They have electronic ones around here. The one where UP crosses IL 176 sounds sick. Somebody needs to put it out of its misery.
C man, I am waiting to take pixs of it for you.
Torby, ever hear a microprocessor (sp) one? Thing is you can not unless your out of the car and standing beside it! /DesktopModules/NTForums/themes/mls/emoticons/laugh.gif Now there sick /DesktopModules/NTForums/themes/mls/emoticons/sick.gif
I have one (somewhere) just like that one. If it does not work according to the schematic, take it to an electrical friend, the circuit is very simple... you either have it wired wrong, or both coils or the contacts are out.
By the way, when the arm comes down to touch the magnets, the long springy thing should break contact. It looks like the arm is down and the contact is still contacting.
I believe Greg is correct. From the pictures it looks like with the armature all the way down against the two solenoids there should approximately 1/16" between the item labeled 3 in the diagram displayed in the seventh picture down (i.e. Greg's springy thing) and the mating contact that moves up and down with the armature. To adjust for that 1/16" gap, first don't have any power applied to the bell, then loosen the screw labeled 5 in the diagram slightly. Then while holding the armature down against the two solenoids, tap the item labeled 2 in the diagram down, which is to the left of the screw (i.e. item 5) you just loosened, until you get the 1/16" gap. Then tighten the screw back down and double check that you still have the 1/16" gap.
Next locate the terminal block that has three posts, it's just to the bottom-left of the solenoids. The post on the far left, which has the one wire and connects to the bottom of the adjustable resistor, located up and slightly to the left. Is where you connect the positive lead of your power supply.
The middle post in the terminal block is where you connect the negative lead of your power supply.
If the speed of the bell ringing is to fast or to slow, I'm fairly sure you use the band on the adjustable resister.
To adjust the resistor, first disconnect the power then loosen the screw that holds the band going around the resistor, then slide the band up or down a little bit and retighten the screw, reattach the power and see what has happened. One way will cause the bell to ring faster, the other way will slow the ring down.
Hope the above works for you, if not then let us know.
Oh man, Steve, you gave me this info at night???? /DesktopModules/NTForums/themes/mls/emoticons/w00t.gif I will not be able to sleep..../DesktopModules/NTForums/themes/mls/emoticons/crazy.gif
This is GREAT!!!! I owe you a ??? and a hand shake!
Now @ 4:30am the bell shall toll /DesktopModules/NTForums/themes/mls/emoticons/whistling.gif, I live in the woods but have nice people around me
Let ya'll know next pm if it works.
Did I remember to say I have a full fuction air raid siren, steam whistle, 2 light target and now this. Yeah, I am a kid!
Want a bell (17", I think) but dang they want way to much /DesktopModules/NTForums/themes/mls/emoticons/blink.gif
Bell rang fine, slow but it was on a slow ring and 12v!
The right stub is POS and far left stub is NEG. I used my truck battery to check and ya'll did not tell me to wear ear plugs /DesktopModules/NTForums/themes/mls/emoticons/crying.gif
