Amp meter wiring diagram?

He says 1st jumper goes from radio to input side of amp, then go from input side of meter to antenna side of amp. I read somewhere else to go from radio to antenna side of amp, input side of amp to input side of meter and last antenna side of meter to antenna. BTW my jumpers are 18″ does it matter? Ditch the illegal amp. I’ve seen lots of your sarcastic replies, did you get kicked out of the ham forum? Yes I had a license for 10 years and anal ham operators are why I let it expire. You want to place the VSWR meter last in line.

Digital volt and amp meters for DCC layout

June 05, , Nowhere in the Extra Class study manual did it tell which amps work with which rigs, and how to connect them without letting the smoke out of something. Because that can happen. By looking at the schematics and with help from others, I did pick up a few things. Inside my FL amp there is a relay that has to get energized in order to route the RF input signal through the amp and connect the resulting signal to the antenna, and also to tell the amp to wake up and amp.

Enter the volt meter. As a replacement for the ammeter, the volt meter will also tell us The ammeter is safe and more informative than the idiot light. AMMETER HOOK UP Two wrong ways and the right way WRONG WAY #1 is to connect the ammeter with both the battery/solenoid and the Folkmann Forgotten Ammeter.

OK first off, I am thankful for the wiring diagram provided by mbkerk. I have been getting ready to start this little project of installing my amper gauge. However I have hit a little snag and I am really confused. To start with, the amp gauge has a plus and minus terminal on it. Secondly, I have found my fuse but the two red wires which connect into the fuse are coming out of a black condiuit which masks their locations. So how am I to install the amp meter after the fuse when I don’t know where the wires are coming from which go into the fuse?

And the other thing is, how do I connect this amp meter up to the thing when its got both a plus and minus side?

Amp Meter Hook Up, Help

How do you lay up wires? There are 2 main ways of laying up wiring used in common practice.. The first is to lay the wires in a bundle keeping all wires untwisted and then tied together with lacing tape or coated Kevlar yarn..

Then hook up the jumper coaxial cable that comes with the amp to the output on the amp. Run the other end of the jumper cable to the back of the CB, and plug into the input for the antenna. Hook up the standing wave ratio meter to the linear amp as per the directions on the meter.

AMP gauges at the dash are troublesome. They should be by-passed, and then install a VOLT gauge. With normal but frequent use, most of these Dodge trucks will have electrical wiring problems. The first to fail were often the trucks equipped with factory air conditioning. The air conditioning system adds a significant electrical load.

The additional current flow when using the air conditioning and increased resistance with heat will break down the weak areas more quickly.

How To Wire an Electric Meter

It is a misconception that this amp RV service is something special. From this common service we can draw or volts. Each leg is 50 amps volts.

IDEAL Clamp-Pro Clamp Meter Amp with True RMS measures up to AC with auto/manual ranging. It has tapered jaws with a hook tip for a more secure clamp.

How to Install a Car Amp Correctly installing an amplifier is not particularly easy, but it is an important part of getting a quality sound and avoiding technical mishaps. Installing an amp can be done without the help of a professional, allowing you to get great sound without an installation fee. Steps 1 Mount your amplifier on a solid surface that will not conduct electricity. In other words, do not mount it on a metal surface.

Make sure you know how to reactivate your radio before doing this, if your radio has a security system. You can put it through an empty rubber grommet in a factory hole. If there is no available hole, use a power drill and steel bits to drill one. Start with a pilot hole and then work your way up to a size that will fit your wire. Paint the hole’s edges to protect against rust.

Put a rubber grommet in the hole to keep the wire from chaffing.

amp meter hook up

The input stage is biased so that the supply voltage is divided equally across the two complimentary output transistors which are slightly biased in conduction by the diodes between the bases. As the bias current increases, the voltage between the emitter and base decreases, thus reducing the conduction. Input impedance is about ohms and voltage gain is about 5 with an 8 ohm speaker attached.

The voltage swing on the speaker is about 2 volts without distorting and power output is in the 50 milliwatt range.

Take the coax coming out of the amp and plug it into the meter input, then take the wire coming from your antenna and plug it into your meter output.

However, before I begin, let me catch you up to date, especially important for those of you who aren’t quite up to speed. I’ve been one of the people asking this question, and it’s been long reported to me that the FIP trucks had a wiring harness with a ‘shunt’, which powered the ammeter. However, my findings today show differently. As Dirty Harry once said, “A man’s got to know his limitations” After I explained the basics on Ford’s setup, we set out to find out all we could.

And I should mention, he was very patient with me today, trying to help me understand a lot of the basics I’m going to to my best to try to explain what I learned today here, but since I’m still up up to the ‘apprentice automotive electrician’ level yet, some of what I transcribe here might take a little tweaking in the future for better clarity. First of all, I’m not entirely sure whether I was simply misunderstanding other’s descriptions of a shunt or whether it was a general misconception, but if I WAS understand correctly, then we’re going to need to ‘un-learn’ what we thought we knew about the ammeter in Ford pickups.

Connecting Amp Meters to Shunt Bars

Because measuring current in this manner requires the meter be made part of the circuit, it is a more difficult type of measurement to make than either voltage or resistance. Some digital meters, like the unit shown in the illustration, have a separate jack to insert the red test lead plug when measuring current. Other meters, like most inexpensive analog meters, use the same jacks for measuring voltage, resistance, and current.

When an ammeter is placed in series with a circuit, it ideally drops no voltage as current goes through it. In other words, it acts very much like a piece of wire, with very little resistance from one test probe to the other. Consequently, an ammeter will act as a short circuit if placed in parallel across the terminals of a substantial source of voltage.

Dec 13,  · I just got a DC A meter and DC A 75mV shunt. From the wiring diagram I’ve gotten with it, it seems like it’s showing how to wire it up to see how much you are drawing.. I’m trying to hook mine up so I can see how much my panels are making.

Rating Newest Oldest Best Answer: To work properly, an amp-meter must be in series with the entire positive cable feeding the boat’s electrical systems EXCEPT the large cable going directly to the starter. If your battery’s positive terminal has only one large cable hooked to it, you’ll have to trace the cable to the terminal strip or buss panel where you find the large cable that goes directly to the starter motor and the second main positive cable that feeds all the boat’s other electrical systems.

If such doesn’t exist, then you will have to be creative in splitting the boat’s main power line from the starter’s large cable because the amp-meter will be hooked only in series inline with the cable feeding the boat’s main power buss excluding the starter cable. This allows the meter to indicate a discharge when the engine isn’t running, and show the total alternator charge current minus system discharge current to the battery when the engine is running.

Once you’ve got a place to break the main positive cable feeding only the boat’s electrical systems, it’s probably going to be back near the battery and your amp-meter is probably going to be installed up on the boat’s dash or control panel. If you use a standard “inline” or series amp-meter, the cables running to and from the meter back to where you cut the main power cable will be fairly long; so, to prevent loss of voltage voltage drop with higher current demands through a very long battery cable, you should use cable that’s at least the next wire gauge larger than the existing battery cable.

A much easier way of doing this is to shop around for a “remote sensing” amp-meter instead of a conventional “inline” or series meter. The remote-sensing meter has a shunt pickup device that’s quickly connected up between the heavy battery cable ends back at the point where you cut the main cable; then, only two small meter feeding wires are ran forward to the meter itself.
