Bulb Check! - Sometimes They Are Out And You Don't Even Know.

Nice Tail!
    I only had one tail light working. I don't know when it stopped working, but since we have yearly DMV inspections and mine is due by the end of October, it could have been almost a year! Yup..never noticed. That's bad. I know I should check all my lights (and oil/fluids/air) before each trip, but sometimes I only do SOME of those items. I know...I'm bad. From now on, I will be fully checking my rig before I move out. It's a smart thing to do. Well, what about changing light bulbs in RV lights? Sometimes it's really easy. Sometime it's not. My tail lights were...in between. Here's what to do.



Big Chunk Of The Tail
Take a look at your tail lights. Are they separate lenses, one big lens, are there screws holding lenses on to a separate assembly? None of the above? Well, the first thing to do is gain access to the bulb itself. In my case, it was a bit more complicated. I had to remove the entire tail light assembly from the back of the RV, lens, reflector, everything! They are about 2 feet long, with 4 sections of wire harness coming out, so that was awkward. Thankfully, they aren't all that heavy. Once removed, I could see a bunch of sockets on the back that push in and twist to remove. As long as you line up the curved slots properly. Mine have 2 smaller curved pieces and one larger one, so they will only come out when everything is lined up. Even then it required a bit of...finesse.

I should have found a small table or something to lay the lights on after they were removed so I didn't have to keep holding them up. Ah well, next time. I managed to get all the light bulb holders and bulbs out of the fixture. HINT: Remember which bulb socket goes in which hole! (Don't ask.) It was pretty obvious which one wasn't working. The bulb was broken. And sharp. (Again, Don't ask.) After the bleeding stopped, I found another 1157 type bulb and replaced it. Didn't work! Hmmm...Upon closer inspection, the bent metal strip that makes contact with the metal ground of the bulb was broken off. I soldered on a small piece of wire to make contact and it was fine. I SHOULD have replaced the socket, but my tail lights are sourced from a 1989 Mercury Sable (mounted upside down!) So I would have to research a bit to even find out what socket it was! The fix should hold for a while. At least until I get back from my long trip next week. Of course, I will be checking operation each time I stop. Well, maybe not EACH time, but more frequently for sure!

With everything working, I put all the light sockets back in the lens/reflector housing and gently put it back on the RV. All done. Mostly. After putting the acorn nuts back on the assembly, I noticed one side was dimmer than the other! Huh?!? OK..so took it back off and looked at the terminal. No difference at all, voltage wise. After fiddling a while it turned out to be a bad/loose ground coming out of the trailer hitch wiring! That was a couple of hours of hunting... So I fixed the ground and (since the tail lights were back off, I replaced all the bulbs with LED versions. MUCH brighter now and less Amp draw to boot.

All in all...pretty easy. You can bet I will be checking my lights/signal before EVERY trip! Fool me once, shame on you. Fool me twice...shame on me!

Electric/Induction Stove Tops - Better Than Propane?


Typical Propane Burner
    Recently, I had to replace the 240 Volt AC electric stove top in my house. The glass surface had cracked at some point and the crack had finally expanded across the whole face of the stove top. Ah well...it did last 25 years, so I got my money's worth. While removing and replacing it with a newer model (still with a glass top) I noticed it could run on either 120 or 240V. Of course, at the lower voltage it wouldn't heat as fast, but would work. What about using these in an RV (without a glass surface obviously!) -- is that possible or even desirable? Or do you prefer a propane gas model?


Vintage Stove Elements
In the old days, electric stove tops were pretty simple, a coil of heavy  gauge metal that heated up when you passed electric current through it. You adjusted the temperature by changing the amount of electricity going through the coil. Later on, they began mounting the coils below a glass top so the surface was smooth and uninterrupted. Later still, you were given a choice of traditional knobs or touch controls. All this is great and works well. But what about in an RV setting? First of all, these type of stove tops use a lot of power. Usually between 1000 and 3000 watts of power! That isn't feasible in an RV unless you are going to run a decent sized generator or always connect to shore power. That, in and of itself, would put the kibosh on electric stove tops for RV use. But wait! There is another type that may be worth a look.

My Small Induction Cooktop
Induction cook tops are VERY efficient: 84% energy transfer versus, best case, 74% for traditional electric cook tops. The efficiency translates to faster cooking times which reduce the overall energy use. A 2000 watt electric stove element uses about 320 watt-hours to boil 2 quarts of water in about 10 minutes.  A 2800 watt induction unit boils 2 quarts in about 5 minutes, using 225 watt-hours. If you reduce the power level to 1300 watts it just about doubles the time back to 10 minutes, so it is a bit more efficient. Compare this to a propane burner. It will do the same job in 8 minutes or so and requires about twice the power overall. Of course, you need to convert from BTU's to watt-hours since it's gas.


My Newly Installed Glass Cook Top
For me, the replacement would be useless. I rarely have that much power to spare while boondocking and propane stoves require no electricity. I already have a large, frame mounted propane tank on board so I'm good. It is way cool to watch an induction cook top boil water quickly even if you need a ferrous or magnetic bottom on the pot to get the ideal energy transfer. It's also really neat from a technology aspect. That's why I have a portable one. I like to cook in my RV, from simple recipes to complex meals. Breakfast is always a favorite! You can't beat the almost infinite temperature control of a gas valve. You can get close with induction.... Still, not ready for prime time on board my RV. 

As always....YMMV!
