12v outlet wiring diagram

[ryandmartin]

Want to ask before I reach out to the dealer and have missed something stupid.

The 12v outlet on my new R5 seems to have stopped working. It’s located above the glove box on the port side, next to the USB plug. The 12v outlet doesn’t work, but the USB plug does work.

I can’t figure out why, unless it’s really broken. Battery is switched on, and I can’t seem to find any switch or inline fuse that would cause the problem. I haven’t had any issues in the past, and it didn’t suddenly stop working while we had something plugged in. We typically use it for an air compressor for the tubes.

Does anyone know the wiring scheme of this thing? I checked the regular breakers and everything is fine, and it would seem that it would be on the same breaker as the USB plug (working) right next to it. I can’t find any Cobalt wiring diagrams or info that would help troubleshoot.

I can't help much but some of those compressors draw alot. So I'm sure they put a fuse somewhere for it.

Any luck on this? I’m having the same issue.

Hey Derx.
Welcome to the Cobaltchat forum. So glad you found us!

This is almost always a fuse or breaker issue. Sometimes it’s the component. A multimeter can tell you quite a bit. Switch it to the 12 volt setting and find where the power ends.

Any pics of your Cobalt?

Again welcome aboard mate!

Isn’t the USB port on the port side tied to the radio? I think you may have to have the radio turned on for that one to be energized. However, the one on the right side of the helm as well as the outlet in the bow (also port side) are energized whenever the batteries are “on”.

USB is 5V, not 12V, so is likely coming from another device such as the radio as TBully mentioned. The 12v accessory power port is probably run via its own line to either the rear of the boat or to the helm, where power is broken out to all the various dash devices and fused or run through circuit breakers. Cobalt marks some wiring harnesses with numbers or other tags, so if you can see that the power connector coupled to the back of the 12V outlet is marked "094," you can search for "094" under the dash or wherever else all the dash power wires are broken out. There is probably a fuse or breaker bank at some point, such as under the dash, that the positive (red) wire will come from, and a big bus bar that the negative (yellow or black) wire will come from.

If you have a helper, there's always the old school method of tugging on one end of the wire (such as behind the 12V outlet) and having someone watch behind the helm to see what wiggles. This may be faster than trying to trace it with a continuity tester or meter wire by wire, but obviously that works too and is good to verify once you think you've found it.

It is the 12v outlet on the port side next to the usb. USB is probably not working as well though. My son plugged in the compressor to that outlet while the stereo was on and must have overloaded the circuit and now the stereo as well as that outlet are all out. I’m assuming they are connected somewhere but can’t find the fuse. The breaker in the panel under the dash is not popped. I checked the automotive fuses For the amp by the battery switch as well.

Thanks for the welcome. Here’s a photo of the boat

Not sure if it's a surf model?

That’s a year or two before the surf model.

I wouldn't think they would tie into the fuse panel on the engine but check back there on top of the engine there maybe a fuse box. Mine has one. Not sure on the new Gen Volvo though. Also I guess check under the helm. I guess can the dealer or Cobalt cust assist too. It's there somewhere. Please post back when you find it.

Ah roger that. The WSS logo got me as I was thinking Wake Surf Series.

Right I was trying to see the props and couldn't see it. Yes the good Ole Water Sports Series. One of my fav boat colors and graphics.

I did check there but only dash and engine components on the panel by the engine. I’m thinking it has to be something in-line but not sure where it would be. There’s a panel inside the head I’m going to take that off tomorrow and see if maybe it’s in there. Otherwise I’ll just grab a voltmeter and try and trace it out I guess. Dealer didn’t have any good info for me.
