Is it possible to troubleshoot a 12 volt electric?
Troubleshooting 12 volt electric is a mystery to most everyone afloat… A friend of mine recently purchased a vessel to sail around the world, went down below, flipped a switch on the panel marked running lights —and nothing happened. He was dumbfounded.
Can a 12 volt problem cause a refrigerator to fail?
A 12-volt problem can cause failure of other appliances and systems if they have 12-volt power to their controls. The refrigerator and air conditioner, even running in propane-fueled mode or on AC power, require DC voltage for their logic circuits, and so may fail to operate when there is a DC system problem.
What should the voltage be on a 120V circuit?
Phase (hot)-to-neutral voltage. This measurement is the voltage the load will see. Typically on a 120V circuit, you should get a reading of between 115V and 125V. Let’s suppose you measure 118.5V. Neutral-to-ground voltage. This is a measurement of voltage drop (also called IR drop).
What causes a voltage drop at the receptacle?
Neutral-to-ground voltage. This is a measurement of voltage drop (also called IR drop). It’s caused by load current that flows through the impedance of the neutral wire. Let’s suppose you measure 1.5V. Phase (hot)-to-ground voltage. You can think of this as the source voltage available at the receptacle.

Can a 12V battery give you a shock or not?
For me the only difference between a small 12V battery and a big 12V battery is how long it can give you a shock for, but both would give you the same shock (ie, both would make the same current pass through your body). 2) Why didn’t the guy in the video get a shock?
How do you turn on a 12 volt battery?
This is a tiny little thingy which looks like small screwdriver or ice pick … with a wire coming out the top of it. If it senses 12 volts, it lights up. Put the alligator clip attached to the wire onto the negative post of your battery, and touch the positive post with the pointy part. The bulb will light.
What’s the difference between 12 and 110 volts?
First off, everything I am about to tell you concerns 12 volts only. Most vessels have a 12 volt system for use away from the dock, and a 110 or 220 volt system to use while tied up or when the gen/set is running. These are different. 110 volts (and higher) can and will kill you—12 volts is much more benign.
