What is this for part?

[1990HR]

I was asked to make a new post with the whole picture of where this circuit is at.
Here it is with both pictures.
Trying to find out what this could be used for.
Thanks for the help.

EDIT: Fixed the picture it didn't like an underscore for the name.

W% sorry link doesn't work.

For some reason the picture would not work so I just put the link of the page where it is.
It's at the bottom of the page.

My guess is a kill switch for the alternator.   Anti theft device. i??

As rick had said, other stuff gives clues.  In this case, given the circuit is jumpered across the 2 large battery cable posts, we need to know what the labels for those 2 battery cable posts are.

If that is a diode in the center and those cables go one each to your chassis battery and the coach battery then I would say it is a home made charging system for the coach battery that will charge into the coach battery but not draw from it. That is a total guess without knowing where the rest of the cables go.

I don't think that diode is capable of handling the kind of current those cables are capable of.  The white thingy looks like a ballast resistor.


More input is needed from the OP before the other classic Winnebagos  doctors can offer a diagnosis.


This seems like a recent "what is this for" generator fuel kill switch thread.   


This is one of the things that draws people to this place.  Crazy people and a good mystery!

The only thing I know is it's not stock.
It has always been turned off and everything works fine.
I was hoping someone has seen this before and was like "Oh ya, that's a ..............."
After vacation I'll see if I can figure out what exactly it's doing.

Where do the big cables go to and where from?

[joanfenn]

we have one of those also.  The fans quit working in the engine compartment on the side of the road one night and hubby ran wires inside the unit to hot wire them.  He finally put a rocker switch on it.  They cool better now then the original setup did.  Better then stock.
