Ignition Switch

I had to replace the ignition switch in my 99 Sea Ray 190BR with a Merc Thunderbolt 5 engine. I changed it out one wire at a time ensuring I connected to the correct SIAB terminals. Now it won’t start, the solenoid just clicks. I changed the solenoid, same click. I changed the ignition module, same click. All gauges and instrument panel stuff works normally, just won’t start. There is a ground wire that was never connected to anything and I can’t find where it would even connect. Could it be that? If not, could it be the engine circuit breaker if it even has one because I can’t locate that either? Thanks for any guidance.
 
if the slave solenoid is just clicking try shorting the 2 large lugs on top, report results
B= Red wire, I= purple wire, S =Yellow/red Acc =orange
 
Your boat has two solenoids,
One on the starter, one typically mounted on the front of the engine.
Looking at engine on your left.It may be covered by a thin plastic rectangle cover. If not in that location look to find it.

It will have 4 terminals.
Two large on top and two small at bottom.

Two large, one RED, one Yellow with red stripe.

Two small, one yellow with red and one black (ground).

Jump from red on top to small yellow.
If solenoid only clicks its bad.

To confirm, jump large red to large yellow with red as already suggested.
If starter cranks that absolutely confirms slave solenoid.

So at this piont its not the ignition switch and most likely never was.

You could have jumped the wires on the back of old switch first to see if you only gotva click. That would have eliminated the ignition switch.
 
I will try that. I will add, it never was an ignition switch problem. I went to turn the key in the ignition and it broke free. Never even attempted to start before the internals just broke loose and the key spun freely. It runs/starts perfect every time until now.
