Unknown switch function
 

On my 2007 Haulmark 3329DS I have a switch mounted on the wall just to the left of the fridge (between fridge and shower) and have yet to figure out what it does. The switch appears to be a 12volt momentary switch (looks just like the switches that were in the fifth wheel I traded in on this coach)mounted just below and to the left of the generator hour meter panel. When pushed nothing seems to happen, no noises, lights, etc from anywhere I can hear.

Anyone be able to bring me up to speed?

im gonna guess its a battery combine-switch....probably allows you to combine the engine batteries with the house batteries (in cases were house batteries are dead) so you can start the generator.

Thanks Don,

After reading some Google search results that is what I figured as well...hopefully I don't ever have to find out.

Ive got one two - I'm not sure it even works....and only NOW have i realized that even when i have the house batteries turned off, I've never tried the switch (to see if it works).

I carry jumper cables with me....never had to use 'em (thank god).
