This all started with troubleshooting a slow crank issue. I started with cleaning all of my battery terminals and working my way toward the motor. After cleaning a terminal suspect of corrosion, I would try to crank the motor. Each time I tried to crank the motor, I would occasionally hear the starter solenoid clicking fast and the starter would not engage. The last thing I did was remove the starter solenoid at the motor. I found some corrosion, cleaned it up and reinstalled. I went to start the motor, turned the key to run, the tach safety check did its normal sequence, I could hear the fuel pump, and then I turned the key to start. Nothing happened and now the motor is completely dead. When I turn the key to run, the tach is dead and the fuel pump is dead. The trim and tilt does not work either. 

I have checked the 10amp fuse on top of the motor and it's still good. I have 12.75 volts at the starter solenoid on the battery terminal connection. What else should I check? Could it be just as simple as replacing the starter solenoid? Thanks, Kevin

 Have someone turn the key to "start" the engine and you check the voltage at the solenoid and at the battery.

I performed this check. When I turned the key over to start, the voltage at the solenoid went to zero. Voltage at the battery remained at 12.75v

As several folks have suggested, there is a high resistance somewhere in the path between battery and starter solenoid. Could be in positive or return path. The high resistance causes all the voltage to drop across it leaving no power for the starter.

You are going to need to find where the drop (resistance) is yourself. A voltmeter is the only tool required.

Check the battery cables where they go into the motor . The continuous flexing can take its toll

Google " voltage drop test " and there should be numerous articles and websites that explain and illustrate how perform it.

One of our members has written an informative article on starting system that you may find helpful.
