3ohms seems kinda high for twisted 32 with a 5/6 wrap. I would expect you to be around the 2ohm mark. I did a 4/5 wrap on mine with 32 and I ended up with a 1.5ohm coil. Are you sure you're coil ends are secured tightly under the screws? You may be picking up extra ohms from a loose connection.
I'll check those connections, 'cause I thought it was high too. When I first put it on the VAMO it was reading 2.3 - 2.4 ohms.
PS, just checked it again and now it's reading 5 ohm!!! Definitely got look see...
