Post subject:  electric choke power take off

Where is the best place to tap off 12v for a eddy electric choke? right off the ballast resistor??

Also: the eddy instructions say "DO NOT" tap 12v off the coil +.

Why not? what would happen?

Coil + generally is not 12v. It is somewhat less, because of the ballast resistor. Also the additional current drawn by the choke t-stat will cause an additional voltage drop through the ballast resistor, meaning even less voltage available at the coil.

OK. that kind of drop at the coil can cause a misfire, esp. with an elect. ignition. Makes sense.... thanks!

where to take the power then?

Take it from the 12v side(supply) of the ballast resistor, not the side that goes to the coil.
