exhaust brake not working

[KSDP_PA]

worked 2 campouts ago.
1 campout ago was down south - no mountains - didn't miss it.
this weekend, back in the mountains - needed it.

turn on switch, take foot off gas - nothing.
no slowing down, no light on dash.

is there a fuse somewhere ?

We have an '06 Dutch Star and when our E-brake failed we fixed it by replacing a 5 amp fuse found in the basement compartment in front of the passenger side rear wheel. We found out where it was located by calling Spartan.

checked the fuse - good.

turns out one of the wires came off of the back of the switch in the dash.

all better now.
