Finally getting to installing the last of my most recent BoatFix order...

That SPECIAL MST70 Stereo... Page 7 of the manual says the RED lead goes direct to battery and is both Main Power and Clock/Station Memory. Then the ORANGE lead is only On/Off Control and goes to the ACC terminal...if it's a Car.

In a boat, the RED would have to go to "Stereo Memory" which is a circuit Sea Ray provided to keep the memory warm with the battery switch Off, same way the bilge pump works. Then ORANGE would run to the "Stereo" circuit but only allow the unit to be turned On/Off when the Battery Switch is ON.

Is that the way yours worked out? I guess it'll work out, I just wasn't expecting to run 10A into the stereo when the battery is off...
