To determine what coil you have and if it needs a resistor, disconnect one or both primary coil terminals (the + and - studs on top).
Set the knob on the meter to X10 ohms. You will be reading the top scale. Touching the leads together should swing the needle to the 0 on the right. If not the battery may be low or there may be an adjustment.
Touch the leads to the coil terminals. Wiggle them around to get a good steady reading.
A true 12v coil, one that does not need a resistor, will show about 3 ohms resistance.
A 6v coil OR a 12v that is designed to operate with a resistor will show about 1.5 ohms.
End result, for a 12v system, you want either a 3 ohm coil and no resistor, or a 1.5 ohm coil used with a 1.5 ohm resistor in series ahead of the coil on the incoming voltage from the switch.
Simply testing voltage before and after the coil will not give you an answer.

As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
