horns

[Philippe Courant <accf-club@xxxxxxxxxxxxxxxx>]

I've some problem with one of the horn of my '57. It's an Autolite. This 
horn blows one or 2 times then fails. After a while (2 or 3 mn) it blows 
again 2 or 3 (short) times. Etc..
I remove the cover and try to adjust the small screw: blows again then 
fails, i unscrew (or screw) a little the adj. screw and same results... 
I've spent 1 hours w/o good results... It seems that when the resistor 
is too hot then the horn fails. What's the purpose of this resistor (0.5 
ohm) ? Protection ? Seems that with temperature the value of the 
resistor changes so the adjustement goes wrong.
Could i short the resistor (and adjust the sound) w/o burning the coil ?
Note that the 2 other horns work well ..
