Cigarette Lighter Recepticles Not Working

[sheltie]

I have two cigar recepticles that aren't working for no obvious reason.  One is on the dash and has a 20amp fuse.  I replaced it even though it didn't look broken and still nothing.  The other recepticle is next to the passenger seat on the wall and has no fuse that I can see.  Since it is also 12v, I checked all the 12v in the panels but couldn't find where the fuse was for it.  I also reset all the GFCI's even though I'm pretty sure they are for 110V.  Still nothing.

I use the dash one for satellite radio (and let me tell you that out here in west Texas there are NO radio stations AM or FM) and the other one is used for MS Streets and Trips which help me on the way.

I won't be able to check any responses until at least tomorrow because I'm on the road, but any suggestions would be appreciated.  FWIW, I'm electronically challenged and don't even know how to use a multi meter to check to see if the recepticles are hot or not.

When you catch up with the forum it might help to know what type/year coach you have. Is it Ford, Chevy, Freightliner...?
In general, there should be a fuse in your central fuse panel labeled AUX, or Cigar Lighter, or Utility depending. Also, is there anything else not working? Some coaches have a battery disconnect switch that will turn off power to these outlets and other devices to save chassis battery power. Cost me $60 to find the first time.
A trouble light or a multimeter might be handy to chase down the missing voltage.

Do you have a voltmeter? Can you verify that you have 12v at that fuse?

It's also posible there may be an inline fuse near the recepticle under the dash.

Have you tried the item in another 12 volt plug to make sure it works. Most 12 volt items have a glass fuse in the plug.

  A basic electricity/elecronic 101 course would probably go a long way... especially for RV owners.

Have you tried to use them when the motor is running.  Some are controled by the Ignition switch and will only work when in the ACC or ON position.

I have a 2004 Itasca Suncruiser (Workhorse) Class A.  Multimeter (I bought one and learned how to determine if recepticle is hot, they are not).  It's not the battery disconnect, but a good thought, thanks.

I just bought one last night and there is nothing at either recepticle.

I was thinking the same thing, but can't find any but the automotive fuse in the dash.  Could the inverter affect this situation?

Yes, actually I have three recepticles and the one in the BR works.  The two up front don't.

That's especially helpful in an emergency (?) like this where I have to learn it overnight with no sources available other than forums to help.   I'll keep it in mind though.

Yes, makes no difference.

I checked wiring diagram for 2004 Winnebago which may be similar or not. You might ask for info on how to get the diagram for your coach.
Yellow wire LS from outlets connects to fuse panel, battery boost switch,  and cable harness connector under dash that I did not pursue. White wire KF connects to ground bus. I would expect the "Coach stuff" to be similar with only differences being in the"Chassis stuff".
Did you check for 12 Volts to chassis ground or ground in the connector? The ground missing could cause this same indication.
In either case, if fuse is good at the fuse panel and you measure 12 volts at the fuse, you must have a disconnected / broken wire in the harness either the LS or KF wire.
Good Luck and let us know how it works out.

I've ran into two seperate 12v lighter adapters that had small fusable links on the back side of them. The first was in a Toyota truck I owned, plugged in a 12v compressor to air up tires after off roading, and blew that one, the second was in my Ford F150 blew it running a 400watt inverter and a skil saw. In both cases it required replaceing the recepticle itself.
