Stewart Warner Horn Wiring
I just acquired an SW horn that works, but I’m fairly sure the coils have been re-wound for 12 volts. It works quite well on 12 volts, but not nearly so well on 6 volts.
I recall reading an article about rewinding horn coils and seem to remember that 6 volt horn coils have about 50 turns of wire and 12 volt coils have twice that. 2 questions - 1. Do the coils appear to be wound for 12 volts ? 2. Can I just unwind half the turns to convert it back to 6 volts ? Many thanks - Jim |

Rewiring the ahooguh is not a difficult task. See attached article.

Be aware that in the Stewart Warner horn the screw on the end of the armature holding the ratchet wheel on is LEFT HAND THREADS!
