Ammeter
If you have continuity on both wires between where the ammeter is getting power from and the terminal end on the gauge (with the gauge NOT wired) and then when the battery is hooked up you show power on both wires at the gauge (and you need to have the gauge still disconnected) then if the gauge is then hooked up and the headlights turned on ...
Battery takes charge with charger but Ammeter in negative when running
The battery has not been removed and has been in the mower for better than 5 years. This started when I turned the mower off for a bathroom break and when I came back the mower would not start so I jumped it with a battery charger with a quick start mode. While finishing mowing I noticed the Ammeter was reading -8 (Negative).
BYPASS the AMMETER? (1969 A12)
When I turned the key to start it, it immediately fried the fusible link at the bulk head. Thank God it was there. I then realized that there was another insulator inside the gauge. That was enough for me. I pulled both wires off of the ammeter and used a screw and nut to secure the two wires together and then insulated it with electrical tape.

What is my Ammeter telling me
During cranking all the power goes from the battery right to the starter. So the ammeter is essentially not part of the circuit. For the most part your description is normal. The 2 wire field with a solid state regulator do …
Ammeter not indicating
Pull the ammeter and connect one terminal to the positive terminal on a battery. Connect the other ammeter terminal to one side of a minimum 12 volt landing light bulb. Connect the other side of the 12v light to the negative terminal on the same battery. If the ammeter needle does not move then its toast.

Can a bad Ampmeter cause no charge?
My ampmeter does not seem to work, and no charge to the battery. I had replaced the harness, and cleaned the termainals well. I also sparked the voltage regulator to polarize the generator. Looks like the ampmeter is dead, it does not register anything. How to check it? Can it inhibit …
School me on how an ammeter works
A nominal reading of about 14 volts is indication generator/alternator is suppling enough voltage/amperage for systems electrical demand (same as charge on ammeter) and if voltage of system is dropping and going down to lower voltage (12.8 or 13 volt or lower) if shows alternator/generator is not functioning properly and can not sustain system ...
How to Use an Ammeter: 10 Steps (with Pictures)
Most ammeter fuses can be easily replaced or reset, though this process will vary according to your brand and model. Consult your ammeter''s manual to learn how to fix blown fuses. If you adjusted the power range lower to check the fuse, reset the range to its maximum to prevent the fuse from blowing when taking the actual amperage.

20.4: Voltmeters and Ammeters
This is necessary because objects in series experience the same current. They must not be connected to a voltage source — ammeters are designed to work under a minimal burden, (which refers to the voltage drop across the ammeter, typically a small fraction of a volt). Ammeter in Series: An ammeter (A) is placed in series to measure current ...

Probably the largest drop would be when you first turn on the bright headlights. ... It''s not a ammeter in the pure sense given that it is not in series with the load as it would have to be to measure current. ... It lets you know roughly in which direction current is flowing, towards the battery (charging) or away from the battery (discharging ...
How to Use an Ammeter: 10 Steps (with Pictures)

How to Find a Parasitic Battery Drain: 11 Steps (with Pictures)
The ammeter can be connected to either terminal with identical results with one exception: if you get against a metal object while using a positive terminal, there is potential for a short circuit with a shower of sparks. ... If you need to find a parasitic battery drain, turn off all of the vehicle''s electrical components, engage the emergency ...
How to Know When Your Alternator, Starter, or Battery is Going Bad
A jump-start will not start the car; If the battery is fully charged and can hold a charge of 12.6 volts when the car is off, then the battery is probably okay. When you turn the key, if the starter does not engage immediately, or if you only hear a click or clicking, then either a connection is loose, or the starter is bad.

Ammeter Battery Gauge repair advice
To elaborate, an ammeter tell you how much current (amps) is flowing through the wiring in your car. This can indicate the condition of the charging system [positive amp flow after starting or high current drain, then falling back to low current draw after battery is charged up] or the condition of the battery [showing constant drain because battery cannot charge].
