Cvk Choke ac or dc?

[magoconnor]

Hello. 

Does the choke run on ac or dc? 
I have seen diagrams where it gets ac directly from the stator, and others where its supplied from the battery (dc). 
What do you think I should do?

Connect the enricher to the stator.

Runs on AC. Manufacturers don't want the enricher to engage with the key so you don't turn the key, wait a while and now your enricher is already shut off. It gets power from the stator, so as soon as the engine fires up the thermoplastic will start to heat up and slowly shut off the enrichment after almost a minute, at this time your engine should be at a healthy running temperature.

Ok just to make sure.
I should just run it straight of the yellow wire coming from the stator? nothing in between?
