I own a 2005 McGregor 26 sailboat. I had a Standard Horizon CP150C installed in my boat. I recently moved my boat to British Columbia, Canada and to my surprise my GPS unit did not power on. Although it is an old model it is brand new. I am the original owner and never had the opportunity to use in the lakes I sailed in the Prairies. I took the GP

S and chart plotter for inspection with a Standard Horizon licensed service shop in Vancouver, who checked the unit and found no problems with it. I took it back to my boat and it still did not power on. This clearly indicates that there is a wiring problem. Because my boat is presently docked in a remote place I cannot get an electrician to check my wiring. So I have to find a solution on my own. I opened the side of the cockpit to check the wiring to the GPS plug and [the wiring] looks OK. I went all the way to the battery connections and they also look OK. I visually checked the fuse box connections and also look OK. I am by now completely puzzled about what could be the source of the problem. Any suggestions and ideas to help solve this problem are greatly appreciated. While making a careful visual inspection of electrical circuits is a good way to locate problems which have occurred when there is a clear physical manifestation of the problem, a visual inspection cannot always detect a bad connection. To test an electrical distribution circuit, begin by testing for voltage at the source of the voltage. Move along the distribution circuit with your test voltmeter, checking for voltage at each point in the electrical distribution where there is any sort of connection from the source. You should be able to easily located a bad connection in this manner. One can often find a problem by drawing/sketching a wiring diagram of...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
