horn resistor etc
i set my ccpu up with 12 volts - ground, i know a sin in some purists eyes. everything is just better on 12v in my personal opinion, as i have converted several bikes and so on to 12 v over the years. i ordered the voltage drop from mikes in ga. the drop looked like some kind of ceramic resistor(didn't appear to be wire wound) with a heat sink. the horn sounded weak but worked, more of an aaaaah......oooooo.......ga. not the crisp sound i wanted. after a dumb mishap i accidently burned the field coils on that horn. i had another horn that blows fine, but wouldn't work at all through the resistor. i wonder if this resistor is passing enough current to blow the horn. i did electrical work all my lifew so i know i've got a circuit all the way to the horn button. if i ground the connection in the switch on the stearing column i get an arc but no noise from the horn.
next question... i'm going to try and rewind the field coils in the first horn. somewhere on this site i saw something about winding twice the turns usinf smaller wire and making the horn 12v. are there any details on this converion? |

24 ga. magnet wire, same direction, twice as many turns. I saw a detailed procedure once somewhere, but I can't find it now. But it ain't rocket science. |

Re: horn resistor etc
Converting the ahooguh to operate from 12-volts is best done by re-wiring the field coils. Dropping resisters on the market do not hold up well with the power requirement.
A friend and I have done several with great success. Attached article may help. A word of caution, when you reassemble the horn make sure you line the center button up correctly with the ratchet wheel. Best to make sure the horn works properly on 6-volts before staring the conversion. Mark how the horn is assembled and reassemble the same way. Tom Endy |

Re: horn resistor etc
thanks guys, you've confirmed my suspicions about the resistor. when i was young in the appliance repair business we would take appliance motors in to be rewound(boy! times have changed) and occasionally watched the guys rewind field coils for those motors. rewinding these coils should be an interesting challenge.
