Hi, coil checking is pretty simple and will save you time and unneeded parts replacement. Get the multimeter on the Ohm x 1000 range and get a reading between the terminal feeding the sparkplug and any of the other coil terminals ( aka checking on the secondary winding). If the reading is between 3 and 8, the coil is good. Scoot along and be merry !

Im not getting spark on both cylinders, im getting reading on coils 13-14k I assume im reading it right. Motor ran last time i out it away over 10years ago. Its 74 johnson 9.9. Makes me want to think its something wrong with magneto. I did have a wire chewed by mice thats going to kill switch. I just dont know if im reading OHMs right

@@osilekpl79 I alors stumbled over Amazon coils that read 13K and found them not to be that good on OMC outboards. Most of them were bright green coloured. Those do work fine on those old Lawnboy mowers. My suggestion is to get Sierra coils as they are within specs. Regards !

Well, I appreciate you pointing out the fact that using the impact gun to spin the flywheel can over torque the flywheel not, damage the flywheel and the crank...I also appreciate that you hate butt connectors/splices that same way I do. This system will not tolerate poor connections, especially when they get a bit wet. The key to working on this system is to have the "amphenol pin/socket tools", so those pins and sockets can be removed/reinstalled from those rubber connectors. Expensive tools, but necessary for working on all the OMC outboards from the late 70s through the 90s. It is when techs don't have those essential tools that I see horrible splice jobs. Those crazy looking coils are what the actual OEM replacements would look like also. The difference is that BRP would give you a nice primary lead with its push on connector/ampenol pin on the other side. Neither of those coils is OEM. That crazy slide on terminal that was given to you with the top coil is not going to work out, especially in a moist environment, and you surely wouldn't want to accidentally touch it when the engine is running. I appreciate what you were attempting to do with the powerpack wiring, but that stiff loom probably won't work out, and might hit the flywheel. The coil primaries and stop lead bundle harness needs to be routed back down towards the bottom of the cylinder head so it can end up in the clamp that was originally located in the middle of the coils. The clamp arrangement you have up top probably is not going to work out..This is a compact engine, with little room to spare anywhere, the slightest change in wiring routing will probably end up rubbing on the engine cover or getting tangled in the flywheel... Your technique at the end was spot on for troubleshooting, swapping powerpack primary outputs between coils. Unfortunately, you really need the amphenol tools, or at least amphenol jumper leads to make these swaps easily. The amphenol jumper leads are relatively inexpensive and can be purchased from Stevens Instruments in Illinois. This system is actually pretty simple, and easy to troubleshoot. That extra ground lead on top of the coil is for the stop switch. The stop switch grounds out the pack output, and it should always be removed from the system first when troubleshooting. The best troubleshooting technique for this system is basic tests. Stop switch elimination, grounds using the low scale on the ohm meter, simple resistance readings for the coils, charge and sensor coils. And finally, never forget to check those amphenol connections. That is a nice old 15hp, must be from the fresh water....D

@@fullyhooked1 A charge coil failure is very rare on these engines, unless it got physically damaged from rubbing on the flywheel, or the wiring got damaged from chafing or melted from an overheat...But, it does happen. The charge coil is easy to check with a basic ohm meter, I'm glad you were able to solve the problem... Simple tests are the best with this system, and usually find the problem....D

Found this looking. My old 28 is missing on the bottom cylinder. I have spark just not all the time. Cleaned and regapped points. Same situation. Im not sure if the points are sticking. If the coil is breaking down or if there is too much gap to the flywheel. It ran good 10 years ago prior to storage. I didnt see any mice eaten wires. Checked the plug wire. Doesnt look like its bad anywhere. Wiggled it around. I hate to just throw parts at it. Coils look fine no cracks

Three days ago I worked on a friends evinrude that wasn't getting spark to two of the four cylinders and like so many other boat owners he wanted to replace the coil on the two dead cylinders. I looked at the engine and made sure they were making a good contact by twisting the spark plug wire at the connection of the coil. As usual it fired right up with no problem. People replace parts that are good by not checking the connections. I have often wondered how many good coils have been replaced due to not checking the contact of their wires?
