Default CC 129 no ignition spark
I will admit up front, if you might note from some of my prior Threads, I was having difficulty with my CC124 and the creeper gear I had installed last year, which I still have not remedied and decided to maybe transfer my rototilling operation to a CC129 Hydro I also have. Last Fall as I put things up for the Winter the 129 started and ran without difficulty.

This Summer as I tried to start the 129 it would not fire. Starter turns easily but no ignition. Cleaned the plug etc. but no go. Tested with spark tester and no spark. Thought it might be the coil or condenser so I took it off the 124 (since I knew it worked) but still no spark.

On advise from a friend I noted no current going to the + lead on the coil. I then went up to the ignition/starter switch thinkingit might be a bad switch but I tested the posts with contunity tester and current circulated properly. I thought the wire from the switch to the coil might have disrupted (being wrapped in a harness, which I did not want to unravel)) but it tested ok on the contunity test also.

Question: why am I not getting power to the coil? What am I leaving out.? New battery etc.

Thank You

Safety switches.

Go to the Tech Library Section on page 5 & D/L the wiring diagram.

Roland, the ignition circuit doesn't run through the safety switches on a 129. You know that....

Are you sure your testing the correct wire? The correct terminal on the switch?

If a wire is broken, or has only one strand connecting it, it will test continuity with a meter. Check everything over again. I have a feeling that you are getting power, you are just making a bad connection when checking. If you truly believe you aren't..... well, run a new wire man.

IF you find you are getting power and it still doesn't run, defer to Lew's post. It is the most likely.

If there is no power to the coil then there is no power to the coil, not much else you can do but chase it back and find out where it stops.

The wire to the POS (+) side of the coil on a 129 comes directly from the "I" terminal on the ignition switch and is "hot" when the key is in the "on" (run) position AND in the "start" position. It gets its power from the "B" terminal on the ignition switch and it gets its power from the neg (-) side of the amp gauge...

Look up the wiring diagram in the tech section and follow your wiring back to find out where the power is and where it stops.

Wasn't thinking fast enough.....I was focused on the "start circuit" verses the ignition circuit.

So do the clutch/PTO safety switches only interrupt the starter circuit but not the ignition circuit?

On a 129...... yes, that is correct.

Dear Mr. Bedell: I can't seem to locate "Tech Library Section" to obtain the wiring schematic you suggest. Could you link it for me in reply?
Thank You

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
