    Posted: October-18-2019 at 12:23am
I just got a 1987 Ski Nautique 2001

When I turn the key to the "on" position, nothing has power. But when I press in the " ignition " button and have the key in the " on " position, everything receives power.

Even the hour meter advances, even though the motor is not running.

Is this correct ?

Is the " ignition " button supposed to act as main power supply along with the key ?
Even the radio only comes on when the key is in the " on " position and the " ignition " button is switched on.

Any insight would be much appreciated !

Sounds right to me. That's the way it was built.

Here's the much used TRB diagram that shows the wiring going up to your key/dash. it doesn't show all the dash wiring inside the purple box that says "dash switched feed".

TRBenj is the guy who drew it up if you're brand spankin' new to the site



The 20 amp breaker takes away dash power and with the breaker ON and the key ON, the hour meter runs.

It's sensing power when the key is in the ON position it's not smart enough to know if the engine is running or not

The 20 amp breaker is labeled and called the "ignition breaker" but it really takes away all the dash power.   

You don't have an "accessory" position on the key, so it has to be in the ON position for radio power and power to all the instrumentation

And here in the link below is an 87 dash wiring diagram from the "miscellaneous files" section of the CCF reference section

It's not the clearest, easiest thing to read

You're doing it backwards. I would hit the ignition switch and then turn on the key. Consider that ignition switch sort of like a battery switch in a newer boat. It provides the juice to everything and then you go from there.

Thanks for all the great info !! I feel better now.

I was a bit surprised to see that the key has to be " on " and the " ignition " button needed to be depressed in order to run the even the bilge pump and radio.

But if that's the way it was designed, I am ok with it !

My fear was that someone had rewired stuff. That is usually a bad sign. Lol

I think you'll find that the bilge pump will run with the ignition breaker on and the key OFF.

It's from the dash hot feed , before the key switch. See the TRB diagram again right after the 20 amp breaker and before the key switch.

Thinking about it, I think you'll find that the blower, the bilge pump, the lights and the horn will all work with the ignition breaker ON but the key in OFF. Also if you have an accessory switch it gets power too.

With the ignition breaker ON and the key ON you then get power to the instruments and the ignition system

I was out there tonight and what you said is correct !
Thanks again for helping put my mind at ease.

But I did notice something weird. If I have the " ignition " switched on, the oil PSI is maxed out. The needle shoots to the far right. But then when I turn the key on, it goes back to normal. ( at least, I think this was the sequence that caused the oil pressure to tac out )

When she is running, the PSI looks correct, which is what matters most.

I'd check that sequence again.

And I'd suspect the wiring on the gauge being wrong

Could be just me but in boats I've had with that ignition breaker, I've always left it in the ON position since I didn't really see any need to kill dash power when it wasn't running
