Force 50 model 507x7a no ignition wiring harness/ no spark

[larrydb]

I've purchased a used Force 50. It did not come with the ignition harness. I have managed to get it to turn over, but there is no spark. Which other wires on the engine need to be crossed to get a spark? So far I've managed to activate the choke and starter, but I do not know what to do with the blue and white leads that seem to lead to the magneto.

Here is a pic of the wiring. Hope it helps.

The picture helps alot, what I could really use is a list of where the wires go,
like #1 at the top, i beleive is igntion/start, if they are numbered from one down where do the rest go? I am definitley new to this!! In particular #3 and #7 (both from the magneto?) what do I hook them up to to get a spark?

All the wires in the right hand side of the terminal block come directly from the boats wiring harness. From the ignition switch to the motor is what you are dealing with. I take it your harness is not color coded exactly like the engine? When you say the rest, do you mean you have more than in the pics? If you follow the color coding as in the pics you should be fine. Is your ignition exactly like the one in the pic?

Sorry, I forgot you said you don't have a harness :facepalm: I get ahead of myself sometimes. Check out these diagrams they should explain where everything goes. www.maxrules.com-graphics-force-wiring-CHRY35_50_80_84 and www.maxrules.com/graphics/force/wiring/CHRY35_50_80_84.gif

I don't suppose you have a pic of the stator/condensor wiring with the flywheel off. Same motor. your pics were of great use to me to verify the wiring onthe outside of the motor, but not sure about how it is connected at the stator and condensors.

Thanks for your pics.

Give me a few, I will go pull the flywheel and take some pics.

Here is a link to the condensed version of the service manual if you don't have one. Let the page load for several seconds and download to your computer soonest as the link is short lived.
