Connect the amp's negative terminal to the car's chassis ground. My guess car companys quit amp meters because other options were cheaper. You need to break the circuit so that all of the current goes to the meter. The balance on your radio may have gotten moved from center to right or left, or your speaker wire may have come disconnected. Set all of the input level gain controls to their lowest setting.
How to Install a Car Volt Amp Gauge
Mopars had direct reading ammeters for a long time, and they are still giving people fits. Similar to whats already posted. Usually, the brown wire is the accessory wire and the green or blue wire will be the main power to the ignition. Step Find the wire that goes to the lighting circuit.
If the radio is good, it could be a bad speaker. Consult the owner's manual or the manufacturer of your amplifier to determine the size fuse you should use. To read the electric meter dial, start with the number digit on the left and read towards the right. Include your email address to get a message when this question is answered.
For me, it's a must have on an ammeter. Would have to pick the right values po protection components to minimize the distortion to the accuracy of the reading, and still provide enough power for the meter. First of all we traced the wires coming from the ammeter back to their source and verified their continuity. The red wire A coming from the discharge side of the ammeter goes through the wiring harness and hooks up to the hot side of the starter solenoid.
Amazing how a few inches of snow can almost shut this city down, its because they don't start plowing til it quits. Near as I can figure the negtative lead goes to the starter motor and the positive lead goes to the generator, plenty of fish but which poll on the gen? It would be nice to get a reading of amps supplied too.
The harness can be seen coming out of the steering column and going into a rectangular connector close to the column. No I am not going to run a volt meter because I cant find one as a replacement for this truck, and I don't want one hanging from the underside of the dash. For me a voltmeter was worthless.

How to Set Up an Ammeter
Wyldman Cool I gotcha now. Each month you read the dial, there are five places to record your readings. Once you've reconnected it, two tops turn the vehicle on and check to see if your amp turned on. An ammeter is a flow meter that show which way the amps are going. Why there had not been a fire is beyond me.
If you look, it is where the meter will also connect. Mentioning it just in case. Turn up the deck's volume until you hear distortion, and set it just below that level.
If someone can confirm this is correct I would be very thankful. An ammeter must have all the current the vehicle uses except starter running through it to read it properly. Step Start your vehicle and verify that the gauge is working. Step Attach an eyelet to the wire running to the grounding point. Electricity is a valubale commodity, especially in modern automobiles.
How do I hook this into a one wire alternator? Maybe I don't need to hook up the ammeter after all. Simplify this for me please.
- If there is no available hole, use a power drill and steel bits to drill one.
- Have you ever wondered how the utility company knows how much power you used each month?
- Generally, the positive wire will be red and the negative will be black.
Hello, thank you for this article. With your diagrams I verified my connection and finally found that load was simply too low. Since it is clear glass, you can see through it. This the device that will measure the power your electrical system uses throughout the month. Step Wrap the wire loom around any exposed wiring.
Release the latch inside the car. Choose something strong and clean sounding. Two yellow wires one of which goes to the ammeter and the other to the voltage regulator and one large black wire with a yellow tracer. The fact that you bought the used ammeter doesn't require you to use it. Step Run a wire from where you are mounting the gauge to the lighting circuit wire.
Wait- you are testing this with cooling fan right? You will rarely have amps going in either direction. Connect the speaker wires from the amplifier to the speakers. Current is measured in amps, and one-thousandth of an amp is called a milliamp.
How to Install a Car Amp (with Pictures) - wikiHow
It simply creates another path for the electricity to travel without exposing the gauge to the high currents of the main circuit. Well almost ready for fire in the hole. Wear hearing protection when adjusting the amp's settings.
Chinese supplier unable to provide any advice or technical data. The other thing we forget in the high tech world is you can still buy fusible links. The utility company brings wires overhead to connect to the meter on the outside, where the hot wires will connect. It is connected to a pipe that connects to your electric meter.
- Wired and testing with load.
- As with the line connection, the load connection has the two hot feeds and the center is the neutral connection.
- Also, there is a lot to read on this link but some good thoughts about Amp meters.
- The process for reading current on a digital multimeter depends on your specific multimeter, but it is similar across most devices.
- Installing a voltage gauge will allow you to see changes in the charging system well before it becomes a serious problem.
- Set equalizers to their center, or neutral, position if you have them.
Paint the hole's edges to protect against rust. This is going through the circuit board. Step Run a wire from the gauge to a grounding point under the dash. Step Install the negative battery cable and tighten until it is snug. You actually can leave black small wire disconnected since they have common ground anyway.
Interesting that the amp guage is actually a shunt, in other words the electrical load is not carried by the gauge. As Jimz said, go with a volt meter. No current is flowing trough there. In other words, it measures the direction of current flow.
If it's a pedal, push it down until you feel the brake engage. If you don't hear distortion even at the loudest setting, the head unit is in good shape. Here is a simple schematic I whipped up showing the factory ammeter wiring. Take that fuse out, wrap the remote wire around it, south and connect it back where it was. Use either butt connectors or the commonly supplied wire taps to connect the voltmeter wires to the wiring harness.
