Hi, I have a 1990 Bayliner capri and I am wiring a new stereo in. I have heard about radios drawing (for the clock and presets) enough over a couple weeks to drain the battery. If I want a toggle switch to turn the radio on and off so I don't have to have the boat on to use the radio and I wont drain my battery when storing it, how would I wire this in. I have a red black and yellow on both the radio and the boat. Do i combine the red and yellow on both sides and put the toggle switch in the middle? or do i run the yellow from my boat to the red/yellow on the radio? Or am i just wasting time and should i just run red to red yellow to yellow and chanc eit draining the battery? input appreciated, thanks.:confused:

i believe yellow and red can not touch untill at battery [believe]
what i would do is, red to +, black to -, and run yellow threw a switch, back to fuse block on the +

I have the yellow (memory) and red (power) hooked together right off the stereo into a single power wire. In my experience they don't have to be run directly back to the battery independently.

The yellow wire is the station memory/clock power and it must be connected to a constant +12 volt source to save the stations you've preselected and to maintain proper time. The boat would need to sit for a month or more before it would run down a battery as it draws only a few milliamps. You don't need an on-off switch for a radio since it already has one, If you put a switch in that wire you would need to reset the clock and all of the station presets every time the switch was turned off. If the boat has a battery disconnect switch you also don't have to worry about it since the switch kills all power to the boat.
