1970 340 Swinger steering column gets hot

Also keep in mind that this could be engine compartment/manifold heat drafting up the shaft, and may not be an electrical issue at all.
Very much could be true...you could test for this. Turn key on, and whatever else..disconnect your ignition from the coil, maybe a battery charger and let the car sit for an hour.....see if the column heats up....good one @TrailBeast !
