Rinker 280 with Volvo Penta GXi-H won't crank

This is a new boat to me. Been sitting in storage for 10+ years. I have turned engine over by hand. Belt off, water pump off.
Rinker 280 with Volvo Penta GXi-H won't crank. Turn key to ON - voltage gauge indicates 13 volts. Turn key to START - voltage drops to 0 - no starter solenoid or starter noise.
New battery, starter removed and bench tested, Jumping starter wire will engage starter. Inspected neutral start and kill switches - everything looks good. For some reason key won't engage starter.
I have looked all over for a wiring diagram and color codes for Rinker key switch wiring and for the engine.

Here are your wiring diagrams:

Here is a generic key switch. Definitely check that you don't have a bad switch with thee multi-meter; you can alternatively "jump" the terminals with 2 alligator clips to see if the switch is bad.
I installed a new battery last November. I returned it this month under the 12-month warranty for another new one. Terminals are fine. I removed the starter, bench tested it, cleaned the terminals up and re-installed it. I jumped the solenoid and the started engaged. Water pump is off, serpentine belt is off and turned the engine with a wrench (plugs are out).
I have inspected and jumpered the switch with no change. I'll go over it again with your notes and a voltmeter and try the jumpers again.
Thank you for the boat wiring diagrams. They only show the key switch harness plugging into the engine harness. I have no engine documentation (ordered).
The kill switch and neutral start are on the engine wiring harness. I can jumper the neutral start microswitch but have no access to the kill switch (molded wires and can't see where they go.
I'll go over the switches again this weekend. I'm an experienced electronics tech. This isn't that difficult to troubleshoot. I really need the engine schematic to go forward.
EDIT: Oopsie, I forgot you have a Volvo...below is the deal with a Mercruiser.
But a quick search shows that it too has a start relay somewhere, but can't say for sure. If it is anything like Indmar, there is an ignition relay next to it, and you can swap them to see if that's the failure point.
If so, now go "upstream" to the slave solenoid (start relay, as I prefer to more accurately call it) which is next to the other 2 relays near your ECM, relays, and engine circuit breaker. Jump those 2 terminals and if it turns over then I think you found your problem.
It's #23 in this diagram:
Off position only has power on "B" wire.
Turn left to ACC has power on "B" terminal and "A" terminal.
Turn right past OFF to IGNITION "I" terminal, "B" terminal,"A" terminal and "I" terminal all have power. So far this seems correct.
Turn key right again to START position (yellow w/red trace) only "B" terminal has power. This is wrong.
Got a new key switch. Now in START position I have power on "B" terminal,"I" terminal and "S" terminal. Also check power at neutral switch(yellow w/red trace) and the switch itself - 12 volts - which I did not have before.
Next I move to the engine and start troubleshooting at the starter relay (yellow w/red trace).
Yellow w/red trace goes from key switch to neutral start switch to R3 starter relay to starter solenoid. Passes thru a few connectors along the way. Hopefully it's a bad relay - easy fix.
I have not found any wiring information for the kill switch in the documentation.
I found it at https://www.marinepartsexpress.com/schematics/volvo-penta

UPDATE: New harness was exactly what was needed.
Great Laker Skipper bought a lot of Rinker inventory when they closed. I searched Volvo-Penta harnesses and came up with nothing. The Boat harness has a "Deuetch" connector on the harness. I was going to build an adapter. When I searched for that connector I found the Mercruiser adapter. It was the right length, color codes looked correct, pin counts and connectors were right. $75 item.
Did you ever jump the slave solenoid to see it cranked?
When harness adapter was installed it cranked off the key as expected. I'm not going to put gas in the boat and try to start until April. Have to get old fuel out in the Spring and start it. I'm sure I'm in a good place.
It was a matter of stumbling on a Mercruiser cable on Great Lakes Skipper and learning that the Volvo-Penta had the same engine interface (both engines made by GM).
