Since the battery is good, let’s look at other potential causes.

First, check the starter motor. It might not be engaging due to a faulty solenoid, bad wiring, or a worn-out motor. Are you getting power to the starter motor? Ensure all connections are clean and secure.

Another possibility is that the engine is seized. This could be due to rust or internal mechanical failure, like a broken piston or failed bearing. Try manually turning the engine with a wrench to see if it’s free.

Also, the starter button could be faulty. Worn-out or dirty contacts inside the button can prevent it from sending the start signal. Is the kill switch in the correct position? Lastly, inspect the wiring and fuses for any issues.

Hope this helps, and good luck getting your Scrambler running again!
