What is this wire?

[mdchachi]

I just noticed a disconnected green wire and I'm not sure if it was disconnected from winterization. Can I safely connect it to the plus battery terminal? Any idea what it's for? Everything seems to be working as far as I can tell. I didn't check the bilge pump though.

Thanks.

Are you really just going to connect a wire of unknown purpose to the battery? Really?

I was kind of hoping somebody would be able to identify it before I did that.

Well it's green, typically that's a ground. Are there other ring terminals that look like that? If not are there any aftermarket accessories? Can you follow it back?

Don't just connect connect to battery! Follow the line back to the component and identify [emoji27]

Ever find out what the green wire goes to? I have exact green wire disconnected....post winterisation.

definitely not original. i would imagine aftermarket radio or something.
take a voltmeter to it and check dc voltage between the terminal and the positive & negative batt terminals.

If it is a radio (or something looking for a ground), you should see 12v between the wire & neg batt. If it is a power wire (and someone used green just because) you will not see 12vdc between wire & neg.

I added a wire to my radio to maintain station memory, seems oem didnt think of this. perhaps this is all it is. Something on your boat doesnt work.
