elec help Please, elec dist box

(Spent lots of time searching here and couldn’t find what I needed)


I’ve been having way to many RV problems lately. Latest is my bedroom fantastic fan and fan in bathroom quit working. All fuses turned out to be good when I pulled and tested them. Trying to find the problem, eventually lead me back to where the fuses are located. The “power distribution” panel. I then put a volt meter across the actual metal spade connectors that the fuses plug into and found that I have one that is not making a connection. So in my limited elec knowledge I believe that circuit is not making a complete the circuit.


One part of me wants take this thing apart and just replace or fix the spade connection on this one wire. Other part of me thinks the spade connections are one large piece molded into the plastic. And of course no part of me wants to change out the whole wiring complex for one fuse.

In the pic with screw driver in it, the screw driver is pointing to a silver colored screw that I think holds this thing together. If you’ve taken one of these apart before any hints? Are spade connections molded into plastic? Or can each one be taken out and worked on? Can I undo the silver screw and remove the part that the fuses slide connection?

What is the real name of the part that all the spade connections slide into? Only thing I could think of is “fuse circuit board connectors”.

Thanks

    I really enjoy watching people that know their stuff. Me on the other hand I take pic's or draw it out and even make labels sometimes and scotch tape on wires if elec. To many times if something moves water, anything elec, or anything that could result in 5 trips to store I really check good.

    I should be able to work some more tonight.

    They can come unsoldered but that would be rare. Your problem is most likey where the screw connection is for the circuit wire that terminates on the board.

    You need to remove the cover you are showing with your screw driver where you can see the screw down connections for the circuit wiring. Those connections can work loose real easy... They probably was not installed to tork spec at the factory.

    Provide the model number of the distribution panel and perhaps you can find a photo of the exact 12VDC circuit board on-line to show how the external wires connect to it..
    http://www.progressivedyn.com/pd5000_2.html is what I've found on-line so far. Good distribution but lacking info.

    Be careful with the distribution panel as both 120VAC an 12VC wiring exists in close vicinity here...

    Elec cord unplugged from house. Only elec I have to unit is 12 volt.

    Yes, I'm going to have to remove it to see underneath.

    How exactly are you testing the page like clips. The power will come in from one side and out on the other so there should only be power on one side.


    That's exactly what I was thinking. There should only be power on one blade. It would be unusual for that board to fail in that manner. Did you check for power at the fan? Or use your DVOM to make sure that you have a complete circuit across the blades for the fuse?

  • Check the lid pin on the fan. If it is sticking when the lid is up, no fan.
