Have been wrestling with my bag of electronic parts to convert a wheelhorse 10HP Raider engine from a solid state coil that ran off the magneto to a solid state that uses a coil, module, an an automotive type ignition switch.
Here are some things I am puzzled about.

The new ignition switch does not ground out when turned off. I thought this was necessary to shut off the engine.

The module has two terminals for imput from the old ssi coil that was modified to work off a internal transistor. I believe the old ssi coil is internally grounded. Does that mean I only need to attach one wire to the module as long is it is also grounded?

Do I need a resister to cut down voltage from 12v to 9v going into the new automotive coil?

How can I be sure that the voltage from the battery is not dirrected into the ssi coil. I need to know this before I attach the battery to the switch.

My ignition switch has the following letters s,b,i,a and r

whats going to triger the on and of of the spark ??
The spark is triggered by the modified solid state ignition coil that was modified with a transistor after the original burned out. This sends voltage from the battery to an automotive type coil where it is held until the flywheel comes by the magnitic trigger that signals the transistor to discharge the coil to the spark plug.
 
I'm not sure about navigating the archives & stuff on here but if you're talking about a Tecumseh I seen a link on here or somewhere that a guy explains the whole switch-over procedure in pretty good detail . Maybe someone on here will know where to find it .

I have been working on my raider 10 since this winter to replace the ignition coil and get it running again. Finally got it going a couple of days ago, cut the lawn with it today. Want to pass on a few things I learned in the process.

check out the forums and use google to find as much basic information as you can so that you have an understanding of how things work and what you must be sure of being right before you send the juice through the wires.

buy a spark tester that attaches to the plug to give you visual proof of spark. Do not ground the plug to the motor which can burn out your new ignition.

Work on the wiring with your battery out of the machine and only attache the battery when ready for lift off.
