In general, an ammeter needs to be installed between the device providing electricity and the device(s) using electricity. This kind of connection, where you break the wire and install the meter across the break, is called a "series" connection. In an automobile, the ammeter should be installed in the smaller of the two positive (usually red) battery cables, the one that runs from the positive battery terminal to the alternator charging terminal (and also to rest of the non-starter electrical loads). Here is a simple drawing: B+ ------(\)---------- A+ ---------- ACC
ST Where: (\) = The Ammeter
B+ = Positive Battery Terminal
A+ = Alternator Charging Terminal
ST = Starter (large cable)
ACC = To vehicle Accessories (small cable) i.e., ignition, lights, etc.
------ = smaller (typically 10 gauge) red wire
= larger battery/starter cable (typically 4 gauge or larger) Notes: * Do not install the ammeter in the large cable that goes to the starter. * The small cable from the Alternator to the battery may be attached to the battery terminal, or it may be attached to the starter terminal. Electrically these are equivalent. * In order for the ammeter to properly show whether the battery is charging or discharging, the ammeter must be installed between (a) the battery and (b) both the alternator and fuse block/ignition switch. * If the accessory cable is also attached to the starter, it will have to be removed and attached to the alternator side of the ammeter or to the alternator as shown in the drawing. * Make sure you disconnect the negative battery terminal before working on the electrical system. ALWAYS wear safety googles whenever working on or near the vehicle battery.

How do you wire in the ammeter on a battery charger?
In series
What are the kinds of ammeter?
The ammeter is a device that measures the electric current. Hot wire, electrostatic, moving iron, moving coil, and induction are the kinds of ammeter.
How do you wire a mooneyes ammeter gauge?
in a series battery, alternator, ignition
Why the windings of an ammeter should be of thick wire?
because lots of current is likely to be flowing through them.however a shunt ammeter is easier to build than the direct ammeter as described above. in a shunt ammeter you use an ordinary meter wound with fine wire and put a small value shunt resistor across it to take almost all the current.
Can ammeter be connected in neutral wire?
No, your live (brown) cable takes the load and pulls the amps from the supply, not the neutral. Your ammeter should be clipped on the live to get a correct reading.
What does a inductive ammeter do?
It measures current by creating a coil around the current carrying wire. Current flowing in the wire induces a current in the amp-meter proportional to the current flowing in the wire.
Why ammeter connects in series and voltmeter in parallel in electric circuit?
Because the ammeter measures the current flowing THROUGH the wire, butthe voltmeter only measures the potential difference between two points.
How do you measure electrical current flow in a copper wire?
Electrical current flow in a copper wire is measured with an ammeter. It is either clamped onto the wire or attached at one end to monitor the amount of current moving through the wire.
How do you calculate the ammeter reading?
The voltage remains the same across the circuit as it is a parallel connection. So, the current across the upper half of the circuit where the ammeter is connected is calculated as I = V/R = 12.04 (total voltage)/12 (Resistance R1) = 1 A. Hence, the ammeter will read 1 A.
What instrument measures both ac and DC?
hot wire ammmeter or a moving iron ammeter will work for ac and dc.
What is current and ammeters?
Current is the amount of electrons flowing. An ammeter reads this value. Typically an ammeter will be placed in series to measure this flow; there are also "clamp on" ammeters that use a small CT. When placed around a wire, the power flowing in the wire will induce a current in the CT, allowing measuremnt without lifting wires.
How would you connect an ammeter if you want to measure the current coming through some device in a circuit?
HOW TO CONNECT AN AMMETER Always connect an ammeter in SERIES in a circuit. Always ensure that the ammeter has a higher reading range than the expected current load, including start-up spikes. An ammeter expected to read a steady current of 13A should have a max range of 20A.
