Engine is a 2000, 200 Mercury efi, Serial Number: OT157051
Hello! After disconnecting the cranking battery and changing voltage regulators I went to try to start my motor and there was no click and no starter engaged at the turn of the key. I have triple checked my battery connections and cleaned terminals (as well as made sure battery is fully charged), and I am getting normal voltage to the incoming side of the solenoid. I then checked the little yellow wire (with red stripe) on top of the solenoid to see if it was getting voltage when the key is turned, and it was not getting power. I had ran the motor earlier that day and it turned over no problem, so I find it very unlikely that the neutral safety switch went bad in that time frame. It's too much of a coincidence that this happened after hooking the battery back up.
Any suggestions would be appreciated!
