My 11 year old son's Admiral 30A1 restoration project

[Kamakiri]

All righty! Back on this one with my son

Found that this big resistor bought the farm, so it needs replacement. As pictured, the top wire was dismounted for testing.

Now here's the weird thing.....only two wires are hooked up on it which leads me to believe that only one value of the resistor is used. However, the diagram shows all three with the other ends just loose in space??

Question is, do I just order the one section that's used, or for some reason, all three?

I'm 99% sure I know the answer, but it never hurts to double check......
