2006 Q4: Strange dash light and won’t start

[Omnialive]

Spent hours cleaning my boat yesterday to prepare for taking it out today. Tried starting it in the driveway before hauling to lake and it won’t start. I noticed a constant light on under the blower switch. This light goes off when the blower is on, but stays on even with master switch and ignition key off/out.
Can’t find reference to this light in my owner’s manual either. Thoughts?

Won't start and new light. Don't know what the light is for, but if you can crank the motor but it won't start, check your kill switch (Man Overboard)

Won’t even crank/turnover. Did check kill switch. I tripped it and then reset it.

If the key is turned ON, do the gauges turn ON?

 

[alldodge]

BTW what motor is in the boat?

The Volt and Oil don’t move. The trim motor, depth finder, horn, and nav lights all work.

MCM 4.3 L MerCruiser V6. Model

Look for a 15 or 20 amp fuse/breaker on the red/purple wire feeding the key switch. It will either be in the fuse box or can be a inline fuse on the red/purple wire

Nothing like that under the dash or fuse box. Did find an inline 20 amp shortstop fuse block at the battery.

It has an ignition fuse, just need to find it. Start with the red/purple wire at the key and trace it back

No red/purple wire off the starter but there is a solid red wire. I traced the red wire back to a coupling that leads straight back to engine. Only 20 amp inline is at battery I can find so far

I’ve found some 10 amp fuses, one for the yellow/red.

Also, I very much appreciate the assistance! I am not mechanically inclined in general and especially with marine equipment and haven’t ever had trouble with this boat until now.

SOLVED ( ): I maintain the battery off season inside my house on a trickle charger. Seems that two of the cells were close to dry and the battery could power everything but the starter. Seeing if I can revive the battery now or if a new one is in order

That's good, I've been cutting grass

Info for future.
The red from the starter goes to the 50 amp breaker on the motor
Other side of 50 amp breaker wire changes to red/purple
Red/purple goes to 10 pin engine plug
Other side 10 pin plug red/purple goes to 20amp fuse
other side of fuse goes to key switch
