I have a Lazer Z that has run great for 5 years. Yesterday it wouldnt start just clicking sound when the key is turned. I checked all safety switches and couldnt find any issues. Today I jumped the two bolts on the starter solenoid and the starter spins but the engine doesnt turn over. Is there an obvious fix or next step to check?

Sounds like the starter isnt engaging. I replaced mine a couple weeks ago and its dead simple. I think it was just one bolt...maybe 2, and the starter drops right out. You might try jumping 12V straight to the starter and see what happens. If it just spins freely the either the teeth on the starter are shot or the gear isnt popping up.

when i jump across the two big bolts which are 12V and ground, I hear it spinning but not engaging the starter. Does that mean the little piggyback solenoid is bad or the starter itself?

I did some more testing and the yellow wire that goes to the small terminal on the starter solenoid doesnt have power at any key position. What is responsible to power this wire?

Check out schematics pages 49 & 50. http://www.exmark.com/pdfs/4500-264.pdf

When posting in the future post year, model & serial numbers, engine manufacturer as well as all numbers from engine, thanks.

I was thinking of the relay as well. Should I just replace it?

No, I would check relay with multimeter. Look at sears, etc. online and purchase an inexpensive multimeter, instructions included, and check relay. This tool will serve you well for years to come verses just changing out parts.
Multimeter from Sears.com

I just wanted to say thanks. I had this exact issue with mine this week and thought it might be the starter. Luckily I still have the manuals and was able to track the problem back to the PTO switch. It is interesting to learn that the starter won’t engage, but just spins in this situation If you jump the solenoid. Nice, but annoying safety feature.
