I have 2 horns from Pilothouses, one is 1948, the other is 1951. Similar but different. Both are 6Volt. Will they work on 12 volts?? Can I put a resistor inline to drop the voltage?
Also, there are 2 little set screws with locking nuts, can they be used to "tune" the horns??
Thanks
Customers truck is ready to ship. Someone else is doing the body work. I got it running and road worthy. Has a 360 from a 1974 truck w/ grannie gear 4 speed, now.
