When the generator is not charging, they just read th battery voltage, which is 12.6V or less depending on the charge in the battery. When the generator is working, it reads 13.7V at around 1000 rpm, or around 14.2V at cruising rpms. It s much easier for me to see the bus voltage than the small ammeter deflection. _____
Connect the red lead to the A port on the ammeter. Note the ports carefully since some devices may have multiple ones. The ampere port, labeled with an A, is the correct one for testing a current''s strength. Ignore the mΩ port if …

4 and 2 amp car battery chargers – 4 and 2 amp battery chargers take a long time to recharge a fully depleted battery and will only work on smaller car batteries. A 4 amp charger takes around 12 hours to charge a 48amp battery; a 2 amp charger could take a full day to charge the same sized battery.
Ammeter Shunt Other Methods to measure Current Magnetic method The magnetic method, we use Hall Effect to measure the current. When a wire is lying with electron flow in it, it has some current flowing inside. But they don''t have electric potential in …
The two solid cables come right off the battery clamp. The multi-wire loom is an inch or two away, at the "back" of the battery clamp. I just thought of something that seems kind of ridiculous but might work. Disconnect the negative clamp from the battery. Connect a jumper cable to the battery and to the clamp.
It is between the alternator and bus, while the ammeter is between battery and bus. Your 172 has an ammeter. If it indicates zero in the runup, and you actuate the flaps, it should stay at zero except for that tiny flicker of the needle. ... If the ammeter is broken, the primary bus is dead. It''s not too hard to figure out that nothing at all ...
