NO SPARK NO Nothing!

1981 Kolher 12 hp engine in a JD 212 rider. Complete engine rebuild from rods to rings, to gaskets and gas tank. After the reinstall of the motor into the tight (I mean very tight) engine cradle, and all the wires and what not, I have no spark but yet,
the engine cranks and I have power to most (lights and meter) systems. The saftey swithes are OK, new coil, new soilonoid, new spark plug wire, new condenser, gap is adjusted on the points, .......What else can there be???

Help ME Please...

Are you sure you reconnected all the wires correctly? While putting the engine back into that tight spot, did you happen to break or short out a wire?

Hello smalltractor!

Check for pinched wires as mentioned, and if no problem found, disconnect the kill wire from the points or coil. See if you have spark then. If not, double check your wiring, components and settings. Does the engine have an armature/coil, or a standard automotive type coil?

Hello: smalltractor

I agree with both prior replies. You will definitely need to recheck each wire, each connection and each electrical componet. Besure each is connected correctly, be aware of polarity and do not forget to check the connections at the starter key switch, if one is present.

Chances are good one of the safety switches is either opened or closed when it is not suppose to be. Use a continuity checking device or ohm meter to verify the findings.

Note the results of the findings and post them back in this forum and to this original question. In doing so, the professionals can assist you further in diagnosing the possible problem and provide the corrective method to resolve the problem.

Once you have completed the above process and those provided by the other mod and member, post them back. Check back on your topic several times over the next several days for additional replies.
