Why Does My New LED Light Not Work?

A customer of TechnoRv Ordered a LED reading light (67-CW67) to replace a 1383 incandescent. The bulb base is the single contact Bayonet. When he received the new LED it would not work in the fixture, but it would work in another fixture, and his old incandescent worked in the fixture that the LED would not work in. Seemed a bit confusing as the problem did not follow the bulb, nor did the problem transfer to other fixtures. 

The RV industry can be a little confusing at times.

With the incandescent light that was installed at the OEM level in the past , nobody was putting the wires at the same place all the time because the element (Incandescent) was working on both sides on the wiring installation.

Enter LED lighting and you deal with polarity. The reading fixture that he was trying to install the replacement with the 67-CW30L is polarity sensative, so the positive needed to be at the end of the bayonet and the ground on the round metal base to be able to work the proper way. I asked th…

RV Electrical Safety – Safely Plugging Your RV into Power

Image
In my last blog post I talked about what a volt is and how it can be set into motion by pushing current through a path of least voltage pressure. In some cases this can be your body. In short, if you touch something charged with 100 volts with one wet hand, and then touch something else charged with zero volts with the other wet hand, then the 100 volts will be set into motion through the conduit, in this case, you. So, not to get all scary here, there are some basic safety measures to take when plugging your RV into the campground pedestal. If the pedestal is operating correctly, then there should be no problem, but just in case, think about how you could avoid potential voltage pressure from being released. First step is to make sure the circuit breaker on the pedestal is turned off. With only one hand, and standing on dry ground, flip the breaker off. Now, with one hand, and never standing or kneeling on wet surfaces, plug your power into the pedestal. (Example - you wouldn’t want …

RV Electrical Safety Basics - What is a Volt?

Well, the professor of electrical engineering at the local university will tell you that a volt is a standard international unit of electric potential. What? Why do I have the definition and still don’t know what in the world it is. Let me break it down into terms that I can understand, and then certainly the masses will understand too. Think of a volt in terms of pressure. An electrical unit waiting to be set into motion with the right circumstances. Like a balloon that is under pressure. When it is popped, the air is set free into motion. So what sets a volt free? 
Have you ever been shocked by a door knob? For some reason the doorknob was holding on to some precious volts, under pressure and waiting to be set free, and when you came along and touched it, you were the conduit to allow the pressure to flow. So where did it go? Well, it went through you, from one part, to whatever other part of you that was touching something that had less volts than the door knob. If you were standing…
