Are you sure that you want to delete this answer? Yes Sorry, something has gone wrong. 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.
Digital Volt Amp Panel 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. Only a few mostly high-end coaches utilize the volt from this same service. The amp 3-pole 4-wire service is superior to the amp service because of the total amperage available.

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.
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. Also when tuning an antenna leave all amps out of the circuit. Make sure you have good connectors, coax and antenna setup before you add an amp. Get your antenna setup as best as possible before you do anything. I know I am new here, but I am at least giving you some honest answers. Also read up on bonding of vehicle body parts and such. Helps a bunch if you are serious about getting the best performance out of your entire system.
Watt’s Up DC Amp Meter & Amp Hour Meter Connections
Jun 1, If you want to know how much your meter will draw on the battery when the truck is off, look on the spec sheet that came with your meter for a thing called input impedance. I just looked it up for the voltage ranges of a Fluke multi meter, and it is 10Mohms for that. OK, so it is not infinite, but some meters use an op-amp on the input and do have an “infinite” input impedance. The lower the input impedance, the less accurate your volt meter will be because it loads the circuit with the shunted current path everyone is talking about.
To calculate the parasitic draw, divide the voltage by the input impedance.

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.
It’s much less hassle to install, and there’s no worry about running expensive heavy cable a long distance that could possibly rub and short out at some later time. Unless you’re really concerned about monitoring the amount of discharge or charge in amps , you can do very well with only a voltmeter that’s installed in the control panel and quickly hooked up with small wires between the ground buss and any 12V fuse terminal that’s “hot” all the time.
installing an amp guage
An ammeter must have all the current the vehicle uses except starter running through it to read it properly. If you connect it between the alt and batt it may only read alt output and not show discharge. Also the wire gauges specified are way too low. Fine for an older vehicle putting out 30 amps,but not most newer ones. Hence the reason for shunted type ammeters. They are also alot safer as not all that amperage is running through the vehicle.
Sep 04, · PM – Post# the previous owner of this 63 impala replace the charging, oil pressure and temp lights with aftermarket gauges on the bottom of the dash and the oil and tmp work but there are no wires to the charging/amp meter. i guess he either didn’t know how to wire it because of converting to a 1 wire alternators setup or figured it wasn’t important or something. anyway.
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. If this is done, a surge in current will result, potentially damaging the meter: Ammeters are generally protected from excessive current by means of a small fuse located inside the meter housing.
Be very careful to avoid this scenario! On a meter where the same test lead jacks are used for both resistance and current measurement, simply leave the test lead plugs where they are and touch the two probes together. On a meter where different jacks are used, this is how you insert the test lead plugs to check the fuse:
Hook up sequence?
In the automotive context, a voltmeter gauge displays the number of volts stored by the vehicle’s battery. Many vehicles, particularly older cars, are equipped with only a dashboard light that illuminates when the battery voltage falls below a normal level. Sunpro manufactures volt gauges that instead feature a needle that moves across a numbered dial to indicate exactly how much voltage the battery has.
Although Sunpro produces a number of volt meters that look different, the process of hooking up the gauge is the same regardless of the external appearance.
Feb 24, · Wattmeter/SWR meter should always be between the rig or amp and the tuner, otherwise the readings are irrelevant. If you put the “meter” between the tuner and antenna, it won’t show when the antenna is matched, and will only show the native SWR of the antenna before tuning, which isn’t important information.
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.
When this relay is not energized, the RF goes straight through to the antenna with no amplification and the amp is in standby. Setting the panel switch in standby does the same thing – the relay coil circuit is opened. So, again, when that relay is open, the amp is out of the circuit. On older amps like mine, the relay coil connections are brought out to the hookup point, in this case a terminal strip, and the full relay coil current will be switched by whatever is connected there.
Older rigs have an internal relay that can handle the switching load. Newer rigs have a transistor that can NOT and will get cooked.
