"ok so on the coil I see where it connects to the switch then it has a round terminal that has the wire that goes off to the distributors. Are these the primary connectors...sorry my strong point."
The two small screw terminals (may be + and -, may be BAT and DIST) are the Low Voltage primary, one wires to ignition switch, other wires to the small side terminal on distributors.
If its a 12 volt typical stock farm tractor it will be around 2.5 to 4 ohms (many around 3), if its a 6 volt it will be more like 1.25 to 2 ohms range (many around 1.5)
The big center HV Tower is the High Voltage Secondary output which uses a coil wire to feed the center of the distributor cap (its HV input). It will read several thousand ohms.
"I have a fluke volt meter think that will be good enough"
Probably assuming it has a low ohms scale.
NOTE the low voltage low energy ohm meter test will ONLY show if a coil is definitely bad such as an open Primary or Secondary. It can pass both continuity and ohms tests and still be bad as many failures happen under HV breakdown and/or after warmed up.
