Battery Wires

[bbroskey]

I have a 1978 Johnson:<br /><br />I have three wires going to my positive battery terminal. I know that the thick one is for power, but there are two thin wires a yellow and red. The red has a fuse on it. Does anybody know the details of these two wires ? Thanks for the help.

Re: Battery Wires

Chances are the red one supplies power to a fuse panel for the accessories. Yellow one is probably the power for something that was added on. It should have a fuse also.

An easy way to check is to disconnect one wire at at time and then turn on stuff in your boat and see what no longer works.<br /><br />In my boat, I have extra wires going to the battery also for things such as lights and bilge pump.
