Small Engines (Lawn Mowers, etc.)/murray rider


after new battery and solenoid it wont even do anything and new spark please  please help model 40508x92 12.5 horse 42 inch cut it wont even click over

Safety or interlock switch problem?

How many small wires does the solenoid have, 1 or 2?

If you have only 1 small wire, take a clip lead and connect one end to the solenoid small wire post and then touch the other end of the clip lead to the positive battery terminal and see if the solenoid clicks.  If it does the solenoid is working and you have a interlock/safety switch problem.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
