Onan P-Series Ignition Module Replacement [Photos]

I am tackling this same issue next month with my 1992 416-8 Wheel Horse. I found this part on Jack's Small Engines:

I am personally not thrilled with Jack's small engines. I ordered a hydrostatic transmission from them for my 54" Cub Cadet and it barely lasted a year and 30 hours. They would not make it up so I have a 2009 Cub Cadet with a great Kohler engine but a shot hydrogear drive that I paid $579 for.

I bought a new module because after installing a new coil that I knew was bad my 1988 518H still had no spark. It now looks to me like the module in my tractor is upside down, how can that be? Looking at the pictures here mine is definitely facing "down" . How did it run in the first place like that? I will turn the module over in the morning and hope to get spark. Frustrating several months, replaced coil and module and still no spark, perhaps it will start. Also took a picture of my old coil wiring before I took it off and that is different then what I see here, again, how did it run previously like that? A mystery for sure.

I would like a photo of that before you change it.

Will take one tomorrow after I finish the brake job on wife’s car. 
Hope I am able to post pics on this site. I need that url link to photo which doesn’t always work for me. Maybe  I’ll get lucky and tractor will fire up!!

After turning ignition module 180* I am happy to report I have spark. It seems the timing may be off a little because it still not starting, fuel is there and it backfired a couple times plus it pushes out the carb also. The more serious issue is the new coil seems to get hot which is a big deal because that was ( I thought ) my original problem, the old coil was partially deformed from excessive heat and it was the first thing I replaced. Could the voltage regulator be a problem causing this? Down the rabbit hole I go... glad that some of you will follow me, thanks.

Here is a brief description, come back and ask questions as needed.

 

Remove the blower housing, then the flywheel.  The flywheel can be difficult without the proper puller, one can be made from a piece of steel with 4 holes to match the holes in the flywheel, and then add a hole in the center with 1/2" threads.  Loosen the center flywheel bolt two turns and then apply the puller.

I have mine installed on the Onan 24HP. It  came with Points. So I had to change to timing cover to mount the module. Where does the white wire from the points go?? I see the black wire from the condenser goes on the positive of the coil!!

 

Thanks RW

Since you eliminated the points the wire can also be eliminated.  With the conversion to electronic ignition, the condenser and the coil may be of the wrong values and not work correctly or fail early.

This is the kit I have for the conversion, you said I should eliminate the white wire for the point so where  does the new condenser connect to the positive side of the coil??

 

Thanks RW

Use the terminal that is right next to the + sign.
