Any ideas how I can get this thing to work like it's supposed to?
if you didnt let all of its smoke out convert it back to six volts.

Is that extra, smaller spring needed on the bottom of the steering wheel?
if it came with the truck then i would tend to believe so. since i only have had to play with the one on my 40 and its different from what you have.

get a six volt battery and hook it up to that. in the maintenance manual there are instructions on how to play with the horn. maybe it's not fried and only needs an internal cleaning and adjustment.
