all on anything = Fail. Ordered my timing base overnight. Gotta get this thing going a week from tomorrow for a river run in Illinois. ;)
