I test the wire with a meter before attaching by one lead to ground, other to wire. Once attached i put on lead to ground and one to the terminal on choke.
Maybe it is only supposed to draw .5 but seems strange to me.

It's not drawing 0.5V; you're reading a 0.5V differential to ground after connecting the choke coil. If you want to see what current the choke heater draws, you need to connect the ammeter in series with the coil heater.
I think your reading just indicates that the choke heater coil is getting 12V; the 0.5V reading indicates there is more resistance in the coil circuit than there is in your meter.
Sounds right to me, but I'm no electrician.
