Electric choke issue

Ok so I'll try and respond to all, apologies if I miss anyone.

The choke is wired up to a 10 amp keyed circuit that American specifically lists for this purpose. When the key is off, 0 Volts, when key is in run position, 12.25 volts.

I believe the choke cap is fried internally. It only has 5 ohms resistance. From what I've found, it should be between 12 and 20 ohms. If I disconnect the hot lead, I can connect the battery and the engine will crank and all electrical works. If it's not this, then potentially, the America Autowire fuse block could have a problem. But the fact that the choke wire is dead when the key is off tells me that's not the case. It also has no continuity to ground unless it's plugged into the choke.

The alternator is single wire now with no field connection per the AW diagram and the Mancini ignition instructions. Headlights brake lights signals all function as expected, hazard switch functions but not well, not shorting out though as far as I can tell with the meter. Radio isn't in the car but as with all other open connections, they are terminated and insulate (accessory plug, heater, windshield wiper).

I have a other carb with electric choke that I'm going to pull out and test. If I have the same issue then I'll be reaching out to American for help as there are no fuse block diagrams available.

Let me know if I've missed anything, please!

Another question, should the negative post on the could have continuity to the positive post and should it have continuity to ground/negative battery post?

67dart273, you helped me find my first electrical issue with this car 2 years ago. Forever grateful!
