Couple things. A stator puts out an ac voltage. It is essentially a small generator. It's frequency and voltage depends on model, poles, and cranking RPM. I mostly use mine for work on older outboard motors where voltage is <400v. It is a standard tool when working on outboards. The frequency spec you are looking at is the frequency the meter can measure you need to look at the ac voltage at which which frequency range the meter can measure, it's called bandwidth. Without looking up that meter it is probably in the 50-75Hz range, as most basic meters are designed. I think I actually have that meter but in craftsman clothes. That meter will not work by itself. For a few reasons. If you want to discuss it further in depth we can. It will give you a goofy averaged value probably somewhere in the 50-70v range.
You will either need a higher end meter with a larger ac frequency range (labeled bandwidth in meter specs), a DVA peak detector or an oscilloscope. If you are sure the max voltage you are going to get out of your stator is only ~100v that is pretty low and you should be able to find parts pretty easily. The ingnition pulse generator is commonly called the trigger and is what starts the whole process. Do a search for homebuilt DVA, it will probably take you to a boating forum with a simple schematic and instructions.
Do you have the service manual for the quad you are working on?
