Purpose of checking ohms of a rebuilt vivi?

[bobothewizard]

So I am in the process of rebuilding Vivi novas and I am not very good with this voltage stuff. What is the purpose of checking the ohms with a multimeter before placing the rebuild nova on to the battery? I was thinking about purchasing one of these Cartomizer and Atomizer Ohm Meter
but even if I did I would have no idea what reading it should be before putting it back on to the battery. I was also going to order some 32 gague wire off the same site since it was fairly cheap for 100 feet.


ALso I have a variable volt battery but how do you know what voltage to run the rebuild heads at, is it a personal preference or is there some science behind it?

You ohm check the coil to make sure there are no shorts that could damage your battery. As for your question about volts, just build the coil to the same ohms that you normaly use with factory coils, and start with your normal voltage, adjust from there if you need to. If you don't remember what ohms you prefer look at one of your vivi heads, it should be stamped on there what the factory wound it to. Common resistances are 1.5, 1.8, 2.0, 2.5, & 3.0.

When you rebuild them do they have to match the ohms printed on the head? Does it matter?

No, they don't.
