strange odor

[David Brady]

Thanks Pete,



I neglected to mention that the smell is only apparent when underway
and

dissipates when the coach is parked (regardless of shore power or
generator

operation).



I also noticed that my right turn signal on the toad isn't functioning,
the brake

lights on the toad do work, which tells me that it's not the bulb.
Prevost Car

told me that the trailer light module that I use is prone to meltdown
and catch

fire, so I purchased a draw-tite module for replacement. I haven't
installed it

yet. This could be the cuplrit.

From time to time, I encounter that "electrical smell" in one
part

or another of the coach. There are electrical distribution panels

(12vdc) above the windshield and in the rear closet (as well as below

the driver's window on newer coaches or across the front of the coach

on the wide body models).



Several times, when I smelled "the smell" I've searched and checked

high-and-low but have not found anything clearly identifiable as the

source. (Although I note that the last electrical smell was coming

from somewhere near the inverters and one of my two is apparently no

longer inverting -- I'll find out tomorrow when I disconnect and hit

the road.)



So, I don't really have any suggestions -- and it is likely not a

good thing going on -- but it may be weeks (months or years) before

something actually occurs. Indeed, it took two years from the time

that my Kool-o-matic started having some odd symptoms until it

actually failed (and I've now clearly determined that the K-o-m motor

is dead). There wasn't (much) smell to the fan going out, if only

that any smell it generated went out the vent when the fan was

running...



I've also determined that appearances can be very misleading. For

example, in the case of the Kool-o-matic, I'd have sworn (after

inspection) that the thermostat was defective (due to a considerable

build up of 'crud' on the back side of the lower 1/3 of the circuit

board) -- but after a very thorough troubleshooting session, I proved

to my satisfaction that the thermostat works just fine, despite the

appearance.
