12 volt system 2006 jayco

[JoeCool98]

2006 Jayco 12 volt system hook up to battery. I have 2 white wires that are supposed to be hot. It keeps blowing reverse palarity fuse. I have no power but to my plugs and microwave. Please help.

Lots of people have found that the white wire is ground. Blowing those fuses would indicate you have hot/grd reversed. Does the white wire drop ddown and connected to your frame. Anyway, your grd wire will be connected to frame.

Normally a camper uses WHITE as negative and BLACK as positive. Even your 2006 should be that way if any previous owners have not modified it.

Typically you will have 2, possibly 3 wires on the positive terminal of the battery. One heavy cable with an in-line fuse, one smaller wire for the breakaway switch and one for the electric tongue jack if so equipped.

The plugs and microwave are 120V AC items. They have nothing to do with the 12V DC system and battery.

Let's take this one step at a time.

- Disconnect your shore power cable.
- Disconnect any cables you have connected to the battery.
- Make sure your battery has 12VDC at the battery terminals
- Check/replace any blown fuses
- Locate the white wire that is connected to the frame of the TT and connect that to the NEGATIVE terminal of the battery.
- Take the GREEN wire (with inline 30 amp fuse) and connect that to the POSITIVE terminal of the battery.
- Check to see if your TT lights work, radio...

You should have 12VDC battery power to the TT's electronics (Radio, Lights...)

Let us know how that goes... and we will continue from there

By the way... welcome to the forum!!

OK, now you know that you have 12VDC to the TT. Let's do a little inventory. With the Shore Power still disconnected, see if each of your TT's 12VDC items are all working:
Lights
Fridge
Ceiling Fans
Fridge (running off of LP)
Water pump
12VDC Accessory Outlets
Stove vent fan
Awning - if you have one (Just tap to see if there is power)
Slide outs - if you have one(just tap to see if you have power)

Let us know the results, we will then move on to your other cables if they are not connected yet
