OK, let’s back up and start over.
1. First, do you still have the junction box in the boat and cable plug on the side of the motor? I ask because so many have been hard-wired over the years.
2. You say you have a “meter” but don’t know how to use it. Is it a multimeter (checks voltage, resistance, etc)? Do you at least know how to check DC Volts? Or willing to learn?
If we knew the answers to these questions, it would be easier to help you.
EDIT: One other question, key turned on, does the electric choke work when you push the button?
