Today was a nice day - other than the haze from the Canadian forest fires. Warm and sunny, though, and I was able to take advantage of my wife & daughter's flower planting frenzy to do some exploratory surgery on the buggy. I decided to remove some of the warning and scene lights on the passenger's side to see what was going on, particularly since more wiring would be added for the refrigerator and the heater (both have to be permanently installed to qualify for a MN RV license plate).
My 10 ft stepladder is just tall enough
Visibility was less than perfect - the housing for the old (and removed) IV bag heater obscructed part of the view, with the reflective insulation also hampering things.
Murphy's Law being what it is, arthritis can rear it's ugly head when there's some ladder work, and it did. My productivity was far from optimal, but I got the scene light and the warning light removed - both were Whelen 97 series. The lights were equipped with 3-conductor plugs so a fixture could be used for both backup & warning, or stop & turn signal. Thankfully, mine were just straight 50 watt bulbs, and will probably be a wee bit cheaper than a dual element bulb.
My ceiling insulation is 2" thick foam chunks, wedged in place. Some of them vibrated loose in the last 15 years or so, so I'll probably wind up using some sort of a 3M contact adhesive to stick them back in place.
My light fixtures were held in with different types of screws - the scene lights were held in with self tapping 10-32 machine screws, while the warning lights were held in with #10 x 1" sheet metal screws. The sheet metal screws are Whelen's suggested installation, but I don't care for them, so I ran a 10-32 tap through the holes and used 10-32 x 1" phillips pan head stainless screws. I added a drop of medium Loctite as well since these would probably vibrate loose otherwise. NOTE: all of the 10-32 screws I've found have a coating of Loctite on them.
And just to keep Murphy happy, one of the existing 10-32 tapped holes was stripped out. I could have added a nut by reaching through the other light cutout, but instead, I drilled out the hole to 1/4" and used an aircraft rivet-squeezer to press in a 10-32 press-nut (AKA: clinch nut).
So, a mere 3 hours later, I buttoned things up - tomorrow, I'll do the same to the driver's side. Since the driver's side doesn't have the IV bag heater compartment, I should be able to see what I have to work with a lot more easily.
The right front corner - note the ceiling insulation pieces. The red tape on the convoluted tubing indicates that it's source is the driver's console.
Another view - note the corner of the IV bag heater.
10-32 press nut
Rivet squeezer - using flat upper and lower dies it does a great job on press nuts.
