An ammeter has very low resistance. When you put it in series, you put its (low) resistance in series with the rest of the circuitry. The current that flows will be determined by the total resistance, i.e. the sum of the ammeter and the rest of the circuit. As the ammeter''s resistance is very low, the total current will be very similar to the current that would flow …
I had the concept that in order to check the maximum current a battery can supply, it is fine to connect an ammeter in series with battery because ammeter has low resistance in series and this will yield the maximum current a battery can supply. Many people have said it is wrong, but I can''t understand why.

When it gets the signal, it takes the power from the car battery and closes a switch so that this power can be used to turn the starter motor and the engine. There are many reasons why a starter solenoid can fail to work properly. Sometimes the solenoid can be fine and the problem can be with the battery or the starter motor.

The battery going bad could also provide those symptoms, but don''t be surprised if you need a new PTO clutch ($300 for an off brand one). That your battery was dead when you started suggest you might be lucky and it isn''t the clutch, but I''d put a battery maintainer (battery tender brand or similar) on that battery for a day before using it again.

All wires are considered ideal; that is, they have zero resistance. We will assume for now that all other elements of the circuit are ideal, too: The value of resistance Ris a constant, the internal resistances of the battery (Tint) and the ammeter (TA) are zero, and the internal resistance of the voltmeter (rv) is infinitely large. (Figure 1)
So why not just have the surplus of electrons on one end go to ground to equalize (e.g. 5 volts to 0 volts should produce current)? Why does it have to be the other end of the battery? I''m sure there''s atoms/molecules in the ground that could accept the extra electrons (receivers atoms/molecules for the donors in the battery).
