An amp meter will tell if you are charging or discharging. A volt meter will tell you the level of voltage or general level of battery. If system is good it should be something over 12 volts, like 13 or maybe 14 if charging and all is well. If less than 12 volts likely something is wrong, battery not good or not charging. Others with more electrical knowledge may improve on this but basically voltage level is condition of system, amp meter tells you charging or not. If battery is good and you you are charged up amp meter will not read much charge. If you just cranked a while to start it should show a good level of charge for a while to put battery back to full charge, then show much less but still not discharge while running. Turning on lights or ignition with engine not running will show some discharge, more for a bunch of lights than ignition.

The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule.
